Generate SSH Public keyMost Git servers will choose to use the SSH public key for authorization. Each user in the system must provide a public key for authorization, and none will generate one. The process of generating the public key is similar on all operating systems. Fir
operation will fail.
Next, is to nobody users also create Ssh-key, the problem comes.
View PHP Process users
First, look at what users are running the PHP process in two ways:
The first way: View php-fpm.conf Configuration
First use the Find command to locate and view the file location:
[Root@localhost home]# Find/-name php-fpm.conf/usr/local/php-5.6.23/et

To copy a public key file to a remote server:
$ SCP ~/.ssh/id_dsa.pub User@remote.host:pubkey.txt$ ssh User@remote.host$ mkdir ~/.ssh$ chmod. SSH$ cat Pubkey.txt >> ~/.ssh/authorized_keys$ RM ~
Using Ssky-keygen and Ssh-copy-id in the example below, you can log in to a remote Linux host with a simple setup of 3 steps without entering a password.Ssh-keygen create public keys and keys.The Ssh-copy-id copies the local host's public key to the remote host's Authorized_keys file.Ssh-copy-id also sets the appropria

For example, if you want to log on to the 192.168.41.76 server as a root user without entering the user password.
1) create a public key and a private key on 192.168.41.76

For example, to the 192.168.41.76 server, do not enter a user password that is the root user login 192.168.41.75 server.

The second level is key-based security verification.
You need to rely on the key, that is, you must create a pair of keys for yourself, and put the public key on the server to be accessed. If you want to connect to the

Configuring the SSH key key locallyAfter the configuration, we need it here.
To start configuring SSH key locally, first check to see if the local computer has been configured for SSH

As PHP becomes more and more popular, Linux VPS/servers are used more and more, and Linux security issues need to be strengthened. If you have installed DenyHosts and set up email reminders, you may receive several DenyHosts reports every day to add the IP address that is used to crack the SSH password to/etc/hosts. deny.
There are two types of Linux SSH Logon:
1. Log On with password verification
