Mysql5.6.36 script compilation and installation and initialization tutorial, mysql5.6.36 Initialization

Overview

This document describes how to automatically compile and install the script of mysql5.3.6 for centos7.3 and subsequent initialization operations.

The installation script install. py is as follows:

# Coding = UTF-8 #! /Usr/bin/pythonimport OS, commands # defines the variable install_dir = '/data/mysql' data _ dir ='/data/mysql/data' package _ dir = '/data/mysql' log _ dir = '/ data/mysql/logs' current _ dir = OS. getcwd () cmake = 'cmake-DCMAKE_INSTALL_PREFIX = % s-DMYSQL_UNIX_ADDR = % s/mysql. sock-DDEFAULT_CHARSET = utf8-DDEFAULT_COLLATION = utf8_general_ci-DMYSQL_DATADIR = % s-Limit = 3306 '% (install_dir, install_dir, data_dir) # Install the dependency package OS. system ('Yum install gcc-c ++ gcc-g77 autoconf automake zlib * fiex * libxml * ncurses-devel libmcrypt * libtool-ltdl-devel * make cmake perl-y ') # Install function def install_mysql (): if OS. system ('groupadd mysql') = 0: print 'group mysql add success!

Usage:

1. Configure the yum source for the operating system
2. operating system version: centos7.3
3. Put the install. py my. cnf and mysql installation packages in a folder.

Initialization

By default, mysql5.6.36 compiled and installed does not have a password. You can directly enter mysql in the command line to log on and execute the following SQL statement.

-- Initialize data use mysql; update user set password = PASSWORD ("Abcd123") where user = 'root'; grant all privileges on *. * to weihu @ "%" identified by "Abcd123"; delete from mysql. user where user = ''; flush privileges; -- CREATE a demo database create database 'Demo' default character set utf8 COLLATE utf8_general_ci; show databases;
