概述

本文为centos7.3自动化编译安装mysql5.3.6的脚本及后续初始化操作，话不多少，直接上脚本。

安装脚本install.py如下：

#coding=utf-8#!/usr/bin/pythonimport os,commands#定义变量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 -DMYSQL_TCP_PORT=3306' % (install_dir, install_dir, data_dir)#安装依赖包os.system('yum install gcc gcc-c++ gcc-g77 autoconf automake zlib* fiex* libxml* ncurses-devel libmcrypt* libtool-ltdl-devel* make cmake perl -y')#安装函数def install_mysql(): if os.system('groupadd mysql') == 0: print 'group mysql add success!' else: exit('group mysql add failed!') if os.system('useradd -r -g mysql -s /bin/false mysql') == 0: print 'user mysql add success!' else: exit('user mysql add failed!') if not os.path.exists(install_dir): os.system('mkdir -p %s' % install_dir) if not os.path.exists(data_dir): os.system('mkdir -p %s' % data_dir) if not os.path.exists(package_dir): os.system('mkdir -p %s' % package_dir) if not os.path.exists(log_dir): os.system('mkdir -p %s' % log_dir) if os.system('tar zxvf mysql-5.6.36.tar.gz') == 0: print 'uncompress v success!' else: exit('uncompress mysql-5.6.36.tar.gz failed!') os.chdir('mysql-5.6.36') if os.system(cmake) == 0: print '编译成功' else: exit('编译mysql失败') if os.system('make && make install') == 0: print '编译安装mysql成功' else: exit('编译安装mysql失败') if os.system('chown -R mysql:mysql %s' % install_dir) == 0: print '安装目录权限配置成功' else: exit() os.system('chown -R mysql:mysql %s' % data_dir) os.system('cd %s && touch mysql-error.log' % log_dir) os.system('chown -R mysql:mysql %s' % log_dir) os.chdir(install_dir) if os.system('./scripts/mysql_install_db --user=mysql --datadir=%s' % data_dir) == 0: print 'mysql初始化成功' else: exit('mysql初始化失败') os.system('cp support-files/mysql.server /etc/init.d/mysqld') os.system('mv /etc/my.cnf /etc/my.cnf.bak') os.chdir(current_dir) os.system('cp my.cnf /etc/my.cnf') os.system('service mysqld start') os.system('chkconfig mysqld on')install_mysql()if os.path.exists('/etc/profile'): os.system('cp /etc/profile /etc/profile.bak')if os.system('echo "PATH=%s/bin:%s/lib:$PATH" >> /etc/profile' % (install_dir, install_dir)) == 0: print '修改/etc/profile成功'else: exit()if os.system('echo "export PATH" >> /etc/profile') == 0: print '修改/etc/profile文件成功'else: exit()

配置文件my.cnf

使用方法：

1.操作系统需要配置yum源
2.操作系统版本：centos7.3
3.将install.py my.cnf 和mysql安装包放一个文件夹

初始化

由于默认情况下编译安装的mysql5.6.36没有密码，命令行直接输入mysql进行登陆，执行以下sql语句

-- 初始化数据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;-- 创建demo数据库CREATE DATABASE `demo` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;show databases;
