一、zabbix 安装
1. zabbix下载地址
http://repo.zabbix.com/zabbix
2. 安装zabbix server
rpm -Uvh https://repo.zabbix.com/zabbix/4.4/rhel/7/x86_64/zabbix-release-4.4-1.e7.noarch.rpm
yum clean all
yum install zabbix-server-mysql zabbix-web-mysql zabbix-agent zabbix-get zabbix-sender -y
3. 安装zabbix agent
zabbix server端必须要安装一个zabbix agent。
[root]# yum install zabbix-agent -y
[root]# vi /etc/zabbix/zabbix_agentd.con f
PidFile=/run/zabbix/zabbix_server.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=0
Server=x.x.x.x
ServerActive=x.x.x.x:10051
Hostname=zabbix-server
Include=/etc/zabbix/zabbix_agentd.d/*.conf
BufferSize=200
Timeout=30
二、MySQL安装
1.创建mysql文件夹
cd /usr/local
mkdir mysql
2.下载资源完整包，并上传到/usr/local/mysql
3.解压mysql下载包
tar -xvf mysql-8.0.26-1.el7.x86_64.rpm-bundle.tar
4.查询本地有没有已存在安装包和卸载
查询：rpm -qa | grep mariadb
卸载：rpm -e mariadb-libs-5.5.60-1.el7_5.x86_64 --nodeps
5. 安装顺序
rpm -ivh mysql-community-common-8.0.26-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-plugins-8.0.26-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-8.0.26-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-8.0.26-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-8.0.26-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-compat-8.0.26-1.el7.x86_64.rpm
6.开启mysql
systemctl start mysqld
7.查看数据库的初始密码，命令如下：
cat /var/log/mysqld.log | grep password（记录一下密码，修改要用）
8.修改密码
登录：mysql -u root -p
修改：ALTER USER "USER"@"localhost" IDENTIFIED BY "PASSWORD";
三、配置zabbix server
1.导入表，创建zabbix库、zabbix用户、导入zabbix数据
SQL> create database zabbix character set utf8 collate utf8_bin;
SQL> create user 'USER'@'%' identified by 'PASSWORD';
SQL> grant all privileges on zabbix.* to 'USER'@'%';
[root]# zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix
2.配置zabbix-server连接mysql
[root]# vi /etc/zabbix/zabbix_server.conf
LogFile=/var/log/zabbix/zabbix_server.log
LogFileSize=0
PidFile=/run/zabbix/zabbix_server.pid （要和service里的路径一样）
SocketDir=/var/run/zabbix
DBHost=localhost （这里，localhost还是127.0.0.1视情况而定）
DBName=zabbix
DBUser=zabbix
DBPassword=PASSWORD
SNMPTrapperFile=/var/log/snmptrap/snmptrap.log
Timeout=4
AlertScriptsPath=/usr/lib/zabbix/alertscripts
ExternalScripts=/usr/lib/zabbix/externalscripts
LogSlowQueries=3000
3.启动zabbix server
[root]# systemctl start zabbix-server
[root]# systemctl enable zabbix-server
4.修改zabbix前端PHP配置
修改时区
[root]# vi /etc/httpd/conf.d/zabbix.conf
php_value date.timezone Asia/Shanghai
5.关闭firewall、selinux
systemctl stop firewalld.service
systemctl disable firewalld.service
vi /etc/selinux/config
将SELINUX改成disable（重启后生效）
6.启动httpd服务
[root]# vi /etc/httpd/conf
修改ServerName x.x.x.x:80 (同zabbix_agentd.conf中的server地址)
[root]# systemctl start httpd
[root]# systemctl enable httpd
7.登录zabbix web
http://x.x.x.x/zabbix
初始：Admin/zabbix
界面右上角 用户-修改密码为PASSWORD 语言改为中文。
四、web端配置
1.创建主机
配置--主机--创建主机
2.配置加密
配置--主机--选择一台主机--加密
共享密钥一致性：TEST
PSK：****************************************************
五、常见报错
1、mysql客户端连接失败：2059-Authentication plugin 'caching_sha2_password' can not be loaded: ...
解决方法：登录数据库后
use mysql
select user,host,plugin,authentication_string from user;
alter user 'USER'@'%' identified with mysql_native_password by 'PASSWORD';
2、zabbix web出现403错误。
vi /etc/httpd/conf
查看ServerName x.x.x.x:80有没有成功添加
3、登录时显示Unable to select configuration.
出现这个错误是数据库表导入失败。删除zabbix库和zabbix用户以后重新执行导入表，创建zabbix库、zabbix用户、导入zabbix数据
SQL> create database zabbix character set utf8 collate utf8_bin;
SQL> create user 'USER'@'%' identified by 'PASSWORD';
SQL> grant all privileges on zabbix.* to 'USER'@'%';
[root]# zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix （过程有一点长，不要中断）
