yum安装mysql5.7

 

 

bash: yum-config-manager: command not found   时候yum -y install yum-utils  

 

Step1: 检测系统是否自带安装mysql

 

# yum list installed | grep mysql

Step2: 删除系统自带的mysql及其依赖
命令：

# yum -y remove mysql-libs.x86_64

Step3: 给CentOS添加rpm源，并且选择较新的源
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:安装mysql 服务器
命令：

# yum install mysql-community-server

Step5: 启动mysql
命令:

# service mysqld start

Step6: 查看mysql是否自启动,并且设置开启自启动
命令:

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

Step7: mysql安全设置
命令：

# mysql_secure_installation

 

5.7.10现在已经不用mysql_secure_installation命令初始化密码了，又保存在临时文件里：/var/log/mysqld.log，可以用grep 'temporary password' /var/log/mysqld.log查找
