CentOS6.3安装MySQL5.5数据库教程

时间:2014-03-24 01:05来源:Linux社区 作者:IT网
1.下载MySQL
我下载的版本:mysql-5.5.22.tar.gz

下载地址:http://ishare.iask.sina.com.cn/f/24484435.html

2.安装之前先卸载CentOS自带的MySQL
[root@localhost ~]# yum remove mysql

3.编译安装Cmake
下载cmake源码包:http://www.cmake.org/files/v2.8/cmake-2.8.4.tar.gz

从共享目录移至usr目录
[root@localhost ~]# mv /mnt/hgfs/Share-CentOS/cmake-2.8.4.tar.gz /usr/cmake-2.8.4.tar.gz
[root@localhost ~]# cd /usr

解压并安装cmake
[root@localhost usr]# tar xzvf cmake-2.8.4.tar.gz
[root@localhost usr]# cd cmake-2.8.4
[root@localhost cmake-2.8.4]# ./bootstrap

---------------------------------------------
CMake 2.8.4, Copyright 2000-2009 Kitware, Inc.
---------------------------------------------
Error when bootstrapping CMake:
Cannot find appropriate C compiler on this system.
Please specify one using environment variable CC.
See cmake_bootstrap.log for compilers attempted.

---------------------------------------------
Log of errors: /usr/local/src/cmake-2.8.4/Bootstrap.cmk/cmake_bootstrap.log
---------------------------------------------
报错:缺少C的编译器
解决办法:安装gcc编译器
[root@localhost ~]# yum install gcc

继续安装Cmake
[root@localhost cmake-2.8.4]# ./bootstrap

---------------------------------------------
CMake 2.8.4, Copyright 2000-2009 Kitware, Inc.
C compiler on this system is: cc
---------------------------------------------
Error when bootstrapping CMake:
Cannot find appropriate C++ compiler on this system.
Please specify one using environment variable CXX.
See cmake_bootstrap.log for compilers attempted.
---------------------------------------------
Log of errors: /usr/local/src/cmake-2.8.4/Bootstrap.cmk/cmake_bootstrap.log
---------------------------------------------
报错:缺少C++编译器
解决办法:安装gcc-c++编译器
[root@localhost ~]# yum install gcc-c++

再次安装
[root@localhost cmake-2.8.4]# ./bootstrap
没有报错,编译安装
[root@localhost cmake-2.8.4]# gmake
[root@localhost cmake-2.8.4]# gmake install

4.正式开始安装MySQL
添加MySQL用户和用户组
[root@localhost ~]# groupadd mysql
[root@localhost ~]# useradd -g mysql mysql

MySQL源码包从共享文件夹移至/usr并解压
[root@localhost ~]mv /mnt/hgfs/Share-CentOS/mysql-5.5.22.tar.gz /usr/mysql-5.5.22.tar.gz
[root@localhost usr]# tar xzvf mysql-5.5.22.tar.gz
[root@localhost usr]# cd mysql-5.5.22

Cmake运行
[root@localhost mysql-5.5.22]# cmake .

开始编译安装
[root@localhost mysql-5.5.22]# make && make install

进入安装目录,将程序二进制的所有权改为root,数据目录的说有权改为mysql用户,更新授权表
[root@localhost mysql-5.5.22]# cd /usr/local/mysql/
[root@localhost mysql]# chown -R root .
[root@localhost mysql]# chown -R mysql .
[root@localhost mysql]# chgrp -R mysql .
[root@localhost mysql]# scripts/mysql_install_db --user=mysql

安全启动MySQL(默认密码为空)
[root@localhost mysql]#./bin/mysqld_safe --user=mysql&

报错:

120908 00:16:25 mysqld_safe Logging to '/usr/local/mysql/data/CentOS.err'.
120908 00:16:26 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data

解决方法:
[root@CentOS ~]# cd /usr/local/mysql/data

[root@CentOS data]# ls -l

连接本机MySQL
[root@localhost mysql]#mysql –u root –p
提示输入password,默认为空,按Enter即可

断开连接
mysql>exit;

为root账户设置密码
[root@localhost ~]# cd /usr/local/mysql/bin
[root@localhost mysql]# ./bin/mysqladmin -u root password 123456
Enter Password:123456

设置选项文件,将配置文件拷贝到/etc下
[root@localhost mysql]# cp support-files/my-medium.cnf /etc/mysql.cnf

设置开机自启动
[root@localhost mysql]# cp support-files/mysql.server /etc/init.d/mysql
[root@localhost mysql]# chmod +x /etc/init.d/mysql

通过服务来启动和关闭Mysql
[root@localhost ~]# service mysql start
[root@localhost ~]# service mysql stop

5.安装设置完毕,之后使用只需启动-连接-断开-关闭,命令如下:
[root@CentOS mysql]# service mysql start
Starting MySQL..                                           [确定]
[root@CentOS mysql]# mysql -u root -p
Enter password:
