本文實例講述了centos6.7安裝mysql5.5.48的方法。分享給大家供大家參考，具體如下：

RPM安裝mysql 5.5.48

下載對應的MySQL安裝包rpm文件，可以去MySQL官方網站找到對應版本，一般需要下載3個文件

MySQL-server
MySQL-client
MySQL-devel

復制代碼代碼如下:

		wget http://dev.mysql.com/get/Downloads/MySQL-5.5/MySQL-server-5.5.48-1.el6.x86_64.rpm
		wget http://dev.mysql.com/get/Downloads/MySQL-5.5/MySQL-client-5.5.48-1.el6.x86_64.rpm
		wget http://dev.mysql.com/get/Downloads/MySQL-5.5/MySQL-devel-5.5.48-1.el6.x86_64.rpm
		rpm -ivh MySQL-server-5.5.48-1.el6.x86_64.rpm
		rpm -ivh MySQL-client-5.5.48-1.el6.x86_64.rpm
		rpm -ivh MySQL-devel-5.5.48-1.el6.x86_64.rpm

安裝服務端出錯：

復制代碼代碼如下:

		[root@localhost ~]# rpm -ivh MySQL-server-5.5.48-1.el6.x86_64.rpm
		warning: MySQL-server-5.5.48-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

錯誤原因：包沖突了

centos6.7 basic server 版本默認安裝了mysql5.1，所以先卸載mysql5.1

復制代碼代碼如下:

yum -y remove mysql-libs-5.1*

再重新安裝即可

復制代碼代碼如下:

rpm -ivh MySQL-server-5.5.48-1.el6.x86_64.rpm

啟動mysql

復制代碼代碼如下:

		[root@localhost ~]# service mysql start
		Starting MySQL SUCCESS!

CentOS下安裝官方RPM包的MySQL后找不到my.cnf解決辦法

復制 /usr/share/mysql/my-medium.cnf 文件到/etc目錄，

復制代碼代碼如下:

cp /usr/share/mysql/my-medium.cnf /etc/my.cnf

局域網內mysql連接慢的解決辦法

ping都很快，mysql連接慢，

原因是由于mysql對連接的客戶端進行DNS反向解析。

有2種解決辦法：

1. 把client的ip寫在mysql服務器的/etc/hosts文件里，隨便給個名字就可以了。
2. 在 my.cnf 中加入 –skip-name-resolve 。

希望本文所述對大家centos服務器配置有所幫助。
