弁言PHP教程

今天在教別人使用protobuf的時(shí)候,無意中發(fā)現(xiàn)了一個(gè)php cli模式下的詭異問題,費(fèi)了老半天的找到解決辦法了,這里拿出來分享下.PHP教程

問題描述PHP教程

我們這邊最先引入了protobuf協(xié)議,使用的是allegro/php-protobuf這個(gè)擴(kuò)展安裝的.這幾天其他同事也要用到這個(gè),于是我將protobuf生成php類庫文件的部分放到了一個(gè)公共的位置/data/php_proto/文件夾下,里面有這些內(nèi)容,PHP教程

drwsrwxr-x 2 yanruitao users 4096 10月 14 17:05 Dmp
-rwxrwxr-x 1 yanruitao users? 472 10月 10 17:59 dmp.proto
drwsrwxr-x 2 yanruitao users 4096 10月 10 17:54 ProtobufCompiler
-rwxrwxr-x 1 yanruitao users 2969 3月?? 9 2015 protoc-php.php
PHP教程

后面兩個(gè)是必需的,生成pb協(xié)議實(shí)現(xiàn)類庫文件時(shí)會(huì)用到,前面兩個(gè)是一個(gè)簡單的例子,使用也很簡單,就像下面這樣.PHP教程

php protoc-php.php -n --psr dmp.proto //-n是使用命名空間,--psr是使用psr-4標(biāo)準(zhǔn)等同事用的時(shí)候發(fā)現(xiàn)會(huì)報(bào)錯(cuò),PHP教程

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
PHP教程

同事問我的時(shí)候我直接說,加上sudo就可以了,結(jié)果加上sudo問題更嚴(yán)重了,原來裝好的擴(kuò)展程序加載不成功,經(jīng)過一番排查發(fā)下有下面這么一個(gè)問題：PHP教程

$yanruitao: php -i | grep 'php.ini'
$yanruitao: sudo php -i | grep 'php.ini'
PHP教程

兩種用戶加載的不是同一個(gè)配置文件,普通用戶加載的是/usr/local/php/lib/php.ini,而root用戶加載的是/etc/php.ini這個(gè)文件,我看了下這兩個(gè)文件內(nèi)容不一致,哈哈,好開心,趕緊把先把/etc/php.ini備份,/usr/local/php/lib/php.ini復(fù)制到/etc/php.ini,復(fù)制完了之后,我再使用的時(shí)候嚇我一跳,報(bào)了一大堆錯(cuò)誤:PHP教程

這讓我摸不著頭腦了.PHP教程

時(shí)間過去了好久,沒有發(fā)現(xiàn)任何突破,卻發(fā)現(xiàn)了一個(gè)備用的辦理這個(gè)問題的方案,修改/data/php_proto/文件夾權(quán)限為0775,其他普通用戶就可以直接使用了,不用加sudo(這個(gè)是我的錯(cuò),忘記修改文件夾權(quán)限了,這也讓我發(fā)現(xiàn)了這個(gè)詭異的問題)PHP教程

chmod -R 0775 /data/php_proto
看了報(bào)的這些錯(cuò)誤,大部分都是擴(kuò)展的問題,有的是擴(kuò)展加載不成功,有的是擴(kuò)展不存在,我就納悶了,為什么普通用戶可以,root用戶就不可以.PHP教程

看到root用戶php -i的時(shí)候,配置文件的地方跟非root用戶有不一致的地方：PHP教程

//非root
PHP教程

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

//root
Scan this dir for additional .ini files => /etc/php.d
Additional .ini files parsed => /etc/php.d/curl.ini,
......
命名加載的是一樣的配置文件怎么加載之后的內(nèi)容就不一樣呢?
搜了半天,知道了報(bào)的錯(cuò)里面有部分是跟這個(gè)有關(guān)系的,但是這個(gè)在哪里修改搜了老久也沒有搜到.PHP教程

忽然想到root用戶和非root用戶使用的php可執(zhí)行文件是不一致的PHP教程

root => /usr/bin/php
非root => /usr/local/bin/php
PHP教程

嘗試著對(duì)這兩個(gè)文件使用了php -v,結(jié)果下了我一跳,root用戶的版本是5.3.3,非root用戶是5.4.6,呵呵,我就呵呵了,誰部署的環(huán)境~,坑人啊.PHP教程

嘗試著將原有/usr/bin/php備份后,復(fù)制/usr/local/bin/php過來覆蓋掉,在使用php -v發(fā)現(xiàn)版本一致了,也不報(bào)錯(cuò)了,再次去執(zhí)行php protoc-php.php -n --psr dmp.proto,發(fā)現(xiàn)all is well,至此問題辦理.PHP教程

糾結(jié)了半天,結(jié)果便是版本的問題.PHP教程
