今天在CentOS下安裝MySQL，從MySQL官網下載了rpm安裝包，但是安裝server時怎麼也不成功，每次都出現大量的“file /usr/share/mysql/portuguese/errmsg.sys from install of MySQL-server-community-5.1.73-1.rhel5.x86_64 conflicts with file from package mysql-libs-5.1.61-4.el6.x86_64”提示，就沒有反應，仔細看了看提示才發現是系統原有的MySQL沒有卸載乾淨。
其實網上的安裝方法說得很清楚，首先使用“rpm -qa | grep mysql”查看是否有遺留的安裝組件，但通常網上直說要卸載server和client，我這裏顯示的是mysql-lib，以爲沒有影響，我的錯誤就在這裏。這一步只要你要安裝的版本和已有版本不同就必須全部卸載已有組件，不僅限於server和client。卸載以後再使用"rpm
-ivh MySQL-server-community-5.1.73-1.rhel5.x86_64.rpm"就很正常了。
出錯提示如下：
[root@client setup]# rpm -ivh MySQL-server-community-5.1.73-1.rhel5.x86_64.rpm
