安装：

make
make install
chown -R mysql.mysql /usr/local/alisql/
echo never > /sys/kernel/mm/transparent_hugepage/enabled

初始化数据：

chmod +x ./scripts/mysql_install_db
./scripts/mysql_install_db  --user=mysql  --basedir=/usr/local/alisql --datadir=/usr/local/alisql/data

vi /etc/my.cnf   #加入以下内容

拷贝启动项：

cp  support-files/mysql.server  /etc/init.d/mysqld

环境变量配置:
vi  /etc/profile #加入以下

PATH=/usr/local/alisql/bin:/usr/local/alisql/lib:$PATH
export PATH

source /etc/profile

软链接：

ln -s /usr/local/alisql/bin/mysql /usr/bin

启动并设置开机启动：

chmod +x /etc/init.d/mysqld
service mysqld start
chkconfig --level 35 mysqld on

查看是否启动：

netstat -tulnp | grep 3306
mysql -u root -p    #默认root密码为空

#授权新密码

mysqladmin -uroot  -p  password 123456   

#运行后按提示输入一次确定密码即可（这里是123456）

mysql -uroot -p           #重新登录
