CentOS6.5下添加epel源和安装tomcat7

0.安装yum优先级插件

yum install yum-priorities

1.epel简介: https://fedoraproject.org/wiki/EPEL/zh-cn

rpm -Uvh http://mirrors.ustc.edu.cn/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm

 rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

以上URL请按实际情况修改

2.查看是否安装成功

rpm -q epel-release

 3.导入key：

rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

4.修改/etc/yum.repos.d/epel.repo文件

在[epel]最后添加一条属性 priority=11

vi /etc/yum.repos.d/epel.repo

意思是yum先去官方源查，官方没有再去epel的源找

5.重建缓存

yum makecache

//---------------------------------------------

yum install tomcat tomcat-webapps

chkconfig tomcat on

service tomcat start

http://localhost:8080

vim /etc/tomcat/server.xml

<Context path="" docBase="/var/lib/tomcat/webapps/S3_Service" debug="0" reloadble="false" privileged="true" />

-----

 tomcat无法启动80端口

iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080
