 1. 测试环境部署     

# 一、前置准备

 

## 1、检查yum源

[root@host-92 secure]# yum info yum
Loaded plugins: fastestmirror, langpacks
Determining fastest mirrors
Installed Packages
Name        : yum
Arch        : noarch
Version     : 3.4.3
Release     : 161.el7.centos
Size        : 5.6 M
Repo        : installed
.......

# 二、安装主节点MySQL

 

 1、安装MariaDB

yum -y install mariadb mariadb-server

2. 修改MySQL挂载的数据盘等位置,单独格式化文件系统和挂载到相应的目录下面

## 2.1、检查挂载目标盘vdb
[root@huangtj-mysql-01 ~]# ps -ef|grep mysql
mysql    103619      1  0 15:46 ?        00:00:00 /bin/sh /usr/bin/mysqld_safe --basedir=/usr
mysql    103816 103619  0 15:46 ?        00:00:00 /usr/libexec/mysqld --basedir=/usr --datadir=/var/lib/mysql --plugin-dir=/usr/lib64/mysql/plugin --log-error=/var/log/mariadb/mariadb.log --pid-file=/var/run/mariadb/mariadb.pid --socket=/var/lib/mysql/mysql.sock root     107843 102003  0 16:09 pts/1    00:00:00 grep --color=auto mysql

检查根目录的挂载盘
[root@huangtj-mysql-01 ~]# df /
Filesystem     1K-blocks    Used Available Use% Mounted on
/dev/vda4       52927232 1924320  51002912   4% /

检查空闲的目标盘vdb
[root@huangtj-mysql-01 ~]# lsblk -f
NAME   FSTYPE LABEL UUID                                 MOUNTPOINT

检查磁盘写入性能,检查磁盘不能限制数据库的写入能力
[root@host-92 secure]# dd if=/dev/zero of=/data/tmp/tmp.file bs=4k count=1000000
1000000+0 records in
1000000+0 records out
4096000000 bytes (4.1 GB) copied, 1.89153 s, 2.2 GB/s

 

## 2.2、修改数据盘并挂载
#格式化文件系统并挂载分区
mkfs.xfs /dev/vdb
mkdir -p /data/mysql
mount /dev/vdb /data/mysql

#修改/etc/fstab文件
[root@gaoji-zyk-10-8-93-105 mysql]# blkid /dev/vdb
/dev/vdb: UUID="36b8d09c-ae21-46ee-9c2c-3e12773cd696" BLOCK_SIZE="512" TYPE="xfs"
[root@gaoji-zyk-10-8-93-105 mysql]# cat /etc/fstab
UUID=D91D-49A3 /boot/efi vfat defaults 0 0
UUID=61596cb9-d7c9-40ae-9a03-a71f80462a25 /boot ext2 defaults 0 0
UUID=f38b9af0-5dfb-4261-94b7-f0cc0a7ba63f / xfs defaults 0 1
UUID=36b8d09c-ae21-46ee-9c2c-3e12773cd696 /data/mysql xfs rw,suid,dev,exec,auto,nouser,sync,relatime 0 1

#先停止mysql
systemctl stop mariadb
#移动数据:
mv /var/lib/mysql/* /data/mysql/
#创建软连接
ln -s /data/mysql/ /var/lib/mysql/

#修改my.conf
Under [mysqld]:
datadir=/data/mysql
socket=/data/mysql/mysql.sock

Under [client]:
port=3306
socket=/data/mysql/mysql.sock
#启动mysql,保证MySQL文件夹的权限足够 chown -R mysql:mysql /data/mysql/

### 常见问题处理:

- **保证MySQL文件夹的权限足够 chown -R mysql:mysql /data/mysql/**

 

3、启动

启动数据库
systemctl start mariadb
确保重启reboot后数据库能启动
systemctl enable mariadb

4、查看状态 ,需要是activing状态

 

service mariadb status

 

预期结果: Active: active (running)

 

[root@host-92 secure]# service mariadb status
Redirecting to /bin/systemctl status mariadb.service
● mariadb.service - MariaDB database server
   Loaded: loaded (/usr/lib/systemd/system/mariadb.service; enabled; vendor preset: disabled)

