What should I do if the php extension installation does not take effect?

Solution to the problem that the php extension installation does not take effect: 1. Specify the php.ini file to start the php-fpm service; 2. Check and modify the php.ini file, and then restart the php-fpm service.

After php installs the extension module, it cannot restart Reasons for effectiveness and solutions

In the lnmp operation and maintenance environment, we often encounter that some extension modules that PHP depends on are not installed, which requires subsequent addition of these extension modules. After the extensions are installed and configured, you will often find that after the php-fpm service is restarted, these extensions are not actually loaded! The following is an example to illustrate:

Sample environment:

php installation package storage path: /data/software/php -5.6.10.tar.gz

php installation directory:/data/php

[root@zabbix ~]# ll /data/software/php-5.6.10.tar.gz
-rw-r--r-- 1 root root 18306403 6月 11 2015 /data/software/php-5.6.10.tar.gz
[root@zabbix ~]# ll -d /data/software/php-5.6.10
drwxr-xr-x 17 www www 4096 10月 13 19:38 /data/software/php-5.6.10
[root@zabbix ~]# ls /data/php/
bin etc include lib php sbin var

Using the php -m command, it is found that the bcmath and gettest extensions are missing

[root@zabbix ~]# vim /etc/profile
export PATH=$PATH:/data/php/bin
[root@zabbix ~]# source /etc/profile
[root@zabbix ~]# php -m|grep bcmath
[root@zabbix ~]# php -m|grep gettext
[root@zabbix ~]#

Now start installing bcmatn and gettest extensions

Install bcmath extension

[root@zabbix ~]# cd /data/software/php-5.6.10/ext/bcmath/
[root@zabbix bcmath]# /data/php/bin/phpize
[root@zabbix bcmath]# ./configure --with-php-config=/data/php/bin/php-config
[root@zabbix bcmath]# make && make
.......

After successful compilation, you will be informed of a directory

Installing shared extensions:   /data/php/lib/php/extensions/no-debug-non-zts-20131226

Install gettext extension

[root@zabbix ~]# cd /data/software/php-5.6.10/ext/gettext/
[root@zabbix gettext]# /data/php/bin/phpize
[root@zabbix gettext]# ./configure --with-php-config=/data/php/bin/php-config
[root@zabbix gettext]# make && make
.......

After successful compilation, you will be informed of a directory [Recommended study: "PHP Video Tutorial"]

Installing shared extensions:   /data/php/lib/php/extensions/no-debug-non-zts-20131226
[root@zabbix ~]# ll /data/php/lib/php/extensions/no-debug-non-zts-20131226

Total usage 2336

-rwxr-xr-x 1 root root 380152 10月 13 23:03 bcmath.so
-rwxr-xr-x 1 root root  50376 10月 13 23:31 gettext.so

Configure php.ini

[root@zabbix ~]# vim /data/php/etc/php.ini
.........
extension_dir = "/data/php/lib/php/extensions/no-debug-non-zts-20131226"
extension=bcmath.so
extension=gettext.so

Restart php-fpm

[root@zabbix ~]# /etc/init.d/php-fpm restart
Gracefully shutting down php-fpm . done
Starting php-fpm done

Then check again whether the bcmath and gettext extensions have taken effect after installation?

[root@zabbix ~]# php -m|grep bcmath
[root@zabbix ~]# php -m|grep gettext
[root@zabbix ~]#

Found that it didn’t take effect! why! ?

This is because php.ini was not specified when php-fpm was started, so it never took effect!

[root@zabbix etc]# /etc/init.d/php-fpm restart
Gracefully shutting down php-fpm . done
Starting php-fpm done
[root@zabbix etc]# ps -ef|grep php-fpm
root   19529   1 0 23:37 ?    00:00:00 php-fpm: master process (/data/php/etc/php-fpm.conf)
www   19530 19529 0 23:37 ?    00:00:00 php-fpm: pool www
www   19531 19529 0 23:37 ?    00:00:00 php-fpm: pool www
root   19533 17173 0 23:37 pts/4  00:00:00 grep --color=auto php-fpm

Solution:

1) Specify the php.ini file to start the php-fpm service

[root@zabbix etc]# /etc/init.d/php-fpm stop
Gracefully shutting down php-fpm . done
[root@zabbix etc]# ps -ef|grep php-fpm
root   19541 17173 0 23:38 pts/4  00:00:00 grep --color=auto php-fpm
[root@zabbix etc]# /data/php/sbin/php-fpm -y /data/php/etc/php-fpm.conf -c /data/php/etc/php.ini
[root@zabbix etc]# ps -ef|grep php-fpm
root   19543   1 0 23:38 ?    00:00:00 php-fpm: master process (/data/php/etc/php-fpm.conf)
www   19544 19543 0 23:38 ?    00:00:00 php-fpm: pool www
www   19545 19543 0 23:38 ?    00:00:00 php-fpm: pool www
root   19547 17173 0 23:39 pts/4  00:00:00 grep --color=auto php-fpm

2) If after starting the above, the installed php extension still does not take effect! Then it may be that the php.ini file is not placed in the right path (here I directly enlarge the etc directory of php)

[root@zabbix ~]# ll /data/php/etc/php.ini
-rw-r--r-- 1 root root 73243 10月 13 23:32 /data/php/etc/php.ini
[root@zabbix ~]# cp /data/php/etc/php.ini /data/php/lib/
[root@zabbix ~]# ll /data/php/lib/php.ini
-rw-r--r-- 1 root root 73243 10月 13 23:35 /data/php/lib/php.ini

Then restart the php-fpm service!

[root@zabbix ~]# /etc/init.d/php-fpm restart
Gracefully shutting down php-fpm . done
Starting php-fpm done
[root@zabbix ~]# ps -ef|grep php
root   19564   1 0 23:43 ?    00:00:00 php-fpm: master process (/data/php/etc/php-fpm.conf)
www   19565 19564 0 23:43 ?    00:00:00 php-fpm: pool www
www   19566 19564 0 23:43 ?    00:00:00 php-fpm: pool www
root   19568 17173 0 23:43 pts/4  00:00:00 grep --color=auto php
[root@zabbix ~]#

Finally check again whether the bcmath and gettext extensions have taken effect?

[root@zabbix ~]# php -m|grep bcmath
bcmath
[root@zabbix ~]# php -m|grep gettext
gettext
[root@zabbix ~]#
