Install igbinary

1. 安裝
• 透過PECL
  

  pecl install igbinary

• 透過Source Code
1. 下載igbinary.tgz
   

   wget https://pecl.php.net/get/igbinary-2.0.0.tgz
   

2. Install
   

   #1 以igbinary-2.0.0.tgz為例
   cd {install}/ 
   #安裝igbinary-2.0.0.tgz
   $ tar zxvf igbinary-2.0.0.tgz
   $ cd igbinary-2.0.0..tgz/
   $ phpize
   $ ./configure
   $ make && make install

   如果./configure出現 no acceptable C compiler found in $PATH 需安裝gcc
2. 檢查是否有igbinary.so
   

   $ ll /usr/lib64/php/modules/ | grep igbinary.so  
   -rwxr-xr-x 1 root root 312644 Dec 20 07:40 igbinary.so

3. 編輯將igbinary.ini
   

    $ vi /etc/php.d/igbinary.ini 
    ============= 我是分隔線 =================  
   ; Enable igbinary extension module 
    extension=igbinary.so 
    ; Enable or disable compacting of duplicate strings  
   ; The default is On.  igbinary.compact_strings=On 
    ; Use igbinary as session serializer 
    session.serialize_handler=igbinary 
    ; Use igbinary as APC serializer 
    apc.serializer=igbinary    # php7後，還沒試過

4.  重新啟動apache
   

    $ service httpd restart 
    $ php -m | grep igbinary #檢查是否安裝成功 
    igbinary
