书写systemctl配置文件管理tomcat

要使用systemctl管理Tomcat，你需要创建一个名为tomcat.service的服务单元文件。以下是一个基本的示例，假设你的Tomcat安装在/opt/tomcat目录下：

1. 创建一个名为tomcat.service的文件在/etc/systemd/system/目录下。

[Unit]
Description=Tomcat Web Application Container
After=network.target
 
[Service]
Type=forking
 
Environment=JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-amd64
Environment=CATALINA_PID=/opt/tomcat/temp/tomcat.pid
Environment=CATALINA_HOME=/opt/tomcat
Environment=CATALINA_BASE=/opt/tomcat
Environment='CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC'
Environment='JAVA_OPTS=-Djava.awt.headless=true -Djava.security.egd=file:/dev/./urandom'
 
ExecStart=/opt/tomcat/bin/startup.sh
ExecStop=/opt/tomcat/bin/shutdown.sh
 
User=tomcat
Group=tomcat
UMask=0007
RestartSec=10
Restart=always
 
[Install]
WantedBy=multi-user.target

2. 重新加载systemctl配置：

sudo systemctl daemon-reload

3. 启动、停止、启用或禁用Tomcat服务：

sudo systemctl start tomcat
sudo systemctl stop tomcat
sudo systemctl enable tomcat
sudo systemctl disable tomcat

确保替换环境变量中的JAVA_HOME和Tomcat的安装路径/opt/tomcat为你的实际路径。如果你的Tomcat版本或安装路径与上述示例不同，请相应修改配置文件。
