日常运维中的一键安装或启停脚本
在日常运维中，我们通常会利用shell的"function函数+if逻辑判断+case选择语句"来实现中间件服务一键部署或一键启停。下面分享几个常用运维的一键脚本：
一、Tomcat一键启停服务脚本 [如有多个tomcat实例，就在/etc/init.d/下配置多个针对每个tomcat端口的启停脚本。下面为tomcat_8080脚本文件]
#!/bin/bash
#chkconfig: 345 99 10
#description: Auto-starts tomcat
# /etc/init.d/tomcatd
# Tomcat auto-start
# Source function library.
source /etc/init.d/functions
# source networking configuration.
#. /etc/sysconfig/network
RETVAL=0
project_tomcat=tomcat_8080
#这里的tomcat采用结尾以端口号方式命令。即tomcat_port
#如果本机由多个tomcat示例，则这种结尾以端口号命名的方式比较好，
#执行"echo $JAVA_HOME"可以查看到本机JAVA主目录路径
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.232.b09-0.el7_7.x86_64/
export CATALINA_HOME=/usr/local/${project_tomcat}
#export CATALINA_BASE=/usr/local/${project_tomcat}
#(centos7系统)重新加载服务配置文件。只有当该脚本被修改的时候需要执行该项，可以不配置。
systemctl daemon-reload
#TOMCATUSER=tomcat
start()
{
if [ -f ${CATALINA_HOME}/bin/startup.sh ];
then
echo $"Starting Tomcat"
#这里tomcat使用root启动的，如果不是root用户启动的，这里就修改下用户。
if [ root = `whoami` ];
then
${CATALINA_HOME}/bin/startup.sh
else
su - root -c "${CATALINA_HOME}/bin/startup.sh"
fi
RETVAL=$?
echo " OK"
return ${RETVAL}
fi
}
stop()
{
if [ -f ${CATALINA_HOME}/bin/shutdown.sh ];
then
echo $"Stopping Tomcat"
${CATALINA_HOME}/bin/shutdown.sh
RETVAL=$?
sleep 1
#ps -ef|grep $project_tomcat|egrep -v 'grep|init'|awk '{print$2}'|xargs kill -9
#egrep -v "grep|init" 的过滤效果等同于 grep -v "grep|init"
ps -ef|grep ${project_tomcat}|egrep -v 'grep|init' | grep ${CATALINA_HOME}|awk '{print $2}'|xargs kill -9
#下面可根据自己tomcat日志的实际路径进行更改
mv ${CATALINA_HOME}/logs/catalina.out ${CATALINA_HOME}/logs/catalina.out_`date '+%Y%m%d_%H_%M_%S'`
find ${CATALINA_HOME}/logs/ -mtime +10 -exec rm -rf {} ;
echo " OK"
# [ $RETVAL -eq 0 ] && rm -f /var/lock/...
return ${RETVAL}
fi
}
status()
{
#这里tomcat实例名结尾是以端口号命名的。如果实例名中没有显示端口号，则取tomcat端口号如下：
#port=$(cat ${CATALINA_HOME}/conf/server.xml |grep -w 'URIEncoding="UTF-8"'|awk '{print $2}'|cut -d"=" -f2|cut -d""" -f2)
port=$(echo ${project_tomcat}|awk -F _ '{print$2}')
#打印"lsof -i:port"结果中第二行的第二列,即是该端口所属服务的pid
pid=$(`which lsof` -i:$port|awk 'NR==2{print$2}')
if [ -z $pid ] #判断${pid}字符串是否为空串，空串为真。
then
#使用下面echo方式会将打印内容标红！
echo -e " 33[40;31m${project_tomcat} is stopped 33[0m"
else
echo ${project_tomcat} is running
fi
}
case "$1" in
start)
start
;;
stop)
stop
;;
restart)
echo $"Restaring Tomcat"
stop
sleep 1
start
;;
status)
status
;;
*)
echo $"Usage: $0 {start|stop|restart|status}"
exit 1
;;
esac
exit ${RETVAL}
执行脚本:
[root@localhost ~]# /etc/init.d/tomcat_8080
Usage: /etc/init.d/tomcat_8080 {start|stop|restart|status}
[root@localhost ~]# chmod 755 /etc/init.d/tomcat_8080
[root@localhost ~]# /etc/init.d/tomcat_8080 restart
Restarting tomcat_8080 (via systemctl): [ OK ]
[root@localhost ~]# /etc/init.d/tomcat_8080 status
tomcat_8080 is running
[root@localhost ~]# /etc/init.d/tomcat_8080 stop
Stopping tomcat_8080 (via systemctl): [ OK ]
[root@localhost ~]# /etc/init.d/tomcat_8080 status
tomcat_8080 is stopped
[root@localhost ~]# /etc/init.d/tomcat_8080 start
Starting tomcat_8080 (via systemctl): [ OK ]
[root@localhost ~]# /etc/init.d/tomcat_8080 status
tomcat_8080 is running
二、Zookeeper集群环境一键部署脚本 [生产环境中推荐使用该脚本]
[root@bobo zookeeper]# cat install_zookeeper.sh
#!/bin/bash
source /etc/profile
java -version
if [ "$?" -ne 0 ]; then
echo "JDK未安装，请先安装JDK"
exit 1
fi

执行脚本
需要注意：
上面One_button_install.sh一键部署脚本中涉及服务安装包的下载，考虑到网络因素，可以提前将包下载下来放到指定的${BASE_DIR}目录下，这样有利于提高脚本执行效率。
执行脚本，必须选择安装mysql
[root@localhost ~]# chmod 755 One_button_install.sh
