二进制安装mysql方法及其配置

23313

一、实验环境

CentOs 6.6
[iyunv@lnmp02 ~]# uname -rs
Linux 2.6.32-504.el6.i686
[iyunv@lnmp02 ~]#


二、实验步骤


1.从网上下载适合的版本，本文采用mysql-5.5.48-linux2.6-i686，下载地址如下：
    wget   /home/chen/tools http://mirrors.sohu.com/mysql/My ... inux2.6-i686.tar.gz


2.解压并创建软连接文件(解压完相当于编译安装的make && make install完成)

    tar xf  mysql-5.5.48-linux2.6-i686

    mkdir -p /application/mysql  

    mv  mysql-5.5.48-linux2.6-i686  /application/mysql-5.5.48
    ln -s /application/mysql-5.5.48/  /application/mysql


3.创建mysql用户,并不创建家目录和不能登录。

    useradd  mysql  -s /sbin/nologin/ -M

4.切换到/application/mysql下，进行初始化数据库。
    /application/mysql/scripts/mysql_install_db --basedir=/application/mysql --datadir=/application/mysql/data/ --user=mysql

5.授权mysql管理数据库文件
    chown -R mysql.mysql /application/mysql/


6.生成mysql配置文件

    cp  /application/mysql/support-files/mysql-small.cnf   /etc/my.cnf


7.配置启动mysql  

    sed -i 's#/usr/local/mysql#/application/mysql#g' /application/mysql/bin/mysqld_safe


8.配置环境变量(有两种方法，选其中一种)
    vi   /etc/profile  

    PATH="/application/mysql/bin:$PATH"
    source /etc/profile  

或者：cp  /application/mysql/bin/*  /usr/local/sbin/ 出现如下提示即可：
        [iyunv@lnmp02 application]# which mysql
         /usr/local/sbin/mysql


9.登录mysql


[iyunv@lnmp02 application]# mysql
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 2
Server version: 5.5.48 MySQL Community Server (GPL)

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql>


10.设置登录密码和修改密码
   /application/mysql//bin/mysqladmin -u root -password 'new-password'
  /application/mysql//bin/mysqladmin -u root -h lnmp02 password 'new-password'

mysqladmin -uroot password "密码"  ---设置密码
mysqladmin -uroot -pchen password "密码"---修改密码

11.科学的启动方法实现
    cp support-files/mysql.server   /etc/init.d/mysqld  


    sed -i 's#/usr/local/mysql#/application/mysql#g'  /etc/init.d/mysqld


    chmod   +x      /etc/init.d/mysqld   



    chkconfig   mysqld on   


    chkconfig --list mysqld   


完成上诉步骤即可实现二进制安装mysql ^.^  


三、实验总结

其实并不难，只要肯用心，送给所有学习中的小伙伴们，加油！！！
