目的：
一般二进制安装的tomcat应用是没有配置systemd启动服务的，可以按照需求自行配置使用systemd服务启停tomcat应用会更加的方便。
一、配置Tomcat应用service服务
bash
# 复制粘贴以下内容完成配置tomcat的systemd启停服务
cat > /etc/systemd/system/tomcat.service << EOF
[Unit]
Description=Apache Tomcat Web Application Container
After=syslog.target network.target
[Service]
Type=forking
# 设置 JAVA 环境变量，修改为你的 JAVA_HOME 目录
Environment=JAVA_HOME=/usr/local/jdk1.8.0_161
# 设置 tomcat 应用pid文件
# Environment=CATALINA_PID=/opt/tomcat/temp/tomcat.pid
# tomcat 应用安装目录, 修改成你的 tomcat 安装目录
Environment=CATALINA_HOME=/opt/tomcat
Environment=CATALINA_BASE=/opt/tomcat
# 设置 JVM 参数，不建议直接在这里设置，可以在 bin目录下的 setenv.sh 文件配置jvm等相关参数
# Environment='CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC'
# tomcat 启动命令，修改成你的启动命令的实际绝对路径
ExecStart=/opt/tomcat/bin/startup.sh
# tomcat 停止命令，修改成你的停止命令的实际绝对路径
ExecStop=/opt/tomcat/bin/shutdown.sh
# 运行用户,正常情况是使用非 root 用户,如 tomcat 用户
User=root
Group=root
UMask=0007
# 异常则自动尝试重启
RestartSec=10
Restart=always
[Install]
WantedBy=multi-user.target
EOF
# 重新加载 systemd
systemctl daemon-reload
# 启动 tomcat
systemctl start tomcat
# 停止 tomcat
systemctl stop tomcat
# 查看 tomcat 运行状态
systemctl status tomcat二、演示例子
bash
[root@lighthouse ~]#
[root@lighthouse ~]# # 查看tomcat的service配置信息
[root@lighthouse ~]# cat /etc/systemd/system/tomcat.service
