理论知识怱略，马上开始实战
一、首先准备好tomcat 启动、关闭、重启Shell脚本：
以下Shell脚本主要修改值
tomcatPath：tomcat目录
runUser:以哪个身份运行
此处测试的Shell脚本存放地址如下：
mkdir /usr/local/apache-tomcat-7.0.94/sbin/
vi /usr/local/apache-tomcat-7.0.94/sbin/tomcat-server
#复制tomcat-server的代码
chmod +x /usr/local/apache-tomcat-7.0.94/sbin/tomcat-server
#!/bin/bash #Authtor : suk #Date : 20180428 #Email : 277667028@qq.com . /etc/init.d/functions #Result Code RETVAL=0 #Tomcat Pid TomcatPid=null #Tomcat Home tomcatPath=/usr/local/application/apache-tomcat-7.0.65 runUser=‘tomcat‘ getTomcatPid() { TomcatPid=$(ps -ef | grep java |grep tomcat | grep -w $tomcatPath | grep -v ‘grep ‘ | awk ‘{print $2}‘) } checkTocamtPid() { getTomcatPid if [ -n "$TomcatPid" ]; then #run RETVAL=1 else #no run RETVAL=0 fi } start() { checkTocamtPid if [ $RETVAL -eq 1 ]; then getTomcatPid action "Tomcat Already Running Pid:【$TomcatPid】" /bin/false exit $RETVAL else /bin/sudo su - $runUser $tomcatPath/bin/startup.sh getTomcatPid action "Start Tomcat Success Pid:【$TomcatPid】" /bin/true fi } restart() { checkTocamtPid if [ $RETVAL -eq 1 ]; then stop sleep 1 fi start } stop() { checkTocamtPid if [ $RETVAL -eq 1 ]; then getTomcatPid /bin/kill -9 $TomcatPid action "Stop Tomcat PID:【$TomcatPid】" /bin/true else action "Tomcat Status No Running" /bin/false fi } #Check Tomcat Status status() { checkTocamtPid [ $RETVAL -eq 1 ] && echo "Tomcat is Running Pid:【$TomcatPid】" || echo "No Tomcat Running" } #Check Tomcat Start Logs logs(){ logsPath=$tomcatPath/logs/catalina.out if [ ! -f $logsPath ];then echo "$logsPath Not Eixts" else /usr/bin/tail -f $logsPath exit $RETVAL fi } case "$1" in start) start ;; stop) stop ;; restart) restart ;; status) status ;; logs) logs ;; *) echo $"Usage: $0 {start|stop|restart|status|logs}" esac
二、创建运行用户,这里以用户名：tomcat 为例
useradd tomcat
三、把tomcat目录权授
chown -R tomcat.tomcat /usr/local/apache-tomcat-7.0.94
注意：
程序用到的所有目录都需要授权给该用户,否则会报权限不足，导致执行失败，执行命令同上
四、开始编写systemctl启动的配置文件
vi /lib/systemd/system/tomcat.service [Unit] Description=Tomcat server daemon Documentation=/data/application/apache-tomcat-8.5.38 #注意：一般tomcat服务都是在数据库或redis等启动之后，再运行，确保数据库或redis有制作systemctl，在配置到After，mysql.service redisd.service名字是编写systemctl时的文件名 After=network.target mysql.service redisd.service [Service] Type=forking PIDFile=/usr/local/apache-tomcat-7.0.94/tomcat.pid ExecStart=/usr/local/apache-tomcat-7.0.94/sbin/tomcat-server start ExecStop=/usr/local/apache-tomcat-7.0.94/sbin/tomcat-server stop Restart=/usr/local/apache-tomcat-7.0.94/sbin/tomcat-server restart PrivateTmp=True [Install] WantedBy=multi-user.target
5、配置Tomcat Pid生产的位置
注意：
确认Tomcat PID必须 与 /lib/systemd/system/tomcat.service 配置里面的 PIDFile 保持一致
vi /usr/local/apache-tomcat-7.0.94/bin/catalina.sh 怱略 # # USE_NOHUP (Optional) If set to the string true the start command will # use nohup so that the Tomcat process will ignore any hangup # signals. Default is "false" unless running on HP-UX in which # case the default is "true" # ----------------------------------------------------------------------------- CATALINA_PID=/usr/local/apache-tomcat-7.0.94/tomcat.pid # OS specific support. $var _must_ be set to either true or false. cygwin=false 怱略
6、刷新systemctl配置
#重新加载配置文件 systemctl daemon-reload #服务开启，关闭，重启 systemctl start tomcat.service systemctl stop tomcat.service systemctl restart tomcat.service #设置开机自动启动 systemctl enable tomcat.service
注意：
启动完成后，需要检查进程是否运行
ps -ef | grep java
正常启动如下：
