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：wgethttp://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.33-linux-glibc2.5-x86_64.tar.gz
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
4#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
cpsupport-files/mysql.server/etc/init.d/mysqld
chmod755/etc/init.d/mysqld
cpsupport-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
exportPATH=$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