5、开启MySQL二进制日志记录

 

执行vim /etc/my.cnf,向文件中写入下面的记录,要求主节点和从节点server-id不冲突且唯一

 

[mysqld]
log-bin=mysql-bin
server-id=24

6、重启mysql服务

systemctl restart mariadb

7、初始化数据库账户密码

1.进入mysql命令行
mysql -uroot
直接回车即可
2.执行
use mysql;
update user set Password=password('xxxxxxx') where User='root';
3.提交修改并检查
flush privileges;
select Host,User,password from user where user='root';
4.退出
quit;
5.重新登录数据库,此时需要密码
mysql -u root -p

8、检查日志记录

 

日志检查查看二进制日志是否开启 :
show global variables like '%log_bin%';
查看主节点二进制列表
SHOW MASTER LOGS;
查看主节点server id
SHOW GLOBAL VARIABLES LIKE '%server%';

MariaDB [(none)]> show global variables like '%log_bin%';
+---------------------------------+-------+
| Variable_name                   | Value |
+---------------------------------+-------+
| log_bin                         | ON    |
| log_bin_trust_function_creators | OFF   |
| sql_log_bin                     | ON    |
+---------------------------------+-------+
3 rows in set (0.00 sec)

MariaDB [(none)]> SHOW MASTER LOGS;
+------------------+------------+
| Log_name         | File_size  |
+------------------+------------+
| mysql-bin.000001 |        351 |
| mysql-bin.000002 | 1073904425 |
| mysql-bin.000003 | 1074371223 |
| mysql-bin.000004 | 1074895548 |
.......

MariaDB [(none)]> SHOW GLOBAL VARIABLES LIKE '%server%';
+----------------------+-------------------+
| Variable_name        | Value             |
+----------------------+-------------------+
| character_set_server | latin1            |
| collation_server     | latin1_swedish_ci |
| server_id            | 24                |
+----------------------+-------------------+

 

9、在主节点上创建有复制权限的用户

GRANT REPLICATION SLAVE ON *.* TO 'repl_master'@'xxxxx' IDENTIFIED BY 'xxxxxx';
update user set Password=password('xxxxxxx') where User='repl_master';
flush privileges;

select * from mysql.user;, 预期结果如下
*************************** 7. row ***************************
                  Host: xx.xx.xx.xx
                  User: repl_master
              Password: ***********************
           Select_priv: Y
           Insert_priv: Y
           Update_priv: Y
           Delete_priv: Y
           Create_priv: Y
             Drop_priv: Y
           Reload_priv: Y
         Shutdown_priv: Y
          Process_priv: Y
             File_priv: Y
            Grant_priv: N
       References_priv: Y
            Index_priv: Y
            Alter_priv: Y
          Show_db_priv: Y
            Super_priv: Y
 Create_tmp_table_priv: Y
      Lock_tables_priv: Y
          Execute_priv: Y
       Repl_slave_priv: Y
      Repl_client_priv: Y
      Create_view_priv: Y
        Show_view_priv: Y
   Create_routine_priv: Y
    Alter_routine_priv: Y
      Create_user_priv: Y
            Event_priv: Y
          Trigger_priv: Y
Create_tablespace_priv: Y
              ssl_type:
            ssl_cipher:
           x509_issuer:
          x509_subject:
         max_questions: 0
           max_updates: 0
       max_connections: 0
  max_user_connections: 0
                plugin:
 authentication_string:

 

备注:repl_master, xx.xx.xx.xx, 是要给从节点使用并执行复制权限,分别表示从节点使用的账户、从节点IP、账户密码;当前用例的数据是mock的,不代表真实的IP、账号和密码

 9、锁表

在从节点开始同步之前,对主节点数据库进行锁表操作,最好不要在源库持续大量写入数据的场景下建立主从连接!

此时,如果条件允许 为了同步前数据一致,建议锁定一下表 :
flush tables with read lock;
查看【Master(主库)】状态:
SHOW MASTER STATUS;
记录二进制文件名 (masterl-bin.00000*) 和位置 (Position) (如果有多个二进制文件名,取最后一个的名称和位置!!),确保同步点正常!

