The main reason is that there was a vulnerability in openssl last month, so the server needs to be upgraded. It is recommended not to upgrade if there is no problem. The main steps are 2, and the script content also contains only the upgrade. 1 and 3 are to enable and disable telnet, it is not recommended to use telnet.
1 Install and start telnet
In fact, I did not use telnet, and there is a certain risk in opening it.
It is recommended to create an instance test of the server snapshot first, and you can open a few more ssh remote connections, so the general problem is not big.
1.1 Install xinetd/telnet-server/vsftpd
yum -y install xinetd yum -y install telnet-server yum -y install vsftpd
1.2 Modify the configuration file vim /etc/xinetd.d/telnet and change disable = yes to disable = no
flags = REUSE socket_type = stream wait = no user = root server = /usr/sbin/in.telnetd log_on_failure += USERID #disable = yes disable = no
1.3 Start and set up auto-start
service xinetd restart service vsftpd restart systemctl start telnet.socket && systemctl enable telnet.socket
1.4 If there is a firewall, you need to release port 23 (Aliyun release)
firewall-cmd --zone=public --add-port=23/tcp --permanent
1.5 When using telnet to connect to the server, root login is not allowed by default. You need to create a user and grant sudo permission (if you already have a user and have sudo permission, you can skip it)
# Add a user and set a password (centos7 is the user name, password ruijie123, > can be modified) useradd centos7 echo ruijie123 | passwd --stdin centos7 # Increase the sudo permission of the centos7 account # Add the configuration in the configuration file /etc/sudoers, but the file does not have write permission by default, so you need to increase the write permission first chmod u+w /etc/sudoers vi /etc/sudoers centos7 ALL=(ALL) ALL
1.6 Use the telnet command in the terminal under windows to test the connection (port 23 by default)
telnet ip address 23
2 Execute openssh and openssl compilation update
Be sure to open a few more ssh remote connections! ! ! ! ! ! Prevent accidental disconnection in the middle! ! ! ! ! !
2.1 Put the script file and the three downloaded compressed packages in the opt directory (just the same directory), execute the script, and complete the installation
Make the script file, the script file is in 4, just download the other three compressed packages by yourself, or don’t download it, the script will be downloaded automatically.
sh upopenssh.sh
If the upgrade fails, back up the configuration, directly use yum to reinstall the built-in ssh, and confirm the configuration.
Confirm that it is automatically started at boot
chkconfig --list sshd # sshd 0: off 1: off 2: on 3: on 4: on 5: on 6: off
3 Close telnet, delete it after the openssh test is normal (if using telnet, be sure to close it)
3.1 Close telnet and firewall port 23
service xinetd stop && service vsftpd stop systemctl stop telnet.socket && systemctl disable telnet.socket firewall-cmd --remove-port=23/tcp --permanent ##### 3.2 Uninstall telnet rpm -e telnet-server
3.3 If there is no configured user before, it is not required (not necessary)
# delete users userdel -r centos7 # Edit the sudo configuration file and remove the corresponding configuration section vi /etc/sudoers # Restore the permissions of the sudo configuration file chmod u-w /etc/sudoers
4 upopenssh.sh script
Note that openssl 3.0 cannot be used here, the dependencies required by 3.0 are different, and an error will be reported; all 1.x versions should be available.
There is a backup process, and the upgrade and compilation process will be restored if it fails. However, the restoration effect has only been tested manually without actual verification. I have succeeded.
The ssh configuration is reserved, and you need to modify it yourself in some places.
script source Detailed upgrade steps of the latest version of Linux OpenSSH-9.0p1 (with script)
I made my own modifications, mainly to retain the configuration and add some handling of failed operations.
