Centos8 安裝 mysql5.7 過程中所遇到的問題 libsasl2.so.2

首先，下載MySQL的yum源的rpm包

wget https://dev.mysql.com/get/mysql57-community-release-el6-9.noarch.rpm

然後，安裝mysql的yum源的rpm包

rpm -Uvh mysql57-community-release-el6-9.noarch.rpm

搞定後，執行

yum install mysql-community-server

在這個時候，會出現一個錯誤

Error:
 Problem: cannot install the best candidate for the job
  - nothing provides libsasl2.so.2()(64bit) needed by mysql-community-server-5.7.30-1.el6.x86_64
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

對應方案則是
找到 /etc/yum.repos.d/mysql-community.repo
打開後，找到 [mysql57-community] 這一塊配置(將加粗的兩個位置更新一下)
baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/7/$basearch/
gpgcheck=0

即可。