MariaDB [(none)]> SHOW MASTER STATUS;
+------------------+-----------+--------------+------------------+
| File             | Position  | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+-----------+--------------+------------------+
| mysql-bin.000001 |      832  |              |                  |
+------------------+-----------+--------------+------------------+
1 row in set (0.00 sec)

# 三、安装从节点

 

## 1-3、从节点安装数据库

 

先执行步骤二里面主节点安装顺序里的【1、2、3】,然后按照下面的顺序执行!

 

## 4、开启relay log

[mysqld]
server-id=23
relay-log=slave-relay-log
relay-log-index=slave-relay-log.index

## 5、同步binlog

**需要主服务器主机名,登陆凭据**,**二进制文件(最后一个)的名称和位置**

mysql -urepl_master -p -h10.0.1.3

停止从节点同步
stop slave;
reset slave;
关联主节点账户和binlog信息
CHANGE MASTER TO MASTER_HOST='xx.xx.xx.xx', MASTER_USER='repl_master', MASTER_PASSWORD='xxxxxxx', MASTER_LOG_FILE='mysql-bin.000001', MASTER_LOG_POS=832;
开启主从同步
start slave;
show slave status;

## 6、检查主从同步状态

show slave status;
输出:
Slave_IO_Running: Yes
Slave_SQL_Running: Yes

MariaDB [(none)]> show slave status\G;
*************************** 1. row ***************************
               Slave_IO_State: Waiting for master to send event
                  Master_Host: ***********
                  Master_User: repl_master
                  Master_Port: 3306
                Connect_Retry: 60
              Master_Log_File: mysql-bin.000416
          Read_Master_Log_Pos: 100147369
               Relay_Log_File: slave-relay-log.000025
                Relay_Log_Pos: 100147653
        Relay_Master_Log_File: mysql-bin.000416
             Slave_IO_Running: Yes
            Slave_SQL_Running: Yes
              Replicate_Do_DB:
          Replicate_Ignore_DB:
           Replicate_Do_Table:
       Replicate_Ignore_Table:
      Replicate_Wild_Do_Table:
  Replicate_Wild_Ignore_Table:
                   Last_Errno: 0
                   Last_Error:
                 Skip_Counter: 0
          Exec_Master_Log_Pos: 100147369
              Relay_Log_Space: 100147990
              Until_Condition: None
               Until_Log_File:
                Until_Log_Pos: 0
           Master_SSL_Allowed: No
           Master_SSL_CA_File:
           Master_SSL_CA_Path:
              Master_SSL_Cert:
            Master_SSL_Cipher:
               Master_SSL_Key:
        Seconds_Behind_Master: 0
Master_SSL_Verify_Server_Cert: No
                Last_IO_Errno: 0

               Last_SQL_Errno: 0
               Last_SQL_Error:
  Replicate_Ignore_Server_Ids:
             Master_Server_Id: 24
1 row in set (0.00 sec)

## 7、解锁主库表

 

unlock tables;

 

# 四、Sysbench部署

## 1、安装压测工具

下载sysbench安装包

 yum -y install make automake libtool pkgconfig libaio-devel
 yum -y install mariadb-devel openssl-devel
 yum -y install postgresql-devel
./autogen.sh
##运行autogen.sh
./configure --prefix=/usr --mandir=/usr/share/man
make
##编译
make install

## 2、安装完成后会有一些 lua 脚本

[root@mgr1 src]# ll /usr/share/sysbench/
total 132
-rwxr-xr-x. 1 root root 1452 May 8 2020 bulk_insert.lua
-rw-r--r--. 1 root root 14369 May 8 2020 oltp_common.lua
-rwxr-xr-x. 1 root root 1290 May 8 2020 oltp_delete.lua
-rwxr-xr-x. 1 root root 2415 May 8 2020 oltp_insert.lua

## 3、部分lua脚本说明

insert.lua 单值插入数据
bulk_inert.lua 批量插入数据
delete.lua 删除数据
select.lua 简单主键查询
oltp.lua 混合读写测试

