Sometimes, we can not connect to the external network directly, we may need to connect to the proxy server in order to access the external network, install the software package and upgrade the program. At this time, we need to configure some proxy settings to ensure that the network is normal.

I. Global server environment variables

Set the global proxy as follows:

Modify the / etc/profile file to add the following:

Http_proxy= http://username:password@yourproxy:8080/ftp_proxy=http://username:password@yourproxy:8080/export http_proxyexport ftp_proxy

If there is no password limit, the above can be modified to:

Http_proxy= http://yourproxy:8080/ftp_proxy=http://yourproxy:8080/export http_proxyexport ftp_proxy

If it is only for a user, modify the ~ / .bash_profile file to add the same content

After the modification is completed, log out and log back in.

II. Yum proxy settings

Open the yum configuration file with a vi editor, in general: vi / etc/yum.conf

After opening the configuration file of yum, add the protocol, address and port of the proxy server at the end of the file, and the user name and password of the authenticated user if the proxy server requires user authentication.

Proxy server does not require authentication: plus proxy= protocol: / / proxy server address: Port (e.g. proxy= http://192.168.1.1:80)

The proxy server needs to authenticate the user: plus proxy= protocol: / / proxy server address: Port (e.g. proxy= http://192.168.1.1:80)

Proxy_username= proxy server username proxy_password= proxy server password

After saving and exiting, you can easily install the software using yum.

3. Git proxy settings git config-- global https.proxy https://proxyuser:proxypassword@ip/ domain name: portgit config-- global http.proxy http://proxyuser:proxypassword@ip/ domain name: port

Example:

Suppose someone works for Baidu, the company proxy server is (proxy.baidu.com), the port is (8080), and the agent configuration is as follows

1. Authentication configuration is required for proxy server

Git config-- global https.proxy https://username:password@proxy.baidu.com:8080

2. The proxy server does not need authentication configuration.

Git config-- global https.proxy https://proxy.baidu.com:8080

4. Some special characters in the agent configuration

If there are special characters such as @ in the password, there will be an error, such as

Git config-- global http.proxy http://username:abc@123@proxy.baidu.com:8080

When parsing, it will parse from the first @, prompting @ 123@proxyhk.huawei.com to find it. At this time, you need to deal with the special symbols in it, and use percentage encoding (Percent-encoding) to convert and convert the special characters.

The list is as follows:

!-- >% 21 #-- >% 23 $- >% 24 &->% 26'- >% 27 (-->% 28)-- >% 29 *->% 2A +->% 2B,-- >% 2C/-- >% 2F:-- >% 3A -- >% 3B =-- >% 3D?-- >% 3F@-- >% 40 [-->% 5B]-- >% 5D

For example: agent account: admin

Agent password: abc@123br/ > Agent account: admin

Agent password: abc@123

Proxy server: http://172.31.101.102:8080

When performing a global proxy, you need to configure as follows

Http://admin:abc%40123@172.31.101.120:8080
