Mysql5.6.36脚本编译安装及初始化教程
了不起的大航神 人气:0这篇文章主要为大家详细介绍了Mysql5.6.36脚本编译安装及初始化的相关代码，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
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/python
import 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;
