mysql在linux下的安装教程

安装环境：系统是 centos6.5

1、下载

下载版本：我这里选择的5.6.33，通用版，linux下64位

2、解压

#解压tar -zxvf mysql-5.6.33-linux-glibc2.5-x86_64.tar.gz#复制解压后的mysql目录cp -r mysql-5.6.33-linux-glibc2.5-x86_64 /usr/local/mysql

3、添加用户组和用户

#添加用户组groupadd mysql#添加用户mysql 到用户组mysqluseradd -g mysql mysql

4、安装

cd /usr/local/mysql/

mkdir ./data/mysqlchown -R mysql:mysql ././scripts/mysql_install_db --user=mysql --datadir=/usr/local/mysql/data/mysqlcp support-files/mysql.server /etc/init.d/mysqldchmod 755 /etc/init.d/mysqldcp 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mysqlservice mysqld start#关闭mysqlservice 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
