安装php-driver(PECL 安装不起作用.我认为这是因为只有 php7 设置)

git clone https://github.com/datastax/php-driver.gitcd php 驱动程序git子模块更新--init光盘分机./install.sh进行测试->所有测试通过

将驱动程序添加到 PHP 扩展

echo -e ";DataStax PHP 驱动

extension=cassandra.so" >>/etc/php/7.0/fpm/php.ini

重启nginx和php7.0-fpm

服务 nginx 重启服务 php7.0-fpm 重启

问题:

如果我想使用下面的代码，它会说我找不到类 Cassandra.网页:https://github.com/datastax/php-driver#datastax-php-driver-for-apache-cassandra

$cluster = Cassandra::cluster()->build();

感谢您的帮助.

解决方案

由于您尝试使用 nginx+fpm 执行 PHP 脚本，您需要更新相应的 php.ini 文件(例如 /etc/php7/fpm/php.ini).

将驱动模块添加到您的 nginx+fpm 安装中

echo -e ";DataStax PHP 驱动
extension=cassandra.so" >>/etc/php/7.0/fpm/php.ini

为确保通过 CLI 正确加载驱动程序，您可以执行以下操作:

php -m |grep 卡桑德拉

或

php -i |grep -A 10 "^cassandra$"

php -m 将打印出 PHP 能够加载的所有扩展/模块，而 php -i 将显示有关您的 PHP 安装配置的更详细信息.

I've done the installation process as following:

Installation Cassandra Datatrax

curl -L http://debian.datastax.com/debian/repo_key | sudo apt-key add -
apt install cassandra dsc30

Check services

Installation php-driver (PECL Installation isn't working. I think it's because of only php7 setup)

git clone https://github.com/datastax/php-driver.git
cd php-driver
git submodule update --init
cd ext
./install.sh
make test -> all tests passed

Add Driver to PHP Extensions

echo -e "; DataStax PHP Driver
extension=cassandra.so" >> /etc/php/7.0/cli/php.ini

// UPDATE - added extension to fpm/php.ini file.
echo -e "; DataStax PHP Driver
extension=cassandra.so" >> /etc/php/7.0/fpm/php.ini

Restart nginx and php7.0-fpm

service nginx restart
service php7.0-fpm restart

Question:

If I wanna use the following code it says me class Cassandra not found. Webpage: https://github.com/datastax/php-driver#datastax-php-driver-for-apache-cassandra

$cluster = Cassandra::cluster()->build();

Thank you for helping.

解决方案

Since you are trying to execute your PHP script using nginx+fpm you will need to update the appropriate php.ini file (e.g. /etc/php7/fpm/php.ini).

Add the driver module to your nginx+fpm installation

echo -e "; DataStax PHP Driver
extension=cassandra.so" >> /etc/php/7.0/fpm/php.ini

To ensure the the driver is being properly loaded via CLI you can execute the following:

php -m | grep cassandra

or

php -i | grep -A 10 "^cassandra$"

php -m will print out all the extension/modules that PHP was able to load whereas php -i will display more verbose information about your PHP installation configuration.
