yum 安装mysql

步骤：

1、sudo rpm -Uvh http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm

2、yum install mysql mysql-server mysql-libs

这两个步骤可能会遇到的错误。

第一个步骤可能出现这样的错误：

curl: (35) SSL connect error
error: skipping http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm - transfer failed

解决方法：

yum -y update nss

第二个步骤可能出现这样的错误：

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

解决的办法：

vi /etc/yum.repos.d/mysql-community.repo 

在其中：

找到mysql-56-community
将enable置为0 enable=0

如下图。

 

安装完成过后，我们可以使用命令：service mysqld status

来查看mysql的运行情况，一般刚安完后，得到的结果为：

mysqld is stopped

那么我们就要启动mysql：service mysqld start

然后我们在查看一下mysql的运行状态。

得到一下结果，代表启动成功。

mysqld (pid 2641) is running...

到这里mysql就算是安装成功了。

利用命令登录mysql： mysql -u root -p

 

[root@node1 ~]# mysql -u root -p
Enter password:
