Tomcat服务重启与日志清理脚本

Tomcat服务重启脚本

#此脚本适用于本地安装tomcat环境，操作脚本重启。

[root@ansible_clent ~]# cat restart_tomcat.sh 
#!/bin/bash
function shutdown_tomcat () {
    #tomcat_id=`jps | grep Bootstrap | awk '{print $1}'`
tomcat_id=`lsof -i:8080 | awk 'NR==2''{print $2}'`
if [ ! $tomcat_id ];then
echo "tomcat process in ${ip} is not exist."
else
echo "shoutdown ${ip} tomcat"
/bin/kill -9 $tomcat_id
fi
}
function start_tomcat () {
echo "start $ip tomcat"
/bin/sh /data/tomcat/bin/catalina.sh start
/usr/local/java/bin/jps
}
function restart_tomcat () {
shutdown_tomcat
start_tomcat
}
restart_tomcat

#此脚本限于在跳板机上使用操作Tomcat重启服务(机器之间做了ssh密钥认证)

[root@ansible_clent ~]# cat restart_tomcat.sh 
#!/bin/sh
cat <<EOF

重启某些ip的tomcat服务,ip地址以,隔开

Tomcat 日志清理小脚本

#查看磁盘的大小和输出格式：

$ df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/vda1        20G  5.8G  13G  31% /
tmpfs          1.9G    0  1.9G  0% /dev/shm
/dev/vdb        40G  12G  26G  32% /data

#截取/data目录使用磁盘大小的百分比

$ max=`df -h |awk 'NR==4''{print $5 }'| cut -d% -f1`
$ echo $max
32

#创建清除日志的脚本

cat clean_log.sh
#!/bin/bash
max=`df -h |awk 'NR==4''{print $5 }'| cut -d% -f1`
if [ "$max" -gt 75 ];then
    echo " " > /data/tomcat/logs/catalina.out
    find /data/tomcat/logs/ -type f -name "*.log" -mtime +5 | xargs rm -rf
    find /data/tomcat/logs/ -type f -name "localhost_*.txt" -mtime +7 |xargs rm -rf
fi

#创建计划任务，每1小时运行脚本1次

$ crontab -l
0 * * * * /bin/sh /data/clean_log.sh
