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

或者 wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.33-linux-glibc2.5-x86_64.tar.gz

tar -zxvf mysql-5.6.33-linux-glibc2.5-x86_64.tar.gz

cp -r mysql-5.6.33-linux-glibc2.5-x86_64 /usr/local/mysql

groupadd mysql

useradd -g taizhen mysql

------------

cd /usr/local/mysql

mkdir ./data/mysql

chown -R mysql:mysql ./

./scripts/mysql_install_db --datadir=/usr/local/mysql/data/mysql (这里可能会遇到问题啊)

1.The server quit without updating PID file

这是因为上步执行 db 没有成功。

2.sqld_safe mysqld from pid file /usr/local/mysql/mysql-5.6.33-linux-glibc2.5-x86_6 4/data/mysql/izm5e

yum install -y perl-Module-Install.noarch

3. libaio.so.1: cannot open shared object file

sudo apt-get install libaio1

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<br>source /etc/profile
 
 
#启动mysql
service mysqld start
#关闭mysql
service mysqld stop
#查看运行状态
service mysqld status

mysql 设置root 密码： mysqladmin -u root password

mysql 设置对外可以root访问： GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '这里填你的mysql root 密码' WITH GRANT OPTION;

mysql 一些配置
