使用rpm安装MySQL的方法:首先下载rpm包,当然小编为大家准备好了rpm包,大家可以直接去下载,也可以自行去寻找合适的rpm包进行安装。
MySQL5.7.21 rpm包下载路径
无论是哪种方式下载的rpm包,接下来都需要上传到需要安装MySQL的服务器上,小编使用的是FileZilla工具进行上传文件到服务器。
等待文件上传完成之后,我们就需要进入到对应的上传目录下,进行安装。小编使用的是最粗暴的安装方式进行安装:
[root@admin01 2]# rpm -ivh *.rpm --nodeps --force warning: mysql-community-client-5.7.21-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY Preparing... ################################# [100%] Updating / installing... 1:mysql-community-common-5.7.21-1.e################################# [ 8%] 2:mysql-community-libs-5.7.21-1.el7################################# [ 17%] 3:mysql-community-client-5.7.21-1.e################################# [ 25%] 4:mysql-community-server-5.7.21-1.e################################# [ 33%] 5:mysql-community-devel-5.7.21-1.el################################# [ 42%] 6:mysql-community-embedded-5.7.21-1################################# [ 50%] 7:mysql-community-embedded-devel-5.################################# [ 58%] 8:mysql-community-test-5.7.21-1.el7################################# [ 67%] 9:mysql-community-libs-compat-5.7.2################################# [ 75%] 10:mysql-community-embedded-compat-5################################# [ 83%] 11:mysql-community-server-minimal-5.################################# [ 92%] 12:mysql-community-minimal-debuginfo################################# [100%]
可以看见上面的MySQL已经成功安装,MySQL的安装并不需要这么多的rpm包,大家也可以根据自已的需要选择需要的rpm包进行安装。

默认MySQL的配置文件在/etc/my.cnf,找到该文件根据项目需要进行配置。修改完成后记得重启MySQL。
