Phpcli configuration file problem analysis _ php instance

This article mainly introduces the analysis of phpcli configuration file problems. For more information, see Introduction

Today, when I was teaching others to use protobuf, I accidentally found a strange problem in the php cli mode. I spent a long time finding a solution. I 'd like to share it here.

Problem description

We first introduced the protobuf protocol, which was installed using the extension allegro/php-protobuf. This is also used by other colleagues in the past few days, so I put the part of the php class library file generated by protobuf to a public location/data/php_proto/folder, which contains this content,

Drwsrwxr-x 2 yanruitao users 4096 October 14 17:05 Dmp
-Rwxrwxr-x 1 yanruitao users 472 17:59 dmp. proto
Drwsrwxr-x 2 yanruitao users 4096 17:54 ProtobufCompiler
-Rwxrwxr-x 1 yanruitao users 2969 March 9 protoc-php.php

The following two are mandatory and will be used to generate pb protocol implementation class library files. The first two are a simple example, which is also very simple to use, as shown below.

Php protoc-php.php-n -- his dmp. proto //-n is using namespace, -- his is using psr-4 standards and other colleagues' use will report an error,

PHP Warning: file_put_contents (pb_proto_dmp.php): failed to open stream: Permission denied in/data/php_proto/ProtobufCompiler/ProtobufParser. php on line 309

When my colleague asked me, I directly said that we can add sudo, and The sudo problem is more serious. The originally installed extension cannot be loaded, after some troubleshooting, the following problem occurs:

$ Yanruitao: php-I | grep 'php. ini'
$ Yanruitao: sudo php-I | grep 'php. ini'

The two types of user load are not the same configuration file. Common users load/usr/local/php/lib/php. ini, while the root user loads/etc/php. ini file. I have read the inconsistency between the two files. Haha, I'm so happy. Hurry up and put/etc/php first. ini backup,/usr/local/php/lib/php. copy ini to/etc/php. ini. After I copied it, I was shocked when I used it again and reported a lot of errors:

Protoc-php.php (requires protobuf extension installed to run)

This leaves me confused.

After a long time, no breakthrough was found, but a standby solution was found to solve this problem. The permission to modify/data/php_proto/folder is 0775, other common users can use it directly without adding sudo (this is my fault. I forgot to modify the folder permission, which also caused me to find this strange problem)

Chmod-R 0775/data/php_proto
After reading these errors, most of them are expansion problems. Some of them cannot be loaded successfully, and some others do not exist. I am wondering why ordinary users can, but root users cannot.

When you see the root user php-I, the configuration file is different from the non-root User:

// Non-root

Scan this dir for additional. ini files => (none)
Additional. ini files parsed => (none)

// Root
Scan this dir for additional. ini files =>/etc/php. d
Additional. ini files parsed =>/etc/php. d/curl. ini,
......
Naming is loaded with the same configuration file. How can I load different content?
After searching for half a day, I learned that some of the errors I reported were related to this, but I still did not find any changes I found.

The php executable files used by root users and non-root users are inconsistent.

Root =>/usr/bin/php
Non-root =>/usr/local/bin/php

I tried to use php-v for these two files. As a result, I got a hop. the root user version is 5.3.3 and the non-root user is 5.4.6, WHO deployed the environment ~, Ah.

After trying to back up the original/usr/bin/php file, copy/usr/local/bin/php to overwrite it. When using php-v, we found that the version was consistent, also do not report the error, again to execute php protoc-php.php-n -- psr dmp. proto, found all is well, this problem is resolved.

After a long struggle, the result is the version issue.
