第一种方法：yum 安装cronolog软件 1.yum install cronolog -y 第三方软件 源码包下载地址id=3457&ResourceID=1851 2.修改配置文件。修改前记得备份 [root@tomcat01 sbin]# cat -n /aliyun/tomcat7/bin/catalina.sh 184 #if [ -z "$CATALINA_OUT" ] ; then 185 # CATALINA_OUT="$CATALINA_BASE"/logs/catalina.out 186 #fi 改为下面的 187 ################### 188 if [ -z "$CATALINA_OUT" ] ; then 189 CATALINA_OUT="$CATALINA_BASE"/logs/tomcat01.$(date +%F).out 190 fi 191 ##################### 注释掉373 #touch "$CATALINA_OUT" 386 387 改为一下： 386 org.apache.catalina.startup.Bootstrap "$@" start 2>&1
387 | /usr/local/sbin/cronolog "$CATALINA_OUT" >> /dev/null & 395 396 改为一下： 395 org.apache.catalina.startup.Bootstrap "$@" start 2>&1
396 | /usr/local/sbin/cronolog "$CATALINA_OUT" >> /dev/null & 注意此两处修改不要注视，注释启动tomcat时会报错。要直接删掉这两处的原内容

[root@tomcat01 logs]# /aliyun/tomcat7/bin/startup.sh 报错：/usr/local/sbin/ 没有cronolog
[root@tomcat01 logs]# cp /usr/sbin/cronolog /usr/local/sbin/ /aliyun/tomcat7/bin/startup.sh (成功) 如果抱错catalina.sh,说明此脚本文件没有执行权限,所以 chown +x catalina.sh 3.区分不同的tomcat机器的日志方便集中收集tomcat实时日志 [root@tomcat01 logs]# vim /aliyun/tomcat7/bin/catalina.sh 188 if [ -z "$CATALINA_OUT" ] ; then 189 ATALINA_OUT="$CATALINA_BASE"/logs/ tomcat01.$(date +%F).out 190 fi /aliyun/tomcat7/bin/startup.sh [root@tomcat01 logs]# find ./ -type f -name "tomcat01.2016-04-22.out" ./tomcat1.2016-04-22.out

[root@tomcat01 logs]# vim /aliyun/tomcat7/bin/catalina.sh 188 if [ -z "$CATALINA_OUT" ] ; then 189 ATALINA_OUT="$CATALINA_BASE"/logs/ tomcat01.$(date +%F).out 190 fi /aliyun/tomcat7/bin/startup.sh [root@tomcat01 logs]# find ./ -type f -name "tomcat01.2016-04-22.out" ./tomcat01.2016-04-22.out

第二种方法源码包编译安装cronolog第三方tomcat日志切割软件 1.源码包下载地址 http:///download.php?id=3457&ResourceID=1851 2.安装过程 cd /aliyun/soft/ rz -y cronolog-1.6.2.tar.gz ls tar xf cronolog-1.6.2.tar.gz -C /aliyun/ cd /aliyun/cronolog-1.6.2/ ./configure echo $? make && make install echo $? [root@tomcat02 sbin]# ll /usr/local/sbin/ total 52 -rwxr-xr-x 1 root root 40438 May 12 09:15 cronolog -rwxr-xr-x 1 root root 9673 May 12 09:15 cronosplit 到此处编译安装完成 3.编辑文件按天切割日志 vim /aliyun/tomcat7/bin/catalina.sh

[root@tomcat01 sbin]# cat -n /aliyun/tomcat7/bin/catalina.sh 184 #if [ -z "$CATALINA_OUT" ] ; then 185 # CATALINA_OUT="$CATALINA_BASE"/logs/catalina.out 186 #fi 改为下面的 187 ################### 188 if [ -z "$CATALINA_OUT" ] ; then 189 CATALINA_OUT="$CATALINA_BASE"/logs/tomcat01.$(date +%F).out 190 fi 191 ##################### 注释掉373 #touch "$CATALINA_OUT" 386 387 改为一下： 386 org.apache.catalina.startup.Bootstrap "$@" start 2>&1
387 | /usr/local/sbin/cronolog "$CATALINA_OUT" >> /dev/null & 395 396 改为一下： 395 org.apache.catalina.startup.Bootstrap "$@" start 2>&1
396 | /usr/local/sbin/cronolog "$CATALINA_OUT" >> /dev/null & 注意此两处修改不要注视，注释启动tomcat时会报错。要直接删掉这两处的原内容 4.重新启动tomcat生效 [root@tomcat02 sbin]# ll /aliyun/tomcat7/logs/ total 0 [root@tomcat02 sbin]# /etc/init.d/tomcat7 stop tomcat7 service is stopped! [ OK ] [root@tomcat02 sbin]# ll /aliyun/tomcat7/logs/ total 0 [root@tomcat02 sbin]# /etc/init.d/tomcat7 start tomcat7 service is starting! [ OK ] [root@tomcat02 sbin]# ll /aliyun/tomcat7/logs/ total 16 -rw-r--r-- 1 root root 4295 May 12 09:34 catalina.2016-05-12.log -rw-r--r-- 1 root root 0 May 12 09:34 localhost.2016-05-12.log -rw-r--r-- 1 root root 0 May 12 09:34 localhost_access_log.2016-05-12.txt -rw-r--r-- 1 root root 4295 May 12 09:34 tomcat02.2016-05-12.out
