Uninstall MariaDB

CentOS7 installs MariaDB by default instead of MySQL, and MySQL-related software packages are also removed from the yum server. Because MariaDB and MySQL may conflict, uninstall MariaDB first.

1. Before installing the new version of mysql, we need to uninstall the mariadb-lib that comes with the system

[root@iZwz94qazh62gk5ewl4ei2Z home]# rpm -qa | grep -i mariadb
mariadb- libs-5.5.52-1.el7.x86_64
[root@iZwz94qazh62gk5ewl4ei2Z home]# rpm -e --nodeps mariadb-libs-5.5.52-1.el7.x86_64

2 , Go to the official website of mysql to download the latest version of mysql rpm collection package: mysql-5.7.18-1.el6.x86_64.rpm-bundle.tar

3, upload mysql-5.7.18-1.el6. x86_64.rpm-bundle.tar to the linux server, and decompress the tar package

[root@iZwz94qazh62gk5ewl4ei2Z home]# mkdir mysql
[root@iZwz94qazh62gk5ewl4ei2Z home]# tar -xf mysql-5.7.18-1.el6.x86_64.rpm-bundle.tar -C mysql
[root@iZwz94qazh62gk5ewl4ei2Z home]# cd mysql
[root@iZwz94qazh62gk5ewl4ei2Z mysql]# ll

[root@iZwz94qazh62gk5ewl4ei2Z mysql]#

Copy after login

The above packages have dependencies, execute There is a sequence.

Use the rpm installation method to install mysql. The installation path is as follows:

a 数据库目录
/var/lib/mysql/
b 配置文件
/usr/share/mysql(mysql.server命令及配置文件)
c 相关命令
/usr/bin(mysqladmin mysqldump等命令)
d 启动脚本
/etc/rc.d/init.d/(启动脚本文件mysql的目录)
e /etc/my.conf

Copy after login

5. Database initialization

In order to ensure that the database directory is the owner of the file and the mysql login user, If your Linux system is running the mysql service as root, you need to execute the following command to initialize

[root@iZwz94qazh62gk5ewl4ei2Z mysql]# mysqld --initialize --user=mysql

Copy after login

If you are logged in and run as mysql, you can remove the --user option.

In addition, the --initialize option defaults to initialization in "safe" mode, which will generate a password for the root user and mark the password as expired. After logging in, you need to set a new password,

When using the --initialize-insecure command, the safe mode is not used and a password will not be generated for the root user.

The --initialize initialization used in the demonstration here will generate a root account password. The password is in the log file. The red area is the automatically generated password.

[root@iZwz94qazh62gk5ewl4ei2Z mysql]# cat /var/log/mysqld.log
