centos7设置tomcat8开机自动启动

1.前提是你已经安装好了tomcat服务。
2.配置Tomcat开机启动很简单，将Tomcat配置为系统服务并配置为开机启动即可。
首先将tomcat配置为系统服务：
创建tomcat8服务文件：

[root@ftpserver bin]# vim /usr/lib/systemd/system/tomcat.service 
[Unit]
Description=Tomcat
After=syslog.target network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
Environment="JAVA_HOME=/usr/java/jdk1.8.0_181-cloudera"
Environment="CATALINA_HOME=/usr/tomcat/apache-tomcat-8.5.39"
Environment="CATALINA_BASE=/usr/tomcat/apache-tomcat-8.5.39"
Environment='CATALINA_PID=/usr/tomcat/apache-tomcat-8.5.39/bin/tomcat.pid'
Environment='CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC'

WorkingDirectory=/usr/tomcat/apache-tomcat-8.5.39
ExecStart=/usr/tomcat/apache-tomcat-8.5.39/bin/startup.sh
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true

[Install]
WantedBy=multi-user.target

3.接下来配置tomcat开机启动：
设置tomcat开机启动：systemctl enable tomcat
启动tomcat服务：systemctl start tomcat
查看服务中有没有tomcat：ps -ef |grep tomcat
