CentOS 7 安装 Tomcat 7.0

1. 解压tomcat

[root@ruijie packages]# tar -zxvf apache-tomcat-7.0.85.tar.gz -C /opt/

2. 修改tomcat文件夹名

[root@ruijie opt]# mv apache-tomcat-7.0.85/ tomcat7

3. 配置tomcat环境变量

[root@ruijie bin]# vi /etc/profile

# 设置tomcat环境变量
export TOMCAT_HOME=/opt/tomcat7
export CATALINA_HOME=/opt/tomcat7
export PATH=$PATH:$TOMCAT_HOME/bin

4. 刷新profile文件

[root@ruijie bin]# source /etc/profile

5. 修改tomcat默认端口

[root@ruijie bin]# vi /opt/tomcat7/conf/server.xml

直接输入/8080检索：

<Connector port="80" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

6. 启动tomcat

[root@ruijie bin]# cd /opt/tomcat7/bin/
[root@ruijie bin]# sh startup.sh
Using CATALINA_BASE:   /opt/tomcat7
Using CATALINA_HOME:   /opt/tomcat7
Using CATALINA_TMPDIR: /opt/tomcat7/temp
Using JRE_HOME:        /opt/jdk8/jre
Using CLASSPATH:       /opt/tomcat7/bin/bootstrap.jar:/opt/tomcat7/bin/tomcat-juli.jar
Tomcat started.

7. 验证Tomcat是否启动成功

8. 查看当前开放的端口

[root@ruijie bin]# firewall-cmd --zone=public --list-ports

9. 开放80端口

[root@ruijie ~]# firewall-cmd --zone=public --add-port=80/tcp --permanent

10. 刷新防火墙规则

[root@ruijie bin]# firewall-cmd --reload
success

11. 再次查看开放的端口

[root@ruijie bin]# firewall-cmd --zone=public --list-ports
80/tcp

12. 重新启动tomcat并验证

13. OK!!!
