tomcat_无痕分割catalina.out日志文件

• 定义启动tomcat启动脚本

[test@test  bin]$ cd /home/test/apache-tomcat-8.5.100/bin
[test@test  bin]$ more start_tomcat.sh 
#!/bin/bash
start(){
    echo "Starting tomcat"
    bash startup.sh
    nohup ./tomcat_log.sh > /dev/null 2>&1 &
    echo $?
}

stop(){
    echo "Stopping tomcat..."
    pid_num=$(ps -ef|grep $(whoami)|grep apache-tomcat-8.5.100|grep -v grep|awk '{print $2}')
    log_num=$(ps -ef|grep $(whoami)|grep tomcat_log.sh|grep -v grep|awk '{print $2}')
    if [[ $pid_num =~ ^[0-9]+$ ]];then
        kill -9 $pid_num
    fi

    if [[ $log_num =~ ^[0-9]+$ ]];then
        kill -9  $log_num
    fi
    echo $?
}

case "$1" in
    start)
        start
        ;;
    stop)
        stop
        ;;
    restart)
        stop
        start
        ;;
    *)
        echo "Usage: $0 {start|stop|restart}"
        exit 1
        ;;
esac

exit 0

• tomcat日志分割脚本，定义凌晨00点执行

[test@test bin]$ more tomcat_log.sh 
#!/bin/bash

tomcat_log_split(){
    # 定义变量
    CATALINA_OUT="../logs/catalina.out"
    BACKUP_DIR="../logs"
    DATE=$(date +%Y-%m-%d_%H_%S)
    # 检查备份目录是否存在，不存在则创建
    if [ ! -d "$BACKUP_DIR" ]; then
        mkdir -p "$BACKUP_DIR"
    fi
    # 备份并压缩当前的 catalina.out 文件
    tar zcf "${BACKUP_DIR}/catalina.out_${DATE}.tar.gz" "$CATALINA_OUT"
    # 创建一个新的空的 catalina.out 文件
    truncate -s0 "$CATALINA_OUT"
}

HourArray=(17)
while true; do
    RunTime=$(date +%H)
    if [[ " ${HourArray[*]} " =~ " ${RunTime} " ]]; then
        tomcat_log_split
        # 计算距离下一个整点的时间并睡眠相应秒数
        sleep $((3600 - $(date +%M%S)))
    fi
    # 计算距离下一个整点的时间并睡眠相应秒数
    sleep $((3600 - $(date +%M%S)))
done
