缘

过了个周末，舒舒服服，把家里捣鼓了下，自己编了一个网格照片墙，把来做客的家具都安排好位置，今天，继续上班啦。

环境

开始之前，老生常谈，首先看看我服务器的信息：

[root@VM-16-11-centos ~]# uname -aLinux VM-16-11-centos 3.10.0-1160.99.1.el7.x86_64 #1 SMP Wed Sep 13 14:19:20 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

下载

虽然每次写MySQL教程都会写下载链接，这次依然附带上。提供两种方式下载，
** 下载地址：**直接下载mysql数据库tar格式，官网下载地址
** 下载页面：**在页面找自己想要的版本进行安装，官网下载页面

安装

1. 离线服务器下载后放到服务器上，联网服务器直接使用命令下载：

wget https://dev.mysql.com/get/mysql-8.0.36-1.el7.x86_64.rpm-bundle.tar

2. 对压缩包进行解压

[root@VM-16-11-centos mysqls]# tar -xvf mysql-8.0.36-1.el7.x86_64.rpm-bundle.tar mysql-community-client-8.0.36-1.el7.x86_64.rpmmysql-community-client-plugins-8.0.36-1.el7.x86_64.rpmmysql-community-common-8.0.36-1.el7.x86_64.rpmmysql-community-debuginfo-8.0.36-1.el7.x86_64.rpmmysql-community-devel-8.0.36-1.el7.x86_64.rpmmysql-community-embedded-compat-8.0.36-1.el7.x86_64.rpmmysql-community-icu-data-files-8.0.36-1.el7.x86_64.rpmmysql-community-libs-8.0.36-1.el7.x86_64.rpmmysql-community-libs-compat-8.0.36-1.el7.x86_64.rpmmysql-community-server-8.0.36-1.el7.x86_64.rpmmysql-community-server-debug-8.0.36-1.el7.x86_64.rpmmysql-community-test-8.0.36-1.el7.x86_64.rpm[root@VM-16-11-centos mysqls]# lltotal 2012556-rw-r--r-- 1 root root1030420480 Dec 14 14:56 mysql-8.0.36-1.el7.x86_64.rpm-bundle.tar-rw-r--r-- 1 7155 31415 16767208 Dec 14 14:42 mysql-community-client-8.0.36-1.el7.x86_64.rpm-rw-r--r-- 1 7155 314153621168 Dec 14 14:42 mysql-community-client-plugins-8.0.36-1.el7.x86_64.rpm-rw-r--r-- 1 7155 31415 681264 Dec 14 14:42 mysql-community-common-8.0.36-1.el7.x86_64.rpm-rw-r--r-- 1 7155 31415528659552 Dec 14 14:43 mysql-community-debuginfo-8.0.36-1.el7.x86_64.rpm-rw-r--r-- 1 7155 314151948160 Dec 14 14:44 mysql-community-devel-8.0.36-1.el7.x86_64.rpm-rw-r--r-- 1 7155 314154217212 Dec 14 14:44 mysql-community-embedded-compat-8.0.36-1.el7.x86_64.rpm-rw-r--r-- 1 7155 314152344468 Dec 14 14:44 mysql-community-icu-data-files-8.0.36-1.el7.x86_64.rpm-rw-r--r-- 1 7155 314151563732 Dec 14 14:44 mysql-community-libs-8.0.36-1.el7.x86_64.rpm-rw-r--r-- 1 7155 31415 685408 Dec 14 14:44 mysql-community-libs-compat-8.0.36-1.el7.x86_64.rpm-rw-r--r-- 1 7155 31415 67429872 Dec 14 14:44 mysql-community-server-8.0.36-1.el7.x86_64.rpm-rw-r--r-- 1 7155 31415 25664528 Dec 14 14:45 mysql-community-server-debug-8.0.36-1.el7.x86_64.rpm-rw-r--r-- 1 7155 31415376818184 Dec 14 14:47 mysql-community-test-8.0.36-1.el7.x86_64.rpm

截图如下：

3. 安装解压出来的rpm安装包。如下：

[root@VM-16-11-centos mysqls]# rpm-ivh*.rpm --nodeps --forcewarning: mysql-community-client-8.0.36-1.el7.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID a8d3785c: NOKEYPreparing...################################# [100%]Updating / installing... 1:mysql-community-common-8.0.36-1.e################################# [8%] 2:mysql-community-client-plugins-8.################################# [ 17%] 3:mysql-community-libs-8.0.36-1.el7################################# [ 25%] 4:mysql-community-client-8.0.36-1.e################################# [ 33%] 5:mysql-community-icu-data-files-8.################################# [ 42%] 6:mysql-community-server-8.0.36-1.e################################# [ 50%] 7:mysql-community-server-debug-8.0.################################# [ 58%] 8:mysql-community-test-8.0.36-1.el7################################# [ 67%] 9:mysql-community-devel-8.0.36-1.el################################# [ 75%]10:mysql-community-libs-compat-8.0.3################################# [ 83%]11:mysql-community-embedded-compat-8################################# [ 92%]12:mysql-community-debuginfo-8.0.36-################################# [100%][root@VM-16-11-centos mysqls]# 

