1、安裝：

安裝客戶端

sudo yum install mysql

安裝服務器

sudo yum install mysql-server

2、配置：查看配置文件

cat /etc/my.cnf

3、啟動：

啟動腳本：cat /etc/init.d/mysqld

sudo service mysqld start/stop/status/restart/reload/force-reload/condrestart

?

初次啟動信息：多了啟動初始化的一些工作

Initializing MySQL database:? WARNING: The host '10-57-19-59' could not be looked up with resolveip.
This probably means that your libc libraries are not 100 % compatible
with this binary MySQL version. The MySQL daemon, mysqld, should work
normally with the exception that host name resolving will not work.
This means that you should use IP addresses instead of hostnames
when specifying MySQL privileges !
Installing MySQL system tables...
OK
Filling help tables...
OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h 10-57-19-59 password 'new-password'

Alternatively you can run:
/usr/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.? This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd /usr/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /usr/bin/mysqlbug script!

Starting mysqld:?????????????????????????????????????????? [? OK? ]

未初始化前，mysql -h127.0.0.1 -uroot登錄后的表如下，root賬號都默認密碼為空

執行如下命令進行安裝設置：

sudo mysql_secure_installation

設置root密碼，禁止遠程用戶使用root賬號登錄，刪除測試表test，刪除匿名用戶，重新設置表的權限

重新設置密碼：password 'root'為新密碼；-proot為舊密碼

sudo mysqladmin -u root -h127.0.0.1? -proot? password 'root'

?

把在所有數據庫的所有表的所有權限賦值給位于所有IP地址的root用戶。

mysql> grant all privileges on *.* to root@'%' identified by 'password';

如果是新用戶而不是root，則要先新建用戶

mysql>create user 'username'@'%' identified by 'password';

此時就可以進行遠程連接了。
