案例

[root@server /opt/apache-tomcat-icbc/logs]# du -sh catalina.out
210M    catalina.out

解决

# 1. 安装cronolog
[root@server ~]#yum –y install cronolog
[root@server ~]# which cronolog
/usr/sbin/cronolog

# 2. 修改bin/catalina.sh

    # 1. 找到下面行并把它用#注释掉
    touch "$CATALINA_OUT"

    # 2. 替换下面的行(有两处，不过一般在 -security 中的那一行不需要去关注，不妨两处全替换了)
    >> "$CATALINA_OUT" 2>&1 "&"
    替换为
    2>&1 |/usr/sbin/cronolog "$CATALINA_BASE/logs/catalina-%Y-%m-%d.out" &

# 3. 重启tomcat
[root@server /opt/apache-tomcat-icbc/bin]#sh shutdown.sh
[root@server /opt/apache-tomcat-icbc/bin]#sh startup.sh
