linux下安装mysql

(1)先安装cmake（mysql5.5以后是通过cmake来编译的）

[root@ rhel5 local]#tar -zxv -f cmake-2.8.4.tar.gz
[root@ rhel5 local]#cd cmake-2.8.4
[root@ rhel5 cmake-2.8.4]#./configure
[root@ rhel5 cmake-2.8.4]#make
[root@ rhel5 cmake-2.8.4]#make install

(2)安装mysql

[root@ rhel5 local]#tar -zxv -f mysql-5.5.10.tar.gz

    

     

      [root@ rhel5 local]
      #
      cd mysql-5.5.10
       [root@ rhel5 mysql-5.5.10]
      #
      cmake .  [root@ rhel5 mysql-5.5.10]
      #
      make
       [root@ rhel5 mysql-5.5.10]
      #
      make install 
     
    

(3)创建系统数据库的表

[root@ rhel5 mysql]# cd /usr/local/mysql
[root@ rhel5 mysql]# scripts/mysql_install_db --user=mysql

(6）将mysql添加到服务
 
[root@ rhel5 mysql]# cp support-files/mysql.server  /etc/init.d/mysql　//将mysql的启动服务添加到系统服务中

(4)设置环境变量

   


    
[root@ rhel5~]# vi /root/.bash_profile

在PATH=$PATH:$HOME/bin添加参数为：

PATH=$PATH:$HOME/bin:/usr/local/mysql/bin:/usr/local/mysql/lib

[root@ rhel5~]#source /root/.bash_profile

   

(5)手动启动mysql
   


    
[root@ rhel5~]# cd /usr/local/mysql

[root@ rhel5 mysql]# ./bin/mysqld_safe --user=mysql & 　 //启动MySQL，但不能停止

启动日志写在此文件下：/usr/local/mysql/data/localhost.err

关闭MySQL服务

[root@ rhel5 mysql]# mysqladmin -u root -p shutdown　　//这里MySQL的root用户还没有配置密码，所以为空值。需要输入密码时，直接点回车键即可。

   

(7)修改MySQL的root用户的密码以及打开远程连接

   


    

     [root@ rhel5~]
     #
      mysql -u root mysql
       mysql>use mysql; mysql>desc user; mysql> GRANT ALL PRIVILEGES ON *.* TO root@
     "
     %
     " IDENTIFIED BY 
     "
     root
     ";　　//为root添加远程连接的能力。 mysql>update user set Password = password('xxxxxx') where User='root'; mysql>select Host,User,Password from user where User='root'; mysql>flush privileges; mysql>exit 重新登录：mysql -u root -p 若还不能进行远程连接，则关闭防火墙 [root@ rhel5~]
     #
      /etc/rc.d/init.d/iptables stop
