CentOS8编译安装MySQL8发生Could not find rpcgen错误

CMake Error at plugin/group_replication/libmysqlgcs/cmake/rpcgen.cmake:104 (MESSAGE):
  Could not find rpcgen
Call Stack (most recent call first):
  plugin/group_replication/libmysqlgcs/CMakeLists.txt:53 (INCLUDE)

在CentOS8下编译安装MySQL8可能会出现Could not find rpcgen错误，而CentOS8默认的yum源下不提供rpcgen的安装包。所以需要到rpcgen的GitHub仓库上找，地址如下：

https://github.com/thkukuk/rpcsvc-proto/releases

解决办法：

[root@lnmp mysql-8.0.21]# cd /opt/
[root@lnmp opt]#  wget https://github.com/thkukuk/rpcsvc-proto/releases/download/v1.4/rpcsvc-proto-1.4.tar.gz
[root@lnmp opt]# tar xf rpcsvc-proto-1.4.tar.gz 
[root@lnmp opt]# cd rpcsvc-proto-1.4/
[root@lnmp rpcsvc-proto-1.4]# ./configure && make && make install