截图如下：
4. 使用命令查看安装是否成功，如下：

[root@VM-16-11-centos mysqls]# systemctl status mysqld● mysqld.service - MySQL Server Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled) Active: inactive (dead) Docs: man:mysqld(8) http://dev.mysql.com/doc/refman/en/using-systemd.html[root@VM-16-11-centos mysqls]# 

截图如下：

5. 启动mysql服务，如下：

[root@VM-16-11-centos mysqls]# systemctl status mysqld ● mysqld.service - MySQL Server Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled) Active: active (running) since Mon 2024-03-04 16:59:31 CST; 6s ago Docs: man:mysqld(8) http://dev.mysql.com/doc/refman/en/using-systemd.htmlProcess: 21984 ExecStartPre=/usr/bin/mysqld_pre_systemd (code=exited, status=0/SUCCESS) Main PID: 22106 (mysqld) Status: "Server is operational"Tasks: 38 Memory: 513.4M CGroup: /system.slice/mysqld.service └─22106 /usr/sbin/mysqldMar 04 16:59:18 VM-16-11-centos systemd[1]: Starting MySQL Server...Mar 04 16:59:31 VM-16-11-centos systemd[1]: Started MySQL Server.[root@VM-16-11-centos mysqls]# 

截图如下：

6. 查看数据库密码，和往常一样依然是随机密码，有日志可知本次密码为k*;2bsNU)&Oo，如下：

2024-03-04T08:59:22.920568Z 0 [System] [MY-013169] [Server] /usr/sbin/mysqld (mysqld 8.0.36) initializing of server in progress as process 220312024-03-04T08:59:22.949805Z 1 [System] [MY-013576] [InnoDB] InnoDB initialization has started.2024-03-04T08:59:23.861796Z 1 [System] [MY-013577] [InnoDB] InnoDB initialization has ended.2024-03-04T08:59:26.000382Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: k*;2bsNU)&Oo2024-03-04T08:59:31.115096Z 0 [System] [MY-010116] [Server] /usr/sbin/mysqld (mysqld 8.0.36) starting as process 221062024-03-04T08:59:31.131318Z 1 [System] [MY-013576] [InnoDB] InnoDB initialization has started.2024-03-04T08:59:31.335613Z 1 [System] [MY-013577] [InnoDB] InnoDB initialization has ended.2024-03-04T08:59:31.639123Z 0 [Warning] [MY-010068] [Server] CA certificate ca.pem is self signed.2024-03-04T08:59:31.639170Z 0 [System] [MY-013602] [Server] Channel mysql_main configured to support TLS.

截图如下：

7.测试数据库链接，命令如下：

[root@VM-16-11-centos ~]# mysql -u root -p Enter password: Welcome to the MySQL monitor.Commands end with ; or \g.Your MySQL connection id is 8Server version: 8.0.36Copyright (c) 2000, 2024, Oracle and/or its affiliates.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.mysql> 

截图如下：

8. 基于以上，mysql安装完成！烨！✌

可以连接以后，记得修改密码，命令：

ALTER USER USER() IDENTIFIED BY 'Root@123';

截图如下：

如果有修改配置文件的需求，使用以下命令修改配置文件，修改后重启生效：

[root@VM-16-11-centos ~]# vim /etc/my.cnf

截图如下：

问题集锦

1. 修改密码时报错：ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
   解决方案：
   意思是密码强度不够，试试大小写数字加符号。
   或者执行以下命令后重试：

#查看密码配置show variables like 'validate_password%';#设置密码强度SET GLOBAL validate_password.policy=LOW;SET GLOBAL validate_password.length=0;SET GLOBAL validate_password.mixed_case_count=0;SET GLOBAL validate_password.number_count=0;SET GLOBAL validate_password.special_char_count=0;FLUSH PRIVILEGES;ALTER USER USER() IDENTIFIED BY 'iceter';

修改成功，注意：不要修改成关键字，比如：root，依然会报错。

2. 安装时候报错：error: unpacking of archive failed: cpio: Bad magic
   解决方案：
   查看mysql版本与Linux系统版本是否一致。重新下载版本一致的进行安装即可。
