分布式架构2--CentOs下安装Tomcat7（环境准备）

声明：因为运行环境是基于Linux系统的，在做此框架之前需要做一些前期的环境准备工作
CentOs下安装Tomcat7网上很多实例，因为博客后期作为框架的原生教程，故这边做详细的安装记录，我这边已经下载好了Tomcat7，通过ssh已经上传到指定的目录，这里直接讲解安装的过程。

1. 安装tomcat
通过ssh将apache-tomcat-7.0.61.tar.gz文件上传到/usr/local中执行以下操作：       

[root@cloud  /]cd /usr/local

[root@cloud  /]tar -zxvfapache-tomcat-7.0.61.tar.gz

[root@cloud  /]mv apache-tomcat-7.0.61 tomcat

2. 启动Tomcat
[root@cloud ~]# /usr/local/tomcat/bin/startup.sh
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /home/Java/jdk1.7/
Using CLASSPATH:      /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.
出现以上信息说明已成功启动。

3. 防火墙开放8080端口
[root@cloud  /]vi + /etc/sysconfig/iptables 

#增加以下代码
#Tomcat 8080
-A INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT

4. 重启防火墙
[root@cloud  /]service iptables restart 

5. 检验Tomcat安装运行，通过你自己的服务器IP查看tomcat是否运行正常：
http://xxx.xxx.xxx.xxx:8080/
看到tomcat系统界面，说明安装成功！

6. 停止Tomcat

[root@cloud ~]#/usr/local/tomcat/bin/shutdown.sh 
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /home/java/jdk1.7
Using CLASSPATH:      /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar

7. 查看启动、停止日志

[root@cloud ~]#cd /usr/local/tomcat/logs/
[root@cloud logs]# ls
catalina.2016-02-13.log  catalina.out                host-manager.2016-02-14.log localhost.2016-02-14.log            localhost_access_log.2016-02-14.txt  manager.2016-02-14.log

[root@cloud logs]# tail -f catalina.out