## 4、sysbench参数

MySQL连接信息参数
--mysql-host:MySQL服务器主机名,默认localhost;如果在本机上使用localhost报错,提示无法连接MySQL服务器,改成本机的IP地址应该就可以了。
--mysql-port:MySQL服务器端口,默认3306
--mysql-user:用户名
--mysql-password:密码

MySQL执行参数
--oltp-test-mode:执行模式,包括simple、nontrx和complex,默认是complex。simple模式下只测试简单的查询;nontrx不仅测试查询,还测试插入更新等,但是不使用事务;complex模式下测试最全面,会测试增删改查,而且会使用事务。可以根据自己的需要选择测试模式。
--oltp-tables-count:测试的表数量,根据实际情况选择
--oltp-table-size:测试的表的大小,根据实际情况选择
--threads:客户端的并发连接数
--time:测试执行的时间,单位是秒,该值不要太短,可以选择120
--report-interval:生成报告的时间间隔,单位是秒,如10

测试前准备:

主库上创建database:create  database sbtest; 

在sysbench机器上跑下面测试:

准备数据:

sysbench ./tests/include/oltp_legacy/oltp.lua --mysql-host=xx.xx.xx.xx --mysql-port=3306 --mysql-user=root --mysql-password='xxxxxxx' --oltp-test-mode=complex --oltp-tables-count=50 --oltp-table-size=100000 --threads=512 --time=300 --report-interval=1 prepare

跑测试:

sysbench ./tests/include/oltp_legacy/oltp.lua --mysql-host=xx.xx.xx.xx --mysql-port=3306 --mysql-user=root --mysql-password='xxxxxxx' --oltp-test-mode=complex --oltp-tables-count=50 --oltp-table-size=100000 --threads=512 --time=36000 --report-interval=1 run

清理数据:

sysbench ./tests/include/oltp_legacy/oltp.lua --mysql-host=xx.xx.xx.xx --mysql-port=3306 --mysql-user=root --mysql-password='xxxxxxx' --oltp-test-mode=complex --oltp-tables-count=50 --oltp-table-size=100000 --threads=512 --time=300 --report-interval=1 cleanup

#先停止mysql
systemctl stop mariadb
#移动数据:
mv /var/lib/mysql/* /data/mysql/
#创建软连接
ln -s /data/mysql/ /var/lib/mysql/

#修改my.conf
Under [mysqld]:
datadir=/data/mysql
socket=/data/mysql/mysql.sock

Under [client]:
port=3306
socket=/data/mysql/mysql.sock
#启动mysql,保证MySQL文件夹的权限足够 chown -R mysql:mysql /data/mysql/

### 常见问题处理:

- **保证MySQL文件夹的权限足够 chown -R mysql:mysql /data/mysql/**

 

3、启动

启动数据库
systemctl start mariadb
确保重启reboot后数据库能启动
systemctl enable mariadb

4、查看状态 ,需要是activing状态

 

service mariadb status

 

预期结果: Active: active (running)

 

[root@host-92 secure]# service mariadb status
Redirecting to /bin/systemctl status mariadb.service

5、开启MySQL二进制日志记录

 

执行vim /etc/my.cnf,向文件中写入下面的记录,要求主节点和从节点server-id不冲突且唯一

 

[mysqld]
log-bin=mysql-bin
server-id=24

6、重启mysql服务

systemctl restart mariadb

7、初始化数据库账户密码

1.进入mysql命令行
mysql -uroot
直接回车即可
2.执行
use mysql;
update user set Password=password('xxxxxxx') where User='root';
3.提交修改并检查
flush privileges;
select Host,User,password from user where user='root';
4.退出
quit;
5.重新登录数据库,此时需要密码
mysql -u root -p

8、检查日志记录

 

日志检查查看二进制日志是否开启 :
show global variables like '%log_bin%';
查看主节点二进制列表
SHOW MASTER LOGS;
查看主节点server id
SHOW GLOBAL VARIABLES LIKE '%server%';

MariaDB [(none)]> show global variables like '%log_bin%';
+---------------------------------+-------+
| Variable_name                   | Value |
+---------------------------------+-------+
| log_bin                         | ON    |
| log_bin_trust_function_creators | OFF   |
| sql_log_bin                     | ON    |
+---------------------------------+-------+
3 rows in set (0.00 sec)

MariaDB [(none)]> SHOW MASTER LOGS;
+------------------+------------+
| Log_name         | File_size  |
+------------------+------------+
| mysql-bin.000001 |        351 |
| mysql-bin.000002 | 1073904425 |
| mysql-bin.000003 | 1074371223 |
| mysql-bin.000004 | 1074895548 |
.......

