php cli配置文件问题

引言

今天在教别人使用protobuf的时候,无意中发现了一个php cli模式下的诡异问题,费了老半天的找到解决方法了,这里拿出来分享下。

问题描述

我们这边最先引入了protobuf协议,使用的是allegro/php-protobuf这个扩展安装的。这几天其他同事也要用到这个,于是我将protobuf生成php类库文件的部分放到了一个公共的位置/data/php_proto/文件夹下,里面有这些内容,

<code>drwsrwxr-x 2 yanruitao users 4096 10月 14 17:05 Dmp-rwxrwxr-x 1 yanruitao users  472 10月 10 17:59 dmp.protodrwsrwxr-x 2 yanruitao users 4096 10月 10 17:54 ProtobufCompiler-rwxrwxr-x 1 yanruitao users 2969 3月   9 2015 protoc-php.php</code>

后面两个是必须的,生成pb协议实现类库文件时会用到,前面两个是一个简单的例子,使用也很简单,就像下面这样。

<code>php protoc-php.php -n --psr dmp.proto //-n是使用命名空间,--psr是使用psr-4标准</code>

等同事用的时候发现会报错,

<code>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</code>

同事问我的时候我直接说,加上sudo就可以了,结果加上sudo问题更严重了,本来装好的扩展程序加载不成功,经过一番排查发下有下面这么一个问题:

<code>$yanruitao: php -i | grep 'php.ini'$yanruitao: sudo php -i | grep 'php.ini'</code>

两种用户加载的不是同一个配置文件,普通用户加载的是/usr/local/php/lib/php.ini,而root用户加载的是/etc/php.ini这个文件,我看了下这两个文件内容不一致,哈哈,好开心,赶紧把先把/etc/php.ini备份,/usr/local/php/lib/php.ini复制到/etc/php.ini,复制完了之后,我再使用的时候吓我一跳,报了一大堆错误:

这让我摸不着头脑了。

时间过去了好久,没有发现任何突破,却发现了一个备用的解决这个问题的方案,修改/data/php_proto/文件夹权限为0775,其他普通用户就可以直接使用了,不用加sudo(这个是我的错,忘记修改文件夹权限了,这也让我发现了这个诡异的问题)

<code>chmod -R 0775 /data/php_proto</code>

看了报的这些错误,大部分都是扩展的问题,有的是扩展加载不成功,有的是扩展不存在,我就纳闷了,为什么普通用户可以,root用户就不可以。

看到root用户php -i的时候,配置文件的地方跟非root用户有不一致的地方:

<code>//非rootScan this dir for additional .ini files => (none)Additional .ini files parsed => (none)//rootScan this dir for additional .ini files => /etc/php.dAdditional .ini files parsed => /etc/php.d/curl.ini,......</code>

命名加载的是一样的配置文件怎么加载之后的内容就不一样呢?
搜了半天,知道了报的错里面有部分是跟这个有关系的,但是这个在哪里修改搜了老久也没有搜到。

忽然想到root用户和非root用户使用的php可执行文件是不一致的

<code>root => /usr/bin/php非root => /usr/local/bin/php</code>

尝试着对这两个文件使用了php -v,结果下了我一跳,root用户的版本是5.3.3,非root用户是5.4.6,呵呵,我就呵呵了,谁部署的环境~,坑人啊。

尝试着将原有/usr/bin/php备份后,复制/usr/local/bin/php过来覆盖掉,在使用php -v发现版本一致了,也不报错了,再次去执行php protoc-php.php -n --psr dmp.proto,发现all is well,至此问题解决。

纠结了半天,结果就是版本的问题。

总结

多思考,多换个角度思考。
做事要完善啊,别给后辈留下一些诡异问题←_←。
