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

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

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

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
