Centos7.x版本下针对Mysql的安装和使用多少跟之前的Centos6之前版本有所不同的，废话就不多赘述了，下面介绍下在centos7.x环境里安装mysql5.7的几种方法：一、yum方式安装从CentOS 7.0发布以来，yum源中开始使用Mariadb来代替MySQL的安装。即使你输入的是yum install -y mysql , 显示的也是Mariadb的安装内容。使用源代码进行编译安装又太麻烦。因此，如果想使用yum安装MySQL的话，就需要去下载官方指定的yum源.yum下载网址为：https://dev.mysql.com/downloads/repo/yum/找到Red Hat Enterprise Linux 7 / Oracle Linux 7 (Architecture Independent), RPM Package，单击后面的Download，在新的页面中单击最下面的No thanks, just start my download.就可以下载到yum源了。1）安装MySQL YUM资源库[root@kevin ~]# yum localinstall https://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm 2）安装MySQL 5.7[root@kevin ~]# yum install -y mysql-community-server 3）启动MySQL服务器和MySQL的自动启动[root@kevin ~]# systemctl start mysqld.service[root@kevin ~]# systemctl enable mysqld.service 4）密码问题由于MySQL从5.7开始不允许首次安装后使用空密码进行登录！为了加强安全性，系统会随机生成一个密码以供管理员首次登录使用，这个密码记录在/var/log/mysqld.log文件中，使用下面的命令可以查看此密码：[root@kevin ~]# cat /var/log/mysqld.log|grep ‘A temporary password‘2018-01-24T02:32:20.210903Z 1 [Note] A temporary password is generated for root@localhost: DOqInortw9/< 最后一行冒号后面的部分DOqInortw9/<就是初始密码。使用此密码登录MySQL:[root@kevin ~]# mysql -pEnter password:Welcome to the MySQL monitor. Commands end with ; or \g.Your MySQL connection id is 4Server version: 5.7.21 Copyright (c) 2000, 2018, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or itsaffiliates. Other names may be trademarks of their respectiveowners. Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement. 使用随机生产的密码登录到服务端后，必须马上修改密码，不然会报如下错误：mysql> show databases;ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement. 有两种方法解决上面的报错（如下的123456是修改后的密码）：mysql> set password=password("123456");或者mysql> alter user ‘root‘@‘localhost‘ identified by ‘123456‘; 刷新权限mysql> flush privileges; ===============================================================================================如果上面在执行set password=password("123456");命令后出现下面的报错：ERROR 1819 (HY000): Your password does not satisfy the current policy requirements 解决办法：这个与Mysql 密码安全策略validate_password_policy的值有关，validate_password_policy可以取0、1、2三个值：0 or LOW Length1 or MEDIUM Length; numeric, lowercase/uppercase, and special characters2 or STRONG Length; numeric, lowercase/uppercase, and special characters; dictionary 默认的数值是1，符合长度，且必须含有数字，小写或大写字母，特殊字符。所以刚开始设置的密码必须符合长度，且必须含有数字，小写或大写字母，特殊字符。 有时候，只是为了自己测试，不想密码设置得那么复杂，譬如说，我只想设置root的密码为123456。必须修改两个全局参数：mysql> set global validate_password_policy=0;Query OK, 0 rows affected (0.00 sec) mysql> set global validate_password_length=1;Query OK, 0 rows affected (0.00 sec) 修改上面两个参数后，就可以解决这个报错了。======================================================================================================= 注意一点：mysql5.7之后的数据库里mysql.user表里已经没有password这个字段了，password字段改成了authentication_string。所以修改密码的命令如下： mysql> update mysql.user set authentication_string=password(‘kevin@123‘) where user=‘root‘;Query OK, 1 row affected, 1 warning (0.00 sec)Rows matched: 1 Changed: 1 Warnings: 1 mysql> flush privileges;Query OK, 0 rows affected (0.00 sec) mysql> =======================================================================================================查看mysql版本mysql> select version();+-----------+| version() |+-----------+| 5.7.21 |+-----------+1 row in set (0.00 sec)mysql>=======================================================================================================修改mysql5.7的编码由latin1为utf8 默认编码：mysql> show variables like "%character%";show variables like "%collation%";+--------------------------+----------------------------+| 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/ |+--------------------------+----------------------------+8 rows in set (0.00 sec) +----------------------+-------------------+| Variable_name | Value |+----------------------+-------------------+| collation_connection | utf8_general_ci || collation_database | latin1_swedish_ci || collation_server | latin1_swedish_ci |+----------------------+-------------------+3 rows in set (0.01 sec) 调整操作：[root@kevin ~]# cat /etc/my.cnf......[mysqld]......character-set-server=utf8 //注意这个不能写成default-character-set=utf8，否则会导致5.7版本mysql无法打开 [client]default-character-set=utf8 [root@kevin~]# systemctl restart mysqld.service[root@kevin~]# mysql -p......mysql> show variables like "%character%";show variables like "%collation%";+--------------------------+----------------------------+| Variable_name | Value |+--------------------------+----------------------------+| character_set_client | utf8 || character_set_connection | utf8 || character_set_database | utf8 || character_set_filesystem | binary || character_set_results | utf8 || character_set_server | utf8 || character_set_system | utf8 || character_sets_dir | /usr/share/mysql/charsets/ |+--------------------------+----------------------------+8 rows in set (0.01 sec) +----------------------+-----------------+| Variable_name | Value |+----------------------+-----------------+| collation_connection | utf8_general_ci || collation_database | utf8_general_ci || collation_server | utf8_general_ci |+----------------------+-----------------+3 rows in set (0.00 sec) mysql> |

四、yum安装MariaDB

[root@kevin ~]# yum -y install mariadb mariadb-server[root@kevin ~]# systemctl start mariadb[root@kevin ~]# systemctl enable mariadb 接下来进行MariaDB的相关简单配置，设置密码，会提示先输入密码[root@kevin ~]# mysql_secure_installation首先是设置密码，会提示先输入密码 Enter current password for root (enter for none):<–初次运行直接回车 设置密码 Set root password? [Y/n] <– 是否设置root用户密码，输入y并回车或直接回车New password: <– 设置root用户的密码Re-enter new password: <– 再输入一次你设置的密码 其他配置Remove anonymous users? [Y/n] <– 是否删除匿名用户，回车Disallow root login remotely? [Y/n] <–是否禁止root远程登录,回车,Remove test database and access to it? [Y/n] <– 是否删除test数据库，回车Reload privilege tables now? [Y/n] <– 是否重新加载权限表，回车 [root@kevin ~]# mysql -p123456Welcome to the MariaDB monitor.
