tomcat set ip proxy: Apache Tomcat server proxy IP configuration detailed graphic tutorials

First, Tomcat why need to hang proxy IP?

For example, just like online shopping to use different shipping addresses to prevent being pulled by merchants, the server sometimes have to change the "armor" to work stably. Especially when doing data collection, bulk registration of these operations, using their own real IP is easy to be blocked by the target site, this time you have to rely on the proxy IP towork incognitoThe

Tomcat as an old Java server , many enterprises use it to do business systems . But directly in the server code to write the proxy logic is too much trouble, not as good as directly configured at the server level, saving time and effort and security.

Second, the hands-on configuration tutorial

Let's do it in three steps: first prepare the proxy resources, then change the configuration file, and finally test and verify.

1. Get a reliable proxy IP

This is a must.ipipgoHome service, their static residential IP is especially suitable for enterprise level business. After opening the official website and registering, find the consoleAPI Extraction Portal, select the Socks5 protocol type (supported natively by Tomcat). Get the format like this:

123.45.67.89:1080:username:password

2. Modify the catalina.properties.

Locate the conf folder in the Tomcat installation directory and open it with Notepadcatalina.properties, add these parameters at the end of the file:

socksProxyHost=123.45.67.89
socksProxyPort=1080
java.net.socks.username=username
java.net.socks.password=password

Watch out for potholes:Don't use Chinese symbols, and don't put spaces on either side of the equal sign! Remember to save the file after the change.

3. Reboot and validate

Open cmd and execute the command:

netstat -ano | findstr 1080

Seeing the ESTABLISHED status indicates a successful connection. Revisithttps://ipipgo.com/checkipThe IP displayed should become a proxy IP.

III. Common rollover site QA

Q: What should I do if the IP does not take effect after I configure it?
A: First check the three pieces of kit: 1. Proxy service expires 2. Port protocols match 3. Tomcat restarted yet

Q: What about the snail-like agent speed?
A: Recommended to change ipipgo'sTK LineThe delay can be reduced to less than 50ms. Don't be greedy and use free proxies, you'll get screwed in a minute!

Q：What should I do if I need to use multiple proxy IPs at the same time?
A: In this case it is recommended to go on their homeAPI Dynamic ExtractionIf you want to change the configuration file, you can write an IP pool polling in the code, which is much more flexible than changing the configuration file.

IV. The doorway to selecting agency services

Agents on the market are a mixed bag, teaching you to see the set:

focus onIP purityrespond in singingProtocol SupportSome of the IPs of small workshops have long been blacklisted by major platforms, and using such is tantamount to spending money for nothing.

V. Say something heartfelt

Used seven or eight agent services, ipipgo the most worry-free three points: 1. customer service response fast 2. IP pool updated in a timely manner 3. do not play sets of billing. Especially friends doing cross-border e-commerce, their homecross-border rail lineIt saves a lot of work, so don't drop the ball on agents when it counts.

Lastly, remember to check IP availability periodically. If you have the conditions on the enterprise version of the package, with automatic switching, than the manual maintenance of much more worry.
