Ejabberd2:安装和操作指南(centos yum 安装ejabberd)

（1）首先安装EPEL Repository 

　　    ## RHEL/CentOS 6 32-Bit ##

　　　 # wget http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

　　   # rpm -ivh epel-release-6-8.noarch.rpm

　　   ## RHEL/CentOS 6 64-Bit ##

　　   # wget http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

　　   # rpm -ivh epel-release-6-8.noarch.rpm

（2）什么是EPEL 及 Centos上安装EPEL

　　安装epel,centos6选6，5就选5
　　32位系统选择：
　　　　rpm -ivh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
　　　　rpm -ivh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm
　　64位系统选择：
　　　　rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
　　　　rpm -ivh http://dl.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm
　　导入key：
　　　　rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
　　　　rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-5

　   如果用比较新的软件，用epel-test.repo这个文件就行了
      别忘了安装yum install yum-priorities

（3） yum -y install ejabberd

　　安装完成后配置参考http://blog.163.com/na_llong/blog/static/1135416092013634567224

　　1.{host,["localhost","192.168.xx.xx"]}

　　2.{acl,admin,["user","admin","192.168.xx.xx"]}

　　3.service ejabberd force-reload 

  　　/etc/init.d/ejabberd start|stop|status

　　4.设置密码，下面实例为给admin设置密码为adminxxx

　　　　ejabberdctl register admin 192.168.xx.xx adminxxx

　　--------------------------------------------

　　如果碰到报错

　　Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again

　　则 cd /etc/yum.repos.d/

　　nano epel.repo在第一个epel里面有两种方法：（1）mirrorlist=http去掉s。（2）baseurl去掉#，mirrorlist添加#

　　[epel]
　　name=Extra Packages for Enterprise Linux 6 - $basearch
　　#baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
　　mirrorlist=http://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch

　　[epel]
　　name=Extra Packages for Enterprise Linux 6 - $basearch
　　baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
　　#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch
