Label:

The CentOS7 Yum source does not seem to have MySQL by default. To solve this problem, we need to download the MySQL repo source first.

1. Download the MySQL repo source

$ wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm

2. Install the MYSQL-COMMUNITY-RELEASE-EL7-5.NOARCH.RPM package

$ sudo rpm-ivh mysql-community-release-el7-5.noarch.rpm

After installing this package, you will get two MySQL yum repo Source:/etc/yum.repos.d/mysql-community.repo,/etc/yum.repos.d/mysql-community-source.repo.

3. Install MySQL

$ sudo yum install Mysql-server

Follow the steps to install it, but after the installation is complete, there is no password and you need to reset the password.

4. Reset Password

Before resetting your password, you must first log in

$ mysql-u Root

This error may be reported at login: Error 2002 (HY000): Can ' t connect to local MySQL server through socket '/var/lib/mysql/mysql.sock ' (2) because/var /lib/mysql access rights issues. The following command changes the owner of the/var/lib/mysql to the current user:

$ sudo chown-r openscanner:openscanner/var/lib/mysql

Then, restart the service:

$ Service Mysqld Restart

Next login to reset Password:

$ mysql-u Root

MySQL > Use mysql;mysql > Update user set Password=password (' 123456 ') where user= ' root '; mysql > exit;

5. Open 3306 Ports

$ sudo vim/etc/sysconfig/iptables

Add the following content:

-A input-p tcp-m state--state new-m TCP--dport 3306-j ACCEPT

Restart the firewall after saving:

$ sudo service iptables restart

This allows the MySQL service to be connected from other clients as well.
