解决：如何在linux上安装mysql数据库

╰半夏微凉° 2024-04-18 10:34 11阅读 0赞

第一步：在mysql网站上找到你要安装的程序

mysql官网地址：[MySQL][]

我下载的是：[https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm][https_dev.mysql.com_get_mysql80-community-release-el7-3.noarch.rpm]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25nXzE2ODE2Mw_size_16_color_FFFFFF_t_70][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25nXzE2ODE2Mw_size_16_color_FFFFFF_t_70 1][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25nXzE2ODE2Mw_size_16_color_FFFFFF_t_70 2][]

我的linux是centos，所以我选择是下面这个选项

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25nXzE2ODE2Mw_size_16_color_FFFFFF_t_70 3][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25nXzE2ODE2Mw_size_16_color_FFFFFF_t_70 4][]

鼠标点击Download，右键 复制链接地址

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25nXzE2ODE2Mw_size_16_color_FFFFFF_t_70 5][]

第二步：使用linux下载mysql，如果安装过程中出现下面的无法建立ssl链接，请参考文档：[关于weget “无法建立SSL连接”的解决方法\_unable to find public key parameters 无法建立 ssl 连接。\_yohe233的博客-CSDN博客][weget _SSL_unable to find public key parameters _ ssl _yohe233_-CSDN]

或者：原命令加上"--no-check-certificate"选项，就能排除掉这个错误。

1.执行命令：\[root@localhost \]\# wget --no-check-certificate https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25nXzE2ODE2Mw_size_16_color_FFFFFF_t_70 6][]

下载的时候linux里面的网络一定要打开

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25nXzE2ODE2Mw_size_16_color_FFFFFF_t_70 7][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25nXzE2ODE2Mw_size_16_color_FFFFFF_t_70 8][]

2.安装完成执行命令：\[root@localhost \]\# rpm -ivh mysql80-community-release-el7-3.noarch.rpm

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25nXzE2ODE2Mw_size_16_color_FFFFFF_t_70 9][]

3.执行命令：\[root@localhost \]\# yum makecache

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25nXzE2ODE2Mw_size_16_color_FFFFFF_t_70 10][]

4.执行命令：\[root@localhost \]\# yum list | grep mysql-com

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25nXzE2ODE2Mw_size_16_color_FFFFFF_t_70 11][]

5.执行安装命令：\[root@localhost \]\# yum install mysql-community-server.x86\_64 ，输入y

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25nXzE2ODE2Mw_size_16_color_FFFFFF_t_70 12][]

![20190905153923313.png][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25nXzE2ODE2Mw_size_16_color_FFFFFF_t_70 13][]

6.查看一下刚刚安装的软件。

\[root@localhost lib\]\# systemctl start mysqld  
\[root@localhost lib\]\# ll

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25nXzE2ODE2Mw_size_16_color_FFFFFF_t_70 14][]

7.查看mysql的初始密码是多少，执行命令：\[root@localhost lib\]\# grep "password" /var/log/mysqld.log

![20190905154232587.png][]

8.登录mysql，执行命令：\[root@localhost lib\]\# mysql -uroot -p

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25nXzE2ODE2Mw_size_16_color_FFFFFF_t_70 15][]
