Solution to the lack of libraries in PHP in Centos (this method is relatively violent, please do not imitate it unless it is a last resort!)

Origin of the problem: It is easy if the commonly used extensions when installing PHP are not added. If there is a lack of extensions, if you want to use yum to add extensions after long-term use, dependency problems will occur and you cannot install them. At this time, you can only try to download the software package yourself and install it through a series of commands: ./configure; make; make install; But at the end of the installation, it may give you a slap in the face and tell you that the installation failed! So here is a more violent method, which is to completely uninstall PHP and reinstall it with yum! ! !
The following will teach you how to completely uninstall. Use the following command to check what PHP-related installation packages are available
rpm -qa | grep php //If the past command does not work, just type it by hand
At this time A large number of installation packages below will be displayed
php-common-5.4.36-1.el6.remi.i686
php-xml-5.4.36-1.el6.remi.i686
php-pecl-apc-3.1.15-0.4.20130912.el6.remi.5.4.i686
php-fpm-5.4.36-1.el6.remi.i686
php-mysql-5.4.36 -1.el6.remi.i686
php-pear-1.9.5-3.el6.remi.noarch
mod-php-5.4-apache2-zend-server-5.4.34-17.i386
php-5.5-bin-zend-server-5.5.13-16.i386
php-bcmath-5.4.36-1.el6.remi.i686
php-pdo-5.4.36-1.el6 .remi.i686
php-gd-5.4.36-1.el6.remi.i686
php-dba-5.4.36-1.el6.remi.i686
php-process-5.4.36 -1.el6.remi.i686
Okay, after seeing the above, we can uninstall one by one...
sudo rpm --nodeps -e (package name) //Please try your best to uninstall it.
...
...
This time we can easily reinstall it
sudo yum --enablerepo=remi install php php-fpm php-mysql php-cli php-gd php -mcrypt php-xml php-dba php-pecl-apc //Add whatever you want
When installing, if you want to see the complete list of available PHP modules, you can run:
$ sudo yum -- enablerepo=remi search php-

Do you think this is the end? Obviously not, you also need to start the PHP-FPM service
$ sudo chkconfig php-fpm on
$ sudo service php-fpm start

Configure PHP

Next, Let's customize the PHP configuration file /etc/php.ini. More specifically, add the following two lines to the /etc/php.ini file.
cgi.fix_pathinfo=0
date.timezone="PRC"
