Record the process of installing MySQL 5.6.37 in CentOS 6.9 environment for your reference.

If centos7 + system: Need to uninstall rpm -e mariadb-libs-5.5.52-1.el7.x86_64 --nodeps

1. Prepare the file system for data storage

Create a new logical volume and mount it to a specific directory. The process is no longer given here.

Assume that the logical volume mount directory is/data, and then you need to create the/data/mysqldata directory as the mysql data storage directory.

[root@centos /]# mkdir -p /data/mysqldata

2. Create a new user to run the process in a secure manner:

[root@centos ~]# useradd mysql -s /sbin/nologin -M

[root@centos ~]# chown -R mysql:mysql /data/mysqldata

Install and initialize mysql

[root@centos ~]# wget https://cdn.mysql.com//Downloads/MySQL-5.6/mysql-5.6.37-linux-glibc2.12-x86_64.tar.gz

[root@centos ~]# tar -xf mysql-5.6.37-linux-glibc2.12-x86_64.tar.gz -C /usr/local/src/

[root@centos ~]# cd /usr/local/

[root@centos local]# ln -sv /usr/local/src/mysql-5.6.37-linux-glibc2.12-x86_64/ mysql #modify according to actual situation

[root@centos local]# cd mysql

[root@centos mysql]# chown -R mysql:mysql .

4. Provide the main configuration file for mysql: #After initialization, there will be my.cnf under/etc by default. If there is content deletion overwrite, you can

profile

[root@centos mysql]# yum install libaio* libnuma* -y #install dependencies

[root@centos mysql]# vim /etc/my.cnf

[root@centos mysql]# scripts/mysql_install_db --user=mysql --datadir=/data/mysqldata/

[root@centos mysql]# chown -R root .

5. Provide sysv service scripts for mysql:

[root@centos mysql]# cd /usr/local/mysql

[root@centos mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysqld

[root@ccentos mysql]# ldconfig

6. Modify PATH environment variable so that system can directly use mysql related commands.

[root@centos mysql]# echo "PATH=$PATH:/usr/local/mysql/bin" > /etc/profile.d/mysql.sh

[root@centos mysql]# source /etc/profile.d/mysql.sh

7. Last startup service added boot startup

[root@centos mysql]# service mysqld start

[root@centos mysql]# chkconfig mysqld on

[root@centos mysql]# cd /usr/local/mysql/bin

[root@centos bin]# ./ mysqladmin -u root password '123456'

[root@centos bin]# mysql -uroot -p123456
