linux下安装mysql环境

1.在安装apache的时候已经检查了本地没有安装centos自带的mysql，有的话一定要卸载掉，否则可能占用端口

2.准备mysql安装包（注意编译的时候，mysql5.5版本以上的编译和5.5一下的编译是不同的，5.5要用cake编译，但是cake系统6.5没有，需自己下载）

3.准备安装包xftp上传（上传前我先递归删除了apache的安装后的无用包，省的碍事）

4.卸载原有的5.1版本

rpm -qa | grep -i mysql 发现有自带的mysql 5.1版本（太低了，需卸载，现在主流的公司都在5.5版本及以上：主要会和5.5package冲突）

    whereis mysql  
    rpm -qa | grep -i mysql  
    service mysql stop  
    find / -name mysql  
    rm -rf /usr/lib64/mysql  
    rm -rf /usr/share/mysql/  

    rpm -qa | grep -i mysql  
    rpm -ev mysql-libs-5.1.73-3.el6_5.x86_64   --nodeps

6.开始解压包
