设置权限：

chown -R mysql:mysql /usr/local/mysql

初始化MySQL，留意临时密码：

cd /usr/local/mysql/bin
./mysqld --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data/ --initialize

配置启动脚本：

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

启动MySQL服务、添加到开机启动项

service mysqld start  或者  /etc/init.d/mysqld start
chkconfig mysqld on 或者  systemctl enable mysqld.service

查看临时密码：

cat  /usr/local/mysql/mysql-error.log |grep 'A temporary password'

登录，并修改密码：

cd /usr/local/mysql/bin
./mysql -u root -p
set password for root@localhost = password('123456');
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;
FLUSH PRIVILEGES;

配置环境变量：

vim /root/.bash_profile
PATH=$PATH:$HOME/bin:/usr/local/mysql/bin

立即生效：

source /root/.bash_profile
