PHP 7：MongoDB 驱动程序问题

Question

我在尝试安装 MongoDB PHP 库时遇到了错误：

$ composer require "mongodb/mongodb=^1.0.0"

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/mongodb.so' - /usr/lib/php/20151012/mongodb.so: undefined symbol: php_json_serializable_ce in Unknown on line 0
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/mongodb.so' - /usr/lib/php/20151012/mongodb.so: undefined symbol: php_json_serializable_ce in Unknown on line 0
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/mongodb.so' - /usr/lib/php/20151012/mongodb.so: undefined symbol: php_json_serializable_ce in Unknown on line 0
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/mongodb.so' - /usr/lib/php/20151012/mongodb.so: undefined symbol: php_json_serializable_ce in Unknown on line 0

当我执行phpinfo() 时，我可以看到以下内容：

mongodb

mongodb support enabled
mongodb version 1.2.1
mongodb stability   stable
libmongoc version   1.5.0
libbson version 1.5.0

当我执行 locate mongodb.so 时，这是我的 mongodb.so 文件所在的位置：

/usr/lib/php/20151012/mongodb.so

我注意到，这是20-mongodb.ini 文件所在的路径：

/etc/php/7.0/apache2/conf.d

另外，sudo pecl mongodb install 返回以下内容：

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/mongodb.so' - /usr/lib/php/20151012/mongodb.so: undefined symbol: php_json_serializable_ce in Unknown on line 0

sudo pecl info mongodb 返回：

我在 Google 上搜索了几个小时，但仍然一无所获。谢谢。

Answer 1

首先键入此命令/usr/bin/php-config 以查看扩展目录的位置。
你会看到类似--extension-dir [/usr/lib/php/20131226] 比那个文件夹中的ls 看看mongo.so 是否在那里，如果没有把它放在那里。
键入whereis php 以在CLI 中找到您正在使用的php
编辑 CLI 的 php.ini 并添加 extension=mongo.so

Answer 2

使用1.1.9 mongodb版本：

sudo pecl uninstall mongodb
sudo pecl install mongodb-1.1.9
composer update

Answer 3

是的，有很好的答案。 这是我在 php7.1 中安装 mongo 所做的。我正在使用 ubuntu16.04 64bit：

sudo aptitude install -y php7.1-dev pkg-config
sudo -H pecl channel-update pecl.php.net
sudo aptitude install -y libcurl4-openssl-dev pkg-config libssl-dev libsslcommon2-dev
sudo pecl install mongodb
echo 'extension=mongodb.so' | sudo tee /etc/php/7.1/fpm/conf.d/30-mongodb.ini
echo 'extension=mongodb.so' | sudo tee /etc/php/7.1/cli/conf.d/30-mongodb.ini
sudo systemctl restart php7.1-fpm.service

这一切都是为了 nginx。如果您使用的是apache，请添加：

echo 'extension=mongodb.so' | sudo tee /etc/php/7.1/apache2/conf.d/30-mongodb.ini

还有一个。如果您在使用 mongo 时仍然出现错误。类似的东西：

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/20160303/mongodb.so' - libssl.so.1.0.2: cannot open shared object file: No such file or directory in Unknown on line 0

不要绝望，运行以下命令：

sudo pecl uninstall mongodb
sudo pecl install mongodb

Answer 4

我是 @Andrinux 和 @J.C. Gras 的建议，我收到了一个错误 phpize not found。

所以我做了研究，发现了这个How to install and run phpize。这是因为我的系统上没有安装php-dev，所以我安装了它。

按顺序，我做到了：

// Ubuntu 20.04.3
$ sudo apt-get update
$ sudo apt install php-dev
$ sudo pecl install mongodb (at the time, it installed mongodb-1.10.0)

如果您看到此消息，则扩展程序已成功安装

Don't forget to run 'make test'.

You should add "extension=mongodb.so" to php.ini

别忘了重启 PHP-FPM 和 APACHE 服务器
