centos7 使用systemctl设置tomcat9服务

CentOS7开始，从/etc/init.d脚本改为了systemctl管理服务。
本文记录了把tomcat9加入systemd管理的步骤。

1.首先，需要为tomcat配置pid。

# cd /usr/local/tomcat//usr/local/tomcat/apache-tomcat-9.0.21/bin

# ls

 

编辑 catalina.sh脚本文件

# vim catalina.sh

 

# Get standard environment variables
PRGDIR=`dirname "$PRG"`

# Only set CATALINA_HOME if not already set
[ -z "$CATALINA_HOME" ] && CATALINA_HOME=`cd "$PRGDIR/.." >/dev/null; pwd`

# Copy CATALINA_BASE from CATALINA_HOME if not already set
[ -z "$CATALINA_BASE" ] && CATALINA_BASE="$CATALINA_HOME"

#添加的pid
# setting tomcat.pid
CATALINA_PID="$CATALINA_BASE/tomcat.pid"

 

2.创建tomcat.service文件

# cd /usr/lib/systemd/system

# vim tomcat.service

文件内容

3.修改tomcat.service文件后需要执行下面命令使其生效：

# systemctl daemon-reload

 

启动tomcat服务

systemctl start tomcat.service

 

设置开机自启动

systemctl enable tomcat.service

停止开机自启动

systemctl disable tomcat.service

查看服务当前状态

systemctl status tomcat.service

重新启动服务

systemctl restart tomcat.service

查看所有已启动的服务

systemctl list-units --type=service
