1.下载

先到mysql的官方下载64为的二进制包官方下载

搜狐镜像

2.解压

tar xf mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz

3.移动

mv mysql-5.7.17 /usr/local/mysql

4.标记版本

touch /usr/local/mysql/mysql-5.7.17

5.初始化

./mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/data/mysql
2017-01-07 20:58:11 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize

6.mysql_install_db is deprecated

提示说，不赞成使用mysql_install_db，请使用mysqld --initialize，清空datadir目录，再来mysqld --initialize

7.mysqld --initialize

./mysqld --initialize --initialize-insecure --user=mysql --basedir=/usr/local/mysql/ --datadir=/data/mysql
./mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory

8.error while loading shared libraries: libaio.so.1

yum install libaio -y
./mysqld --initialize --initialize-insecure --user=mysql --basedir=/usr/local/mysql/ --datadir=/data/mysql

9.initialize-insecure

加上这个选项的话，初始化后的mysql是空密码，这样你就不用满大街的找密码了，数据库启动后，记得走一遍mysql_secure_installation，给root加上密码。

步骤整理：

wget http://mirrors.sohu.com/mysql/MySQL-5.7/mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz
tar xf mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz
mv mysql-5.7.17 /usr/local/mysql
touch /usr/local/mysql/mysql-5.7.17
yum install libaio -y
./mysqld --initialize --initialize-insecure --user=mysql --basedir=/usr/local/mysql/ --datadir=/data/mysql
/usr/local/mysql/bin/mysql_secure_installation
