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!

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;
