cd /usr/local/mysql/

chown -R mysql:mysql ./

./scripts/mysql_install_db --user=mysql --datadir=/usr/local/mysql/data/mysql

cp support-files/mysql.server /etc/init.d/mysqld

chmod 755 /etc/init.d/mysqld

cp support-files/my-default.cnf /etc/my.cnf

 

#修改启动脚本

vi /etc/init.d/mysqld

 

#修改项:

basedir=/usr/local/mysql/

datadir=/usr/local/mysql/data/mysql

 

#启动服务

service mysqld start

 

#测试连接

./mysql/bin/mysql -uroot

 

#加入环境变量,编辑 /etc/profile,这样可以在任何地方用mysql命令了

export PATH=$PATH:/usr/local/mysql//bin
source /etc/profile

 

 

#启动mysql

service mysqld start

#关闭mysql

service mysqld stop

#查看运行状态

service mysqld status

5、错误

  5.1 sqlyog连接时,报1130错误,是由于没有给远程连接的用户权限问题

    解决1:更改 ‘mysql’数据库‘user’表‘host’项,从‘localhost’改成‘%’。

use mysql;
select 'host' from user where user='root'; 
update user set host = '%' where user ='root';
flush privileges; 

    解决2:直接授权

      GRANT ALL PRIVILEGES ON *.* TO ‘root’@'%’ IDENTIFIED BY ‘youpassword’ WITH GRANT OPTION;

  5.2 安装时的一些错误

    -bash: ./scripts/mysql_install_db: /usr/bin/perl: bad interpreter: 没有那个文件或目录
    解决: yum -y install perl perl-devel

    Installing MySQL system tables..../bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
    解决:yum -y install libaio-devel

6、其他

  6.1 配置环境变量

    vi + /etc/profile

    export PATH=....:/usr/local/mysql/bin
