The http_port directive in squid.conf sets the port number or numbers that Squid will use to listen for client requests. You can specify multiple socket addresses with different port numbers and options. By default, Squid listens on port 3128 on all network interfaces. You can change the port number or bind the socket to a specific IP address if needed. For example, to set the port to 8080, you can write:

http_port 8080

To configure Squid to listen only on the 192.0.2.1 IP address on port 3128, you can write:

http_port 192.0.2.1:3128

 The options rw and ro are valid in /etc/exports. They specify whether the exported file system is mounted with read-write or read-only permissions by the clients. The option rw allows the clients to modify the files on the server, while the option ro prevents any changes by the clients. These options can be applied to all or specific hosts in the /etc/exports file123 References:

 The ErrorLog directive of the Apache HTTPD server defines the location and name of the file where the server will log any errors it encounters. The default value of this directive is logs/error_log, which means that the error log file will be stored in the logs subdirectory of the server root directory. The ErrorLog directive can also accept a filename relative to the server root, an absolute filename, or a pipe to a program that will handle the logging. For example, ErrorLog logs/my_error_log will store the error log file in the logs subdirectory with the name my_error_log, ErrorLog /var/log/httpd/error_log will store the error log file in the /var/log/httpd directory with the name error_log, and ErrorLog “|bin/rotatelogs logs/error_log 86400” will pipe the error log to the rotatelogs program that will rotate the log file every 86400 seconds. References: Log Files - Apache HTTP Server Version 2.4, Directive Quick Reference - Apache HTTP Server Version 2.4, How do I find Apache http server log files? – Code A Site Blog, mod_log_config - Apache HTTP Server Version 2.2
