從別人哪兒考到的mysql安裝過程

Step1: 檢測系統是否自帶安裝mysql

# yum list installed | grep mysql
Step2: 刪除系統自帶的mysql及其依賴
命令：

# yum -y remove mysql-libs.x86_64
Step3: 給CentOS添加rpm源，而且選擇較新的源
命令：

# wget dev.mysql.com/get/mysql-community-release-el6-5.noarch.rpm
# yum localinstall mysql-community-release-el6-5.noarch.rpm
# yum repolist all | grep mysql
# yum-config-manager --disable mysql55-community
# yum-config-manager --disable mysql56-community
# yum-config-manager --enable mysql57-community-dmr
# yum repolist enabled | grep mysql
Step4:安裝mysql 服務器
命令：

# yum install mysql-community-server
Step5: 啓動mysql
命令:

# service mysqld start
Step6: 查看mysql是否自啓動,而且設置開啓自啓動
命令:

# chkconfig --list | grep mysqld
# chkconfig mysqld on
