Installing mysql-5.6.37 on CentOS 6.9

Installing mysql-5.6.37 on CentOS 6.9

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.

This assumes that the mounted directory of its logical volume is/data, and then needs to create the/data/mysqldata directory as the storage directory for MySQL data.

[Email protected]/]# mkdir-p/data/mysqldata

2. The new user runs the process in a secure manner:

[Email protected] ~]# useradd mysql-s/sbin/nologin-m

[Email protected] ~]# chown-r mysql:mysql/data/mysqldata

3. Installation and initialization of MySQL

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

[Email protected] ~]# TAR-XF mysql-5.6.37-linux-glibc2.12-x86_64.tar.gz-c/usr/local/src/

[Email protected] ~]# cd/usr/local/

[email protected] local]# Ln-sv/usr/local/src/mysql-5.6.37-linux-glibc2.12-x86_64/mysql #根据实际情况修改

[[Email protected] local]# CD MySQL

[Email protected] mysql]# chown-r mysql:mysql.

4. Provide the main configuration file for MySQL: #默认初始化后会在/etc has my.cnf, if you have content to delete the overlay can

[Email protected] mysql]# scripts/mysql_install_db--user=mysql--datadir=/data/mysqldata/

[Email protected] mysql]# chown-r root.

5. Provide SYSV service script for MySQL:

[Email protected] mysql]# Cd/usr/local/mysql

[email protected] mysql]# CP support-files/mysql.server/etc/rc.d/init.d/mysqld

[Email protected] mysql]# Ldconfig

6, modify the PATH environment variable, so that the system can directly use MySQL related commands.

[Email protected] mysql]# echo "path= $PATH:/usr/local/mysql/bin" >/etc/profile.d/mysql.sh
[Email protected] mysql]# source/etc/profile.d/mysql.sh

7. Finally start the service add boot

[[Email protected] mysql]# service mysqld start

[Email protected] mysql]# chkconfig mysqld on

[Email protected] bin]#/mysqladmin-u root password ' 123456 '

[Email protected] bin]# mysql-uroot-p123456
