操作系统CentOS,apache2.2.4,数据库Mysql-5.0.18。使用mysql源码包进行安装,也可以使用mysql二进制包安装或者rpm包安装。

操作系统CentOS,apache2.2.4,,数据库Mysql-5.0.18。使用mysql源码包进行安装,也可以使用mysql二进制包安装或者rpm包安装。

1。增加一个登录用户和群组:

    # groupadd mysql

    #useradd -g mysql mysql

2。解压mysql-5.0.18.tar.gz到/usr/local/mysql

   #tar -zvxf mysql-5.0.18,tar.gz

3。进入mysql-5.0.18目录

  #cd mysql-5.0.18

4。运行configure编译mysql源码

  #./configure --prefix=/usr/local/mysql/

5。安装mysql到指定的目录

  #make;make install

6。把/support-files/my-medium.cnf复制到/etc/下

  #cp ./support-files/my-medium.cnf /etc/my.cnf

7。在还没有安装mysql数据库之前,还必须为mysql建立授权表:

  #/scripts/mysql_install_db --user=mysql&

注:也可以使用root,但是--user须改为-user

8。修改相应文件的权限(/usr/local/mysql/)

  #chown -R root /usr/local/mysql

  #chown -R mysql /usr/local/mysql

  #chown -R mysql /usr/local/mysql/var

9。启动mysql:(/usr/local/mysql/)

  # ./bin/mysqld_safe --user=mysql&

10。安装后mysql数据库的root帐户密码默认为空,可以这样修改:

  # /usr/local/mysql/bin/mysqladmin -u root -password 'new-password'

11。把mysql命令加入到环境变量

  # echo "export PATH=$PATH:/usr/local/mysql/bin">>/etc/profile

  #source /etc/profile         //使环境变量生效

  #echo $PATH                         //输出环境变量

/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/root/bin:/usr/local/mysql/bin
 

12。开机时启动mysql,把mysql.server放到开机启动的文件中/etc/init.d/mysql:(/usr/local/src/目录下)

  #cp ./mysql-5.0.18/support-fiels/mysql.server /etc/init.d/mysql

  #chkconfig --add mysql

  #chkconfig mysql on

13。登录mysql:(必须把mysql命令加入到环境变量中)

  # mysql -u root -p12345
