centos7设置tomcat7为系统服务的方法

1，准备工作：

JKD：jdk-7u72-Linux-x64.gz

Tomcat：apache-tomcat-7.0.70.tar.gz

OS：CentOS linux release 7.2.1511 (Core) 

2，安装jdk

A，解压jdk在 /usr/ 目录下

B， root用户配置全局环境变量，

vi /etc/profile
追加以下内容
export JAVA_HOME=/usr/jdk1.7.0_72
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

生效：source /etc/profile

3，安装tomcat7

A，解压tomcat至 /usr/目录下

B，在/usr/lib/systemd/system/目录下新建文件tomcat7.service，内容如下：

[Unit]
Description=Tomcat7
After=syslog.target network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
Environment='JAVA_HOME=/usr/jdk1.7.0_72'
Environment='CATALINA_PID=/usr/apache-tomcat-7.0.70/bin/tomcat.pid'
Environment='CATALINA_HOME=/usr/apache-tomcat-7.0.70/'
Environment='CATALINA_BASE=/usr/apache-tomcat-7.0.70/'
Environment='CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC'

WorkingDirectory=/usr/apache-tomcat-7.0.70/

ExecStart=/usr/apache-tomcat-7.0.70/bin/startup.sh
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true

[Install]
WantedBy=multi-user.target

C，设置为开启机启动：systemctl enable tomcat7

4，启停服务

A,启动服务：systemctl start tomcat7

B,停止服务：systemctl stop tomcat7

C,重启服务：systemctl restart tomcat7

检查状态：systemctl status tomcat7

运行的状态：

[root@localhost merrick]# systemctl status tomcat7

5，测试服务

浏览器中输入 : http://ip:8080/

检查服务器能正确响应。

或者终端命令行输入: wget htp://localhost:8080/

正常响应：

[root@localhost merrick]# wget http://localhost:8080/
--2016-09-08 11:54:47--  http://localhost:8080/
正在解析主机 localhost (localhost)... ::1, 127.0.0.1
