OS X EI Capitan installs mcrypt ​ (Original text of my blog: http://www.jmolboy.com/2015/12/01/mcrypt-extension-on-EI-Capitan/) ​ December 01, 2015 Published in php extension

After the mac operating system was upgraded to 10.11.2 (OS Neither could be successfully installed; I was troubled for a long time. When installing after compilation, it always prompts

<span class="line">1</span>

<span class="line">[cp: /usr/lib/php/extensions/no-debug-non-zts-20121212/#INST@17000#: Operation not permitted]</span>

Finally found the problem

What the hell

When you enter the /usr/lib/php/extensions/ directory, you will find that the directory cannot be operated at all (manual copying and moving), and you do not have permission to use root in the terminal; but is it impossible? I am already a root user, why is it not allowed? It turns out that OSX 10.11 El Capitan has added a new security mechanism called System Integrity Protection (SIP), so for the directory

• /System
• /sbin
• /usr
• Does not contain (/usr/local/)

Only for system use, other users or programs cannot use it directly, and our /usr/lib/php/extensions/ happens to be within the protected scope

Ban SIP

So the solution is to disable the SIP protection mechanism. The steps are:

• Restart the system
• Hold Command R
• Menu "Utilities" ==>> "Terminal" ==>> Enter csrutil disable; after execution, it will output: Successfully disabled System Integrity Protection. Please restart the machine for the changes to take effect.
• Restart the system again

After disabling SIP, you can install it smoothly. Of course, you can re-enable SIP after installation. The method is the same as above, but the command is csrutil enable

Full installation

<span class="line">1</span>

<span class="line">cd ~ ; mkdir mcrypt ; cd mcrypt</span>

Download
libmcrypt2.5.8 and the php version of your system to the mcrypt directory

Unzip

<span class="line">1</span>

<span class="line">tar -zxvf libmcrypt-2.5.8.tar.gz tar -zxvf php-5.5.27.tar.gz rm *.gz</span>

Install libmcrypt

<span class="line">1</span>

<span class="line">cd libmcrypt-2.5.8 ./configure make sudo make install</span>

Install autoconf

<span class="line">1</span>

<span class="line">cd ~/mcrypt curl -O http://ftp.gnu.org/gnu/autoconf/autoconf-latest.tar.gz tar xvfz autoconf-latest.tar.gz cd autoconf-2.69/ ./configure make sudo make install</span>

Compile mcrypt php extension

<span class="line">1</span>

<span class="line">cd ../php-5.5.27/ext/mcrypt/ /usr/bin/phpize</span>

The above will output:

<span class="line">1</span>

<span class="line">Configuring for: PHP Api Version: 20121113 Zend Module Api No: 20121212 Zend Extension Api No: 220121212</span>

Then compile:

<span class="line">1</span>

<span class="line">./configure make sudo make install</span>

The above will output:

<span class="line">1</span>

<span class="line">Installing shared extensions: /usr/lib/php/extensions/no-debug-non-zts-20121212/</span>

If there is an error (that I encountered):

<span class="line">1</span>

<span class="line">cp: /usr/lib/php/extensions/no-debug-non-zts-20121212/#INST@17000#: Operation not permitted</span>

It means you need to disable SIP first (see above for how to disable SIP)

Modify /etc/php.ini and add extension=mcrypt.so

Restart apache

<span class="line">1</span>

<span class="line">sudo apachectl restart</span>

Look at your phpinfo(); mcrypt information will appear;
