11.32 PHP Expansion Module installation

• This section learns how to install the PHP extension, as an example of installing a Redis module.
• 1. We can check if PHP has a redis module
  /usr/local/php7/bin/php-m |grep redis #查看php加载的模块
• 2. Download, unzip and install the Redis package
  Cd/usr /local/src/
  wget https://codeload.github.com/phpredis/phpredis/zip/develop
  MV Develop Phpredis-develop.zip
  Unzip phpredis-develop.zip
  CD Phpredis-develop
• The following is a generated configure file because does not have a configure file by default :
  /usr/local/php7/bin/phpize
  
• Configure, compile, and install Redis:
  ./configure--with-php-config=/usr/local /php7/bin/php-config
  Make && do install
• View Extension directory, we can customize the path in php.ini
  /usr/local/php7/ Bin/php-i |grep extension_dir
  
• Fix the PHP configuration file to load the newly installed modulo fast:
  Vim/usr/local/php7/etc/php.ini
• Add a line configuration (you can put it to the last line of the file)
  Extension = redis.so
  

• View loading results:
  /usr/local/php7/bin/php-m|grep redis
  

• In addition, the PHP source package comes with some extensions that are available for installation, which are located in the
  /usr/local/src/php-7.1.6/ext
  
  If the module exists in the directory, you do not need to go to the Internet to download, direct installation can be.

Summarize:

  CD into the module directory to install--->phpize generate configure files--->configure,make && make instal--->php.ini load modules---> View validation Load Results
