[root@localhost MysqL]#
PS:MysqL5.7新特性：由上面可以看出， MysqL_install_db 已经不再推荐使用了，建议改成 MysqLd --initialize 完成实例初始化。
加入MysqL为系统服务:
[root@localhost MysqL]# cp support-files/MysqL.server /etc/init.d/MysqLd
[root@localhost MysqL]# chkconfig MysqLd on
[root@localhost MysqL]# chkconfig --list|grep MysqLd
MysqLd 0:off 1:off 2:on 3:on 4:on 5:on 6:off
[root@localhost MysqL]#chmod 755 /etc/init.d/MysqLd
MysqL服务启动、重启、停止
[root@localhost MysqL]# serivce MysqLd start
[root@localhost MysqL]# serivce MysqLd stop
[root@localhost MysqL]# serivce MysqLd restart
[root@localhost MysqL]#
设置环境变量:
[root@localhost MysqL]# vim /etc/profile
export PATH=/usr/local/MysqL/bin:$PATH
[root@localhost MysqL]#
检查MysqL是否能开启
[root@localhost MysqL]# cd /usr/local/MysqL
[root@localhost MysqL]# cd support-files/
[root@localhost support-files]# ./MysqL.server start
Starting MysqL.. SUCCESS!
若改用了， 则在启动服务时会出现如下错误：
# ./support-files/MysqL.server start
./support-files/MysqL.server: line 276: cd: /usr/local/MysqL: No such file or directory
Starting MysqL ERROR! Couldn't find MysqL server (/usr/local/MysqL/bin/MysqLd_safe)
这时候我们需要修改/support-files/MysqL.server文件的basedir和datadir目录路径为我们正确的MysqL的basedir和datadir路径， 如下：
# vim support-files/MysqL.server
--------------------------
...
basedir=/usr/local/MysqL
datadir=/data/MysqL/data
# ./support-files/MysqL.server start
Starting MysqL.. SUCCESS!
创建配置文件
将默认生成的my.cnf备份
# mv /etc/my.cnf /etc/my.cnf.bak
[root@localhost support-files]# cp my-default.cnf /etc/my.cnf
先将MysqL服务停止
# service MysqLd stop
进入MysqL安装目录， 执行：
# cd /usr/local/MysqL
# ./bin/MysqLd_safe --skip-grant-tables --skip-networking&

另外打开一个终端(p.s. 如果是ssh连接登录的,另外创建一个ssh连接即可）， 执行操作如下：

到此， 设置完MysqL用户root的密码且确保MysqL编码集是utf8,注意上面， 新版本的MysqL.user表里的密码字段是authentication_string
MysqL远程授权
格式如下：
MysqL> grant all [privileges] on db_name.table_name to 'username'@'host' identified by 'password';
示例如下：
MysqL> grant all privileges on *.* to 'root'@'%' identified by '123456';
Query OK,0 rows affected,1 warning (0.04 sec)
MysqL> FLUSH PRIVILEGES;
Query OK,0 rows affected (0.00 sec)
或用
MysqL> grant all on *.* to 'root'@'%' identified by '123456';
到此， 完成了MysqL的安装 及配置！！！
