Because the WordPress website used has modified the backend The address seems to be relatively safe, so I haven’t paid much attention to the logs of illegal logins to the website.
Today, the monitoring cloud alarm reported that the memory was low. After investigation, it was found that the website was scanned/brute force cracked. The log showed that the illegal login status had refreshed hundreds of pages.
Disable WordPress’s xmlrpc.php file to avoid brute force cracking
Analysis
Since there is a login failure record, first try to use the IP to enter the system log for matching. Select an IP that has been recorded for matching and execute the grep command:
grep "68.66.216.53" access.log
Seeing the log confirmed that the other party used POST to access the file/xmlrpc.php
Further use the command to track the number of occurrences of the xmlrpc.php file, and execute the grep and wc commands
grep "xmlrpc.php" access.log | wc -l
It shows that as of tonight, it has been detected in batches 57090 times
The key to solving
is to block/disable xmlrpc.php. In order to prevent possible side effects, I first searched Baidu and collected some information:
If the website program uses the pingback function, blocking xmlrpc.php will cause the function to be unusable
Use a plug-in such as JetPack, and then delete xmlrpc. php will cause website exception
Some components of the old version of WordPress depend on xmlrpc.php, and deleting it will cause some very strange problems
Currently, this site has nothing to do with the above three, so I can permanently solve this problem.
Use the rm -rf xmlrpc.php command to delete the xmlrpc.php file, but it is not recommended to delete it directly, because if something goes wrong, it will be troublesome without a backup.
Use the mv command to move this xmlrpc .php file (rename it as you like):
mv xmlrpc.php xmlrpc.php.sajdAo9ahnf$d9ha90hw9whw
Use the chmod command to disable all permissions of xmlrpc.php:
chmod 000 xmlrpc.php
The Apache server can set parameter jumps Transfer access:
<IfModule mod_alias.c> Redirect 301 /xmlrpc.php http://baidu.com </IfModule>
Nginx server can set parameters to prohibit access:
location ~* /xmlrpc.php { deny all; }

When managing WordPress projects with Git, you should only include themes, custom plugins, and configuration files in version control; set up .gitignore files to ignore upload directories, caches, and sensitive configurations; use webhooks or CI tools to achieve automatic deployment and pay attention to database processing; use two-branch policies (main/develop) for collaborative development. Doing so can avoid conflicts, ensure security, and improve collaboration and deployment efficiency.

Use WordPress testing environments to ensure the security and compatibility of new features, plug-ins or themes before they are officially launched, and avoid affecting real websites. The steps to build a test environment include: downloading and installing local server software (such as LocalWP, XAMPP), creating a site, setting up a database and administrator account, installing themes and plug-ins for testing; the method of copying a formal website to a test environment is to export the site through the plug-in, import the test environment and replace the domain name; when using it, you should pay attention to not using real user data, regularly cleaning useless data, backing up the test status, resetting the environment in time, and unifying the team configuration to reduce differences.

The key to creating a Gutenberg block is to understand its basic structure and correctly connect front and back end resources. 1. Prepare the development environment: install local WordPress, Node.js and @wordpress/scripts; 2. Use PHP to register blocks and define the editing and display logic of blocks with JavaScript; 3. Build JS files through npm to make changes take effect; 4. Check whether the path and icons are correct when encountering problems or use real-time listening to build to avoid repeated manual compilation. Following these steps, a simple Gutenberg block can be implemented step by step.

In WordPress, when adding a custom article type or modifying the fixed link structure, you need to manually refresh the rewrite rules. At this time, you can call the flush_rewrite_rules() function through the code to implement it. 1. This function can be added to the theme or plug-in activation hook to automatically refresh; 2. Execute only once when necessary, such as adding CPT, taxonomy or modifying the link structure; 3. Avoid frequent calls to avoid affecting performance; 4. In a multi-site environment, refresh each site separately as appropriate; 5. Some hosting environments may restrict the storage of rules. In addition, clicking Save to access the "Settings>Pinned Links" page can also trigger refresh, suitable for non-automated scenarios.
