# It is esp. important, to have correct metadata, for distributions like

安装telnet服务并启用
因升级OpenSSH过程中需要卸载现有OpenSSH, 因此为了保持服务器的远程连接可用，需
要启用telnet服务作为替代，如升级出现问题，也可通过telnet登录服务器进行回退。
同时安装telnet守护进程：xinetd
安装telnet服务

重启服务：
由于telnet服务也是由xinetd守护的，所以安装完telnet-server，要启动telnet服务就必须重新启动xinetd
[root@localhost ~]#
[root@localhost ~]# systemctl restart telnet.socket
[root@localhost ~]#
[root@localhost ~]# systemctl restart xinetd
[root@localhost ~]#
[root@localhost ~]#
配置telnet root用户访问
linux默认情况下root用户使用telnet是登录不了的，需要修改/etc/secrueety文件末尾加入pts/1、pts/2、pts/3或者可以把secrueety文件重命名均可；

卸载当前zlib
注意：此步骤必须在步骤A执行完毕后再执行，否则先卸载zlib后，/lib64/目录下的zlib相
关库文件会被删除，步骤A编译zlib会失败。（补救措施：从其他相同系统的服务器上复
制/lib64、/usr/lib和/usr/lib64目录下的libcrypto.so.10、libssl.so.10、libz.so.1、libz.so.1.2.3
四个文件到相应目录即可。可通过whereis、locate或find命令找到这些文件的位置）
