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
- ● tomcat7.service - 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
- 正在连接 localhost (localhost)|::1|:8080... 已连接。
