Laravel composer install 缺少phpfile_info，LNMP安装PHP fileinfo扩展模块

# 安装composer

这里不解释了

# 执行

 

 Problem 1
    - Installation request for league/flysystem 1.0.50 -> satisfiable by league/flysystem[1.0.50].
    - league/flysystem 1.0.50 requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.
  Problem 2
    - league/flysystem 1.0.50 requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.
    - laravel/framework v5.7.26 requires league/flysystem ^1.0.8 -> satisfiable by league/flysystem[1.0.50].
    - Installation request for laravel/framework v5.7.26 -> satisfiable by laravel/framework[v5.7.26].

  To enable extensions, verify that they are enabled in your .ini files:
    - /usr/local/php/etc/php.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
 

解决：

安装PHP程序的时候，提示The fileinfo extension is required.，缺少fileinfo 扩展，因为LNmpA没有自行开启，所以需要我们手工去开启fileinfo 扩展。

 

方法如下：
第一步：找到llnmp安装源位置：

cd /lnmp1.5/src/php-5.6.9/ext/fileinfo/

 （如果php包没解压，那就解压）

第二步：

/usr/local/php/bin/phpize

返回类似下面的信息：

Configuring for:

PHP Api Version:         20131106

Zend Module Api No:      20131226

Zend Extension Api No:   220131226

phpize是什么东西呢？
php官方的说明：http://php.net/manual/en/install.pecl.phpize.php
phpize是用来扩展php扩展模块的，通过phpize可以建立php的外挂模块，比如你想在原来编译好的php中加入memcached或者ImageMagick等扩展模块，可以使用phpize。

 

第三步：

./configure --with-php-config=/usr/local/php/bin/php-config
make && make install

返回类似下面信息：

Build complete.

Don't forget to run 'make test'.

Installing shared extensions:     /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/

表明安装成功了。

 

第四步：
/usr/local/php/etc/php.ini 添加扩展：

extension=fileinfo.so

/etc/init.d/php-fpm restart

#然后重新执行composer

composer install

 

OK，成功

#composer install 报错总结：

  [ErrorException]                                         
  proc_get_status() has been disabled for security reasons

#解决：

[root@minion1 attendize]# grep proc_get_status /usr/local/php/etc/php.ini
disable_functions = passthru,exec,system,chroot,scandir,chgrp,chown,shell_exec,proc_get_status,popen,ini_alter,ini_restore,dl,openlog,syslog,readlink,symlink,popepassthru,stream_socket_server

找到proc_get_status删除，重启php

/etc/init.d/php-fpm restart

 

记得 make test
