1.Mariadb 5.5.44远程登录MySQL8.0.22出现认证机制出错
mysql -uroot -h mysql-server-ip -p Enter password: ERROR 2059 (HY000): Authentication plugin 'caching_sha2_password' cannot be loaded: /usr/lib64/mysql/plugin/caching_sha2_password.so: cannot open shared object file: No such file or directory ##解决方案,修改root账号的认证方式 alter user 'root'@'%' identified with mysql_native_password by 'password'; flush privileges;
2.xrdp在使用中出现超过再大连接数的问题,在日志文件中出现错误【X server -- no display in range is available】
vim /etc/xardp/sesman.ini ##修改MaxSessions的默认值 MaxSessions=20
