这个mysql的yum源服务器在国外，所以下载速度会比较慢，mysql5.6只有79M大，而mysql5.7就有182M。
安装mysql57-community-release-el7-11.noarch.rpm包
# yum -y install mysql57-community-release-el7-11.noarch.rpm
[root@localhost ~]# yum -y install mysql57-community-release-el7-.noarch.rpm

进入mysql
# mysql
[root@localhost ~]# mysql
ERROR (): Access denied for user 'root'@'localhost' (using password: NO)
MySQL服务器初始化（从MySQL 5.7开始）：在服务器初始启动时，如果服务器的数据目录为空，则会发生以下情况：
（1）、服务器已初始化
（2）、在数据目录中生成SSL证书和密钥文件
（3）、该validate_password插件安装并启用
（4）、将'root'@'localhost' 创建一个超级用户帐户。设置超级用户的密码并将其存储在日志文件中。要显示它，请使用以下命令：
# grep "password" /var/log/mysqld.log
[root@localhost ~]# grep "password" /var/log/mysqld.log
--10T14::.529782Z [Note] A temporary password is generated for root@localhost: #&kdOvHin6gP
--10T14::.145451Z [Note] Access denied for user 'root'@'localhost' (using password: NO)
使用用户名密码进入mysql
[root@localhost ~]# mysql -uroot -p
Enter password: #输入初始密码

输入初始密码进入mysql数据库，此时不能做任何事情，因为MySQL默认必须修改密码之后才能操作数据库
mysql> show databases;
ERROR (HY000): You must reset your password using ALTER USER statement before executing this statement
修改mysql密码
注意：
MySQL的 validate_password 插件默认安装。这将要求密码包含至少一个大写字母，一个小写字母，一个数字和一个特殊字符，并且密码总长度至少为8个字符。
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '';
ERROR (HY000): Your password does not satisfy the current policy requirements
mysql> SET PASSWORD = PASSWORD('Admin123!');
mysql> SET PASSWORD = PASSWORD('Admin123!');
Query OK, rows affected, warning (0.00 sec)
MySQL完整的初始密码规则可以通过如下命令查看：
mysql> SHOW VARIABLES LIKE 'validate_password%';
mysql> SHOW VARIABLES LIKE 'validate_password%';
+--------------------------------------+--------+
| Variable_name | Value |
+--------------------------------------+--------+
| validate_password_check_user_name | OFF |
| validate_password_dictionary_file | |
| validate_password_length | |
| validate_password_mixed_case_count | |
| validate_password_number_count | |
| validate_password_policy | MEDIUM |
| validate_password_special_char_count | |
+--------------------------------------+--------+
rows in set (0.01 sec)
密码的长度是由validate_password_length决定的，而validate_password_length的计算公式是：
validate_password_length = validate_password_number_count + validate_password_special_char_count + ( * validate_password_mixed_case_count)
如果只想设置简单密码需要修改两个全局参数：
mysql> set global validate_password_policy=0;
mysql> set global validate_password_length=1;
mysql> set global validate_password_policy=;
Query OK, rows affected (0.00 sec) mysql> set global validate_password_length=;
Query OK, rows affected (0.00 sec)
再次查看mysql密码规则
mysql> SHOW VARIABLES LIKE 'validate_password%';
mysql> SHOW VARIABLES LIKE 'validate_password%';
+--------------------------------------+-------+
| Variable_name | Value |
+--------------------------------------+-------+
| validate_password_check_user_name | OFF |
| validate_password_dictionary_file | |
| validate_password_length | |
| validate_password_mixed_case_count | |
| validate_password_number_count | |
| validate_password_policy | LOW |
| validate_password_special_char_count | |
+--------------------------------------+-------+
rows in set (0.00 sec)
此时密码就可以设置的很简单，例如1234之类的
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '';
Query OK, rows affected (0.00 sec)
设置远程可以登录
授权远程登录
grant all privileges on *.* to root@'%' identified by 'password' with grant option;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'IDENTIFIED BY 'password' WITH GRANT OPTION;
第一个是你的用户名root，第二个password是远程的密码
mysql> grant all privileges on *.* to root@'%' identified by '123456' with grant option
flush命令使配置立即生效
mysql> flush privileges;
mysql> select user,host from mysql.user;
+---------------+-----------+
| user | host |
+---------------+-----------+
| mysql.session | localhost |
| mysql.sys | localhost |
| root | localhost |
+---------------+-----------+
rows in set (0.00 sec) mysql> grant all privileges on *.* to root@'%' identified by '' with grant option;
Query OK, rows affected, warning (0.01 sec) mysql> flush privileges;
Query OK, rows affected (0.00 sec) mysql> select user,host from mysql.user;
+---------------+-----------+
| user | host |
+---------------+-----------+
| root | % |
| mysql.session | localhost |
| mysql.sys | localhost |
| root | localhost |
+---------------+-----------+
rows in set (0.00 sec)
或者使用一下语句修改授权远程客户端登录
use mysql;
show tables;
select Host,User from user \G
update user set host = '%' where Host = "localhost" and user = "root";
修改一些简单的配置：
默认的字符集是拉丁字符集，每次创建数据库的时候要设置字符集；默认还不支持group by语句，默认的时区也不是我们现在的北京时间(东八区)，会导致我们的时间差了13个点。
打开配置文件，yum安装的默认在/etc文件夹下：/etc/my.cnf
# vi /etc/my.cnf
默认配置如下：
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html [mysqld]
#
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at % of total RAM for dedicated server, else %.
# innodb_buffer_pool_size = 128M
#
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
#
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock # Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links= log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
在[mysqld]下面添加，不需要分号
字符集:注意是utf8而不是utf-8!
character-set-server=utf8
查看mysql字符集
mysql> show variables like 'char%';
默认字符集如下
mysql> show variables like 'char%';
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
rows in set (0.00 sec)
设置时区为东八区
default-time_zone = '+8:00'
sql支持group by语句
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
