以下操作均在192.168.4.51上执行，既充当服务端，又充当客户端
搭建nis
服务端
1.装包，查看信息
yum -y install ypbind.x86_64 3:1.37.1-9.el7 ypserv.x86_64 0:2.31-10.el7
[root@mysql_server_51 ~]# rpm -qa| grep ypserv| xargs rpm -qc
/etc/sysconfig/yppasswdd
/etc/ypserv.conf
/var/yp/Makefile
[root@mysql_server_51 ~]# rpm -qa| grep ypbind| xargs rpm -qc
/etc/yp.conf
2.修改配置文件
[root@mysql_server_51 ~]# vim /etc/sysconfig/network
NISDOMAIN=hpc
[root@mysql_server_51 ~]# nisdomainname
nisdomainname: Local domain name not set
[root@mysql_server_51 ~]# systemctl restart ypserv
[root@mysql_server_51 ~]# systemctl restart yppasswdd.service
[root@mysql_server_51 ~]# nisdomainname
hpc
3.添加测试用户
[root@mysql_server_51 ~]# useradd test
[root@mysql_server_51 ~]# echo 123456 | passwd --stdin test
[root@mysql_server_51 ~]# useradd test1
[root@mysql_server_51 ~]# echo 123456 | passwd --stdin test1
4.同步数据库：
[root@mysql_server_51 ~]# cd /var/yp/
[root@mysql_server_51 yp]# ls
binding Makefile nicknames
[root@mysql_server_51 yp]# make
[root@mysql_server_51 yp]# ls
binding hpc Makefile nicknames
客户端
1。装包
yum -y install ypbind.x86_64 3:1.37.1-9.el7
2.修改配置文件
[root@mysql_server_51 yp]# vim /etc/yp.conf
domain hpc server 192.168.4.51
[root@mysql_server_51 yp]# vim /etc/nsswitch.conf
33 passwd: files nis sss
34 shadow: files nis sss
35 group: files nis sss
3.开启服务
[root@mysql_server_51 yp]# systemctl start ypbind.service
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
在192.168.4.52上做客户端
1。装包
yum -y install ypbind.x86_64 3:1.37.1-9.el7
2.从51上拷贝文件
[root@mysql_server_51 hpc]# scp /etc/sysconfig/network [email protected]:/etc/sysconfig/network
[root@mysql_server_51 hpc]# scp /etc/yp.conf /etc/nsswitch.conf [email protected]:/etc/
3.查看用户信息，可以查看到在192.168.4.51上创建的用户
[root@mysql_server_52 ~]# ypcat passwd
lisi:$6$2N.hQXlLD73P0Uwh$BDxynKumwbYqnLoY33myAlwstFyuWaJGLygv4E0OF/lLyLnHinWFzjDxZXdeH/kTG19iwzmaSYVPbSh9jWaLC.:1000:1000:lisi:/home/lisi:/bin/bash
test:$6$5pOnHybb$oTEERn2E/s0P7d5sei.Bsrmrudkc5.U0gg85p7hKqEawCCcV66TwJL4KPWzlsNuOlkexUs2.7UZX8kOZc7tW6/:1001:1001::/home/test:/bin/bash
test1:$6$x54C5ZQK$IeK.feBkwyEbpkwmrGR7qnehItsd1ycF/36LsneBP6UStRik7fYhVQcJBR0sLv3mxbYvxb1cPRfoZD2FdLm.K.:1002:1002::/home/test1:/bin/bash
4.在真机上使用test用户登录192.168.4.52
[root@room9pc01 ~]# ssh [email protected]
[email protected]'s password:
Could not chdir to home directory /home/test: No such file or directory
-bash-4.2$
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
后续实现autonfs自动挂载家目录
在192.168.4.52上共享/home 目录
在测试机上实现autofs
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
tmux的命令使用，一个窗口充当多个终端，防止网络断线
在真机上实验
1.装包
[root@room9pc01 ~]# yum -y install tmux
直接执行如下的命令，底部会出现绿色的提示
[root@room9pc01 ~]# tmux
ctrl+b d 退出会话连接
连接某个会话
[root@room9pc01 ~]# tmux attach -t 0
[detached]
[root@room9pc01 ~]# tmux ls
0: 1 windows (created Fri May 4 20:27:31 2018) [116x32]
杀死会话，（可以在tmux的终端执行，也可以在原始终端执行）
[root@room9pc01 ~]# tmux kill-session -t 0
创建会话，-s 指定回话的名称
[root@room9pc01 ~]# tmux new -s top
杀掉会话
[root@room9pc01 ~]# tmux kill-session -t top
列出会话
[root@room9pc01 ~]# tmux ls
t: 1 windows (created Fri May 4 20:34:37 2018) [116x32] (attached)
关闭会话
ctrl+b &
exit
开启一个新的窗口
