Linux（Centos7） 配置 Tomcat 开机自启

1.解压tomcat

去官网下载好源码压缩包之后，解压到自己的路径下，一般是 /usr/local/ 目录下。

2.添加环境变量

vim打开 /etc/profile 文件，在末尾添加：

export CATALINA_HOME=/usr/local/tomcat
export CLASSPATH=.:${JAVA_HOME}/lib:${CATALINA_HOME}/lib
export PATH=$PATH:${CATALINA_HOME}/bin

注意更改你的 tomcat 安装路径

3.添加服务脚本

在 /usr/lib/systemd/system/ 路径下，新建 tomcat.service文件，写入如下代码：

[Unit]
Description=Tomcat
After=syslog.target network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
PIDFile=/opt/softWare/apache-tomcat-7.0.57/tomcat.pid
ExecStart=/opt/softWare/apache-tomcat-7.0.57/bin/startup.sh
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true

[Install]
WantedBy=multi-user.target

4.启动服务

systemctl daemon-reload

systemctl start tomcat.service

5.异常处理

如果报以下异常

# systemctl start tomcat.service  
Job for tomcat.service failed because the control process exited with error code.
 See "systemctl status tomcat.service" and "journalctl -xe" for details.

并且经过检查$JAVA_HOME 和$JRE_HOME都是正常的。

解决办法

在tomcat/bin/catalina.sh 中添加jdk环境:

export JAVA_HOME=/usr/local/jdk1.8.0_281/
export JRE_HOME=/usr/local/jdk1.8.0_281/jre

6.启动tomcat.service

# systemctl start tomcat.service  启动tomcat
# systemctl status tomcat.service  启动并查看详细启动信息
# systemctl restart tomcat.service  重启tomcat
# systemctl stop tomcat.service  关闭tomcat
# systemctl enable tomcat.service 开机自启
# systemctl disable tomcat.service 禁用开机自启
