使用命令find / -name libmysqlclient.so*查詢libmysqlclient.so，發現確實缺少libmysqlclient.so.18
1、到mysql官網(https://downloads.mysql.com/archives/community/)下載安裝包
[root@localhost ~]# wget https://downloads.mysql.com/archives/get/file/mysql-community-libs-compat-5.7.22-1.el7.x86_64.rpm
2、安裝mysql-community-libs-compat-5.7.22-1.el7.x86_64.rpm。
[root@localhost ~]# rpm -ivh mysql-community-libs-compat-5.7.22-1.el7.x86_64.rpm
