# linux-tomcat以服务管理 #

> centos7 jkd8 tomcat9为例

#### 1、安装jdk tomcat(步骤略) ####

> tomcat安装路径  
> /usr/local/apache-tomcat-9.0.40

#### 2、配置service ####

> 进入路径/usr/lib/systemd/system，创建一个以.service结尾的文件，例如tomcat9.service  
> vim tomcat9.service

[Unit]
    Description=tomcat9
    After=syslog.target network.target remote-fs.target nss-lookup.target
    
    [Service]
    Type=forking
    ExecStart=/usr/local/apache-tomcat-9.0.40/bin/startup.sh
    ExecStop=/usr/local/apache-tomcat-9.0.40/bin//shutdown.sh
    ExecReload=/bin/kill -s HUP $MAINPID
    RemainAfterExit=yes
    
    [Install]
    WantedBy=multi-user.target

> 在上述配置文件中，我们需要注意的是配置好ExecStart和ExecStop  
> ExecStart对应的是tomcat的启动脚本  
> ExecStop对应的是tomcat的停止脚本

#### 使用systemctl控制服务 ####

> \#查看服务状态  
> systemctl status tomcat9

> \#设置tomcat开机自启动  
> systemctl enable tomcat9

Created symlink from /etc/systemd/system/multi-user.target.wants/tomcat9.service to /usr/lib/systemd/system/tomcat9.service.

> \#关闭tomcat开机自启动  
> systemctl disable tomcat9

Removed symlink /etc/systemd/system/multi-user.target.wants/tomcat9.service.
