Configure autofs.
Configure the autofs automatically mount to the home directory of LDAP, as required: server.domain11.example.com use NFS to share the home to your system. This file system contains a pre configured home directory of user ldapuserX.
Home directory of ldapuserX is: server.domain11.example.com /home/guests/ldapuser
Home directory of ldapuserX should automatically mount to the ldapuserX of the local /home/guests Home directory’s write permissions must be available for users ldapuser1’s password is password
Solution:
yum install -y autofs
mkdir /home/rehome
/etc/auto.master
/home/rehome/etc/auto.ldap
Keep then exit
cp /etc/auto.misc /etc/auto.ldap /etc/auto.ldap
ldapuserX -fstype=nfs,rw server.domain11.example.com:/home/guests/
Keep then exit
systemctl start autofs
systemctl enable autofs
su - ldapuserX// test
If the above solutions cannot create files or the command prompt is -bash-4.2$, it maybe exist multi-level directory, this needs to change the server.domain11.example.com:/home/guests/ to server.domain11.example.com:/home/guests/ldapuserX. What is multi-level directory? It means there is a directory of ldapuserX under the /home/guests/ldapuserX in the questions. This directory is the real directory.

One Logical Volume is created named as myvol under vo volume group and is mounted. The Initial Size of that Logical Volume is 400MB. Make successfully that the size of Logical Volume 200MB without losing any data. The size of logical volume 200MB to 210MB will be acceptable.
Solution:
First check the size of Logical Volume: lvdisplay /dev/vo/myvol Make sure that the filesystem is in a consistent state before reducing:
# fsck -f /dev/vo/myvol Now reduce the filesystem by 200MB.
# resize2fs /dev/vo/myvol 200M It is now possible to reduce the logical volume. #lvreduce /dev/vo/myvol -L 200M Verify the Size of Logical Volume: lvdisplay /dev/vo/myvol Verify that the size comes in online or not: df -h

According the following requirements, configure autofs service and automatically mount to user's home directory in the ldap domain.
- Instructor.example.com (192.168.0.254) has shared /home/guests/ldapuserX home directory to your system by over NFS export, X is your hostname number.
- LdapuserX's home directory is exist in the instructor.example.com: /home/ guests/ldapuserX
- LdapuserX’s home directory must be able to automatically mount to /home/ guests/ldapuserX in your system.
- Home directory have write permissions for the corresponding user.
However, you can log on to the ldapuser1 - ldapuser99 users after verification. But you can only get your corresponding ldapuser users. If your system's hostname is server1.example.com, you can only get ldapuser1's home directory.
Solution:
(1)find /etc -size 10k -exec cp {} /tmp/findfiles ;
(2)find / -user lucy -exec cp -a {} /tmp/findfiles ;
Note: If find users and permissions, you need to use cp - a options, to keep file permissions and user attributes etc.

You have a domain named www.rhce.com associated IP address is 192.100.0.2. Configure the Apache web server by implementing the SSL for encryption communication.
Solution:
vi /etc/httpd/conf.d/ssl.conf
/var/www/rhce DirectoryIndex index.html index.htm ServerAdmin webmaster@rhce.com SSLEngine on SSLCertificateFile /etc/httpd/conf/ssl.crt/server.crt SSLCertificateKeyFile
/etc/httpd/conf/ssl.key/server.key cd /etc/httpd/conf 3 make testcert Create the directory and index page on specified path. (Index page can download from ftp://server1.example.com at exam time) service httpd start|restart chkconfig httpd on
Apache can provide encrypted communications using SSL (Secure Socket Layer). To make use of encrypted communication, a client must request to https protocol, which is uses port 443. For HTTPS protocol required the certificate file and key file.