MariaDB [(none)]> SHOW GLOBAL VARIABLES LIKE '%server%';
+----------------------+-------------------+
| Variable_name        | Value             |
+----------------------+-------------------+
| character_set_server | latin1            |
| collation_server     | latin1_swedish_ci |
| server_id            | 24                |
+----------------------+-------------------+

 

9、在主节点上创建有复制权限的用户

GRANT REPLICATION SLAVE ON *.* TO 'repl_master'@'xxxxx' IDENTIFIED BY 'xxxxxx';
update user set Password=password('xxxxxxx') where User='repl_master';
flush privileges;

select * from mysql.user;, 预期结果如下
*************************** 7. row ***************************
                  Host: xx.xx.xx.xx
                  User: repl_master
              Password: ***********************
           Select_priv: Y
           Insert_priv: Y
           Update_priv: Y
           Delete_priv: Y
           Create_priv: Y
             Drop_priv: Y
           Reload_priv: Y
         Shutdown_priv: Y
          Process_priv: Y
             File_priv: Y
            Grant_priv: N
       References_priv: Y
            Index_priv: Y
            Alter_priv: Y
          Show_db_priv: Y
            Super_priv: Y
 Create_tmp_table_priv: Y
      Lock_tables_priv: Y
          Execute_priv: Y
       Repl_slave_priv: Y
      Repl_client_priv: Y
      Create_view_priv: Y
        Show_view_priv: Y

    Alter_routine_priv: Y
      Create_user_priv: Y
            Event_priv: Y
          Trigger_priv: Y
Create_tablespace_priv: Y
              ssl_type:
            ssl_cipher:
           x509_issuer:
          x509_subject:
         max_questions: 0
           max_updates: 0
       max_connections: 0
  max_user_connections: 0
                plugin:
 authentication_string:

 

备注:repl_master, xx.xx.xx.xx, 是要给从节点使用并执行复制权限,分别表示从节点使用的账户、从节点IP、账户密码;当前用例的数据是mock的,不代表真实的IP、账号和密码

 9、锁表

在从节点开始同步之前,对主节点数据库进行锁表操作,最好不要在源库持续大量写入数据的场景下建立主从连接!

此时,如果条件允许 为了同步前数据一致,建议锁定一下表 :
flush tables with read lock;
查看【Master(主库)】状态:
SHOW MASTER STATUS;
记录二进制文件名 (masterl-bin.00000*) 和位置 (Position) (如果有多个二进制文件名,取最后一个的名称和位置!!),确保同步点正常!

MariaDB [(none)]> SHOW MASTER STATUS;
+------------------+-----------+--------------+------------------+
| File             | Position  | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+-----------+--------------+------------------+
| mysql-bin.000001 |      832  |              |                  |
+------------------+-----------+--------------+------------------+
1 row in set (0.00 sec)

# 三、安装从节点

 

## 1-3、从节点安装数据库

 

先执行步骤二里面主节点安装顺序里的【1、2、3】,然后按照下面的顺序执行!

