分享一个由systemd管理tomcat的tomcat.service文件的编写

如果你有一个tomcat的二进制包你就可以使用以下.service文件直接套用，前提是你必须先停止现有的tomcat

cat tomcat.service

[Unit]
Description=tomcat server daemon   # 描述
After=syslog.target network.target remote-fs.target nss-lookup.target	# 在那些服务之后启动
 
[Service] 
Type=forking  
 
Environment='JAVA_HOME=/usr/lib/jvm/java-11-openjdk-11.0.22.0.7-1.el7_9.x86_64'		
Environment='CATALINA_PID=/var/run/tomcat.pid'	# 文件需要创建
Environment='CATALINA_HOME=/root/apache-tomcat-9.0.88'
Environment='CATALINA_BASE=/root/apache-tomcat-9.0.88'
Environment='CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC'
 
WorkingDirectory=/root/apache-tomcat-9.0.88
 
PIDFile=/var/run/tomcat.pid
 
ExecStart=/root/apache-tomcat-9.0.88/bin/startup.sh
ExecReload=/root/apache-tomcat-9.0.88/bin/catalina.sh restart
ExecStop=/root/apache-tomcat-9.0.88/bin/catalina.sh stop
PrivateTmp=true
 
[Install]
WantedBy=multi-user.target

# 移动到系统读取.service 的目录
mv tomcat.service /usr/lib/systemd/system/
# 重新加载
systemctl daemon-reload

# 创建pid文件
touch /var/run/tomcat.pid
# 启动并自启
systemctl enable tomcat --now
