linux下安装mysql5.7.11全纪录_记一次linux下安装mysql5.7

一、首先是下载 适应的版本。

地址， https://dev.mysql.com/downloads/mysql/ ， 选择版本 mysql-5.7.28-1.el6.x86_64.rpm-bundle.tar 。 我下载的是 bundle ，各个文件全包括在内了。

检查linux是否已经有自带的mysql，如果有，删除掉。

rpm -qa |grep mysql

rpm-qa | grep mysql | xargs rpm -e --nodeps

解压bundle.tar 文件， 执行 rpm -ivh 命令安装 。如果过程中，碰到缺库问题，根据名字手动安装即可。

如果是redhat7/centos7，就用 mysql-5.7.29-1.el7.x86_64.rpm-bundle.tar。在安装过程中，会报出lib冲突。解决办法是，删除mariadb-libs。

[root@master mysql-5.7]# rpm -ivh mysql-community-client-5.7.29-1.el7.x86_64.rpm mysql-community-common-5.7.29-1.el7.x86_64.rpm mysql-community-devel-5.7.29-1.el7.x86_64.rpm mysql-community-libs-5.7.29-1.el7.x86_64.rpm mysql-community-libs-compat-5.7.29-1.el7.x86_64.rpm mysql-community-server-5.7.29-1.el7.x86_64.rpm

二、启动

service mysqld start

如果是centos7，使用 systemctl 命令。

[root@master mysql-5.7]# systemctl start mysqld

使用 mysql -u root -p 登录，提示要密码。在 /var/log/mysql.log 找到初始的密码。

cat /var/log/mysqld.log | grep password

再次登录即可。

三、首次修改密码

按照提示 必须要用 ALTER USER 的语法。

mysql> ALTER USER USER() IDENTIFIED BY 'Root1234@Root';

Query OK,0 rows affected (0.00 sec)

查看密码的设置要求。

mysql> SHOW VARIABLES LIKE 'vali%';+--------------------------------------+--------+

| Variable_name | Value |

+--------------------------------------+--------+

| validate_password_check_user_name | OFF |

| validate_password_dictionary_file | |

| validate_password_length | 8 |

| validate_password_mixed_case_count | 1 |

| validate_password_number_count | 1 |

| validate_password_policy | MEDIUM |

| validate_password_special_char_count | 1 |

+--------------------------------------+--------+

7 rows in set (0.01 sec)

自定义以上要求，降低密码的复杂度。

mysql> set global validate_password_policy=0;

Query OK,0 rows affected (0.00sec)

mysql> set global validate_password_special_char_count = 0

->;

Query OK,0 rows affected (0.00sec)

mysql> set global validate_password_length=4

->;

Query OK,0 rows affected (0.01 sec)

mysql> flush privileges;

Query OK, 0 rows affected (0.01 sec)

mysql> usemysql;

到这里， 修改密码完成。最后要重启mysql服务，才生效。

[root@master mysql-5.7]# systemctl status mysqld
