Download and proxy configuration methods of Apache in the front end

Today, I joined a new company and came into contact with a different front-end development model than before. The first step is to configure Apache and proxy settings. For windows environment.

1. Download Apache.

1. Enter the official website.

//m.sbmmt.com/xiazai/gongju/fuwuqi You can see various versions of Apache. What I downloaded this time is Apache2.4.

2, enter the file download page.

A number of third party vendors. Jump to the download page for windows and select ApacheHaus.

3, download.

x86 is 64 bits. x64 is 32 bit. Just choose the download and decompression version that suits you.

4, basic configuration.

Go to the bin of the decompressed folder and open the command line. Enter httpd -k install to execute. If an error is reported. Enter the conf folder and open the httpd.conf file. Search Define SRVROOT. Change SRVROOT to the absolute path of Apache's root directory, taking my computer as an example. Define SRVROOT "D:\apache\httpd-2.4.27-x64-vc14\Apache24" ServerRoot "${SRVROOT}".

5, run.

Open the .exe program in the bin folder and enter localhost:8080 on the browser.

Note: If an error occurs, open the err.log in the logs folder to check the reason, Baidu it yourself, or leave a message to ask me.

2. Configuration of proxy server.

The interface of this project does not allow cross-domain, so the proxy can only be set when starting the local server. For example, the data required in the project is accessed from the 192.168.0.1:2030 domain name. The address of the local server is 127.0.0.1:8080. Then we need to request that the domain name be replaced with a local IP address on all interfaces of the project. Then when accessing the domain name /d/ folder. Converted to 192.168.0.1:2030/d/.

1. Open the httpd.conf file. Search for the mod_proxy keyword. The easiest way is to uncomment all proxies and add ProxyPass /d/ http://192.168.0.1:2030/d/ global definition at the end of the file. Then run the .exe. But in many cases it will fail because you don't have other modules required to open the agent. You can check it in the error.log file.

For example, I saw this time [Tue Sep 26 14:11:45.109636 2017] [proxy_hcheck:crit] [pid 2560:tid 324] AH03262: mod_watchdog is required. Then I will search for mod_watchdog in the httpd.conf file. Then uncomment and restart again.

Three, summary.

The server does not allow cross-domain and we, as the presentation layer, are powerless. As for setting up the proxy at the same time and changing the request source, you can get the data. This is a technology that a front-end developer must master.