 

## 4、开启relay log

[mysqld]
server-id=23
relay-log=slave-relay-log
relay-log-index=slave-relay-log.index

## 5、同步binlog

**需要主服务器主机名,登陆凭据**,**二进制文件(最后一个)的名称和位置**

mysql -urepl_master -p -h10.0.1.3

停止从节点同步
stop slave;
reset slave;
关联主节点账户和binlog信息
CHANGE MASTER TO MASTER_HOST='xx.xx.xx.xx', MASTER_USER='repl_master', MASTER_PASSWORD='xxxxxxx', MASTER_LOG_FILE='mysql-bin.000001', MASTER_LOG_POS=832;
开启主从同步
start slave;
show slave status;

## 6、检查主从同步状态

show slave status;
输出:
Slave_IO_Running: Yes
Slave_SQL_Running: Yes

MariaDB [(none)]> show slave status\G;
*************************** 1. row ***************************
               Slave_IO_State: Waiting for master to send event
                  Master_Host: ***********
                  Master_User: repl_master
                  Master_Port: 3306
                Connect_Retry: 60
              Master_Log_File: mysql-bin.000416
          Read_Master_Log_Pos: 100147369
               Relay_Log_File: slave-relay-log.000025
                Relay_Log_Pos: 100147653
        Relay_Master_Log_File: mysql-bin.000416

  Replicate_Ignore_Server_Ids:
             Master_Server_Id: 24
1 row in set (0.00 sec)

## 7、解锁主库表

 

unlock tables;

 

# 四、Sysbench部署

## 1、安装压测工具

下载sysbench安装包

 yum -y install make automake libtool pkgconfig libaio-devel
 yum -y install mariadb-devel openssl-devel
 yum -y install postgresql-devel
./autogen.sh
##运行autogen.sh
./configure --prefix=/usr --mandir=/usr/share/man
make
##编译
make install

## 2、安装完成后会有一些 lua 脚本

[root@mgr1 src]# ll /usr/share/sysbench/
total 132
-rwxr-xr-x. 1 root root 1452 May 8 2020 bulk_insert.lua
-rw-r--r--. 1 root root 14369 May 8 2020 oltp_common.lua
-rwxr-xr-x. 1 root root 1290 May 8 2020 oltp_delete.lua
-rwxr-xr-x. 1 root root 2415 May 8 2020 oltp_insert.lua

## 3、部分lua脚本说明

insert.lua 单值插入数据
bulk_inert.lua 批量插入数据
delete.lua 删除数据
select.lua 简单主键查询
oltp.lua 混合读写测试

## 4、sysbench参数

MySQL连接信息参数
--mysql-host:MySQL服务器主机名,默认localhost;如果在本机上使用localhost报错,提示无法连接MySQL服务器,改成本机的IP地址应该就可以了。
--mysql-port:MySQL服务器端口,默认3306
--mysql-user:用户名
--mysql-password:密码

MySQL执行参数
--oltp-test-mode:执行模式,包括simple、nontrx和complex,默认是complex。simple模式下只测试简单的查询;nontrx不仅测试查询,还测试插入更新等,但是不使用事务;complex模式下测试最全面,会测试增删改查,而且会使用事务。可以根据自己的需要选择测试模式。
--oltp-tables-count:测试的表数量,根据实际情况选择
--oltp-table-size:测试的表的大小,根据实际情况选择
--threads:客户端的并发连接数
--time:测试执行的时间,单位是秒,该值不要太短,可以选择120
--report-interval:生成报告的时间间隔,单位是秒,如10

测试前准备:

主库上创建database:create  database sbtest; 

在sysbench机器上跑下面测试:

准备数据:

sysbench ./tests/include/oltp_legacy/oltp.lua --mysql-host=xx.xx.xx.xx --mysql-port=3306 --mysql-user=root --mysql-password='xxxxxxx' --oltp-test-mode=complex --oltp-tables-count=50 --oltp-table-size=100000 --threads=512 --time=300 --report-interval=1 prepare

跑测试:

sysbench ./tests/include/oltp_legacy/oltp.lua --mysql-host=xx.xx.xx.xx --mysql-port=3306 --mysql-user=root --mysql-password='xxxxxxx' --oltp-test-mode=complex --oltp-tables-count=50 --oltp-table-size=100000 --threads=512 --time=36000 --report-interval=1 run

清理数据:

sysbench ./tests/include/oltp_legacy/oltp.lua --mysql-host=xx.xx.xx.xx --mysql-port=3306 --mysql-user=root --mysql-password='xxxxxxx' --oltp-test-mode=complex --oltp-tables-count=50 --oltp-table-size=100000 --threads=512 --time=300 --report-interval=1 cleanup

测试结果:
