CentOS7中，将tomcat8配置为系统服务配置，可以使用systemctl直接启动

修改tomcat的catalina.sh文件， 在152行左右 添加如下内容：

CATALINA_PID="$CATALINA_BASE/tomcat.pid"

# 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"
CATALINA_PID="$CATALINA_BASE/tomcat.pid"
# Ensure that any user defined CLASSPATH variables are not used on startup,
# but allow them to be specified in setenv.sh, in rare case when it is needed.

然后在/usr/lib/systemd/system下面建立tomcat.service文件

vim /usr/lib/systemd/system/tomcat.service

内容如下：

[Unit]
