安装环境

系统是 centos6.5

1、下载

下载地址：http://dev.mysql.com/downloads/mysql/5.6.html#downloads

下载版本：我这里选择的5.6.33，通用版，linux下64位

也可以直接复制64位的下载地址，通过命令下载：wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.33-linux-glibc2.5-x86_64.tar.gz

2、解压

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mysql

useradd -g mysql mysql

4、安装

cd /usr/local/mysql/

mkdir ./data/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

#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
