Nginx PHP Warning: PHP Startup: Unable to load dynamic library

did you do as instructions in FAQ 39 and enable dynamic nginx modules in persistent config file at /etc/centminmod/custom_config.inc BEFORE recompiling nginx via centmin.sh menu option 4 ?

post the contents of your /etc/centminmod/custom_config.inc file

Code (Text):

cat /etc/centminmod/custom_config.inc

• What version of PHP used ? Did you upgrade or downgrade PHP recently ?
• If you upgraded and you get some PHP warnings that some PHP extensions are unable to load, all you need to do is delete the relevant *.ini files for them and then reinstall if you require the PHP extension. In your case it is memcache PHP extension so rerunning centmin.sh menu option 10 will reinstall it

Upgrading Centmin Mod Code to Latest Version

Getting Started Guide step 19 outlines also how to keep Centmin Mod code updated or how to switch version branches.

Centmin Mod LEMP stack's script code is constantly updated for improvements, bug fixes and security fixes so keeping the Centmin Mod code up to date is important. With Centmin Mod 1.2.3-eva2000.08) (123.08stable) and higher releases, a newly added centmin.sh menu option 23 allows much easier code updates and version branch swicthing via Git backed environment you can setup. For full details read the following links:

• New centmin.sh menu option 23 updating
• Centmin Mod Upgrades
• Cronjob Auto Updating Centmin Mod Code Guide
• How to upgrade Centmin Mod + backing up customisations

Upgrading Centmin Mod involves 2 parts.

1. Upgrading the actual Centmin Mod code outlined at Upgrade Centmin Mod. This is heart of Centmin Mod where the code is the engine that runs centmin.sh shell based menu and all the automation you're accustomed to. You can easily update within a Centmin Mod version branch or switch version branches via centmin.sh menu option 23 outlined here.
2. Upgrade software that Centmin Mod installed or manages. For this part following outline at How to upgrade Centmin Mod software installed on your server.

 

You might have hit the old zlib workaround bug with ccache so need to manually recompile ccache outlined at 123.09beta01 Updated Nginx zlib routine with optional Cloudflare zlib support

Code (Text):

export CC="gcc"
export CXX="g++"
cd /svr-setup/ccache-3.4.1/
make clean
./configure
make -j2
make install

the re-run centmin.sh

 

that is clearly incorrect filename foundtom_config.inc as no such file in centmin mod!

make sure your ssh client app is set to character encoding = UTF-8

run these command to run centmin.sh in debug mode and saved contents to /root/centminlogs/centmin-debug.txt. wait until you return to command prompt for completion of debug mode

Code (Text):

cmupdate
cd /usr/local/src/centminmod
echo 24 | bash -x centmin.sh 2>&1 | sed -e "s|$(hostname -f)|hostname|g" -e "s|$(hostname -s)|hostname|g" | tee /root/centminlogs/centmin-debug.txt

then post the contents of /root/centminlogs/centmin-debug.txt to pastebin.com or gist.github.com and share the link here or private message me with the link

 

fyi made slight revision to cmd

Code (Text):

cmupdate
cd /usr/local/src/centminmod
echo 24 | bash -x centmin.sh 2>&1 | sed -e "s|$(hostname -f)|hostname|g" -e "s|$(hostname -s)|hostname|g" | tee /root/centminlogs/centmin-debug.txt

 

ok found the problem in debug log seems you have an empty line break in /etc/centminmod/custom_config.inc on line 22 cause some problem - did you edit that file using linux text editor like vi or nano ? if you used local pc text editor it might not have been saved as unix/UTF-8 encoded file

/etc/centminmod/custom_config.inc: line 22:
: command not found

on local text editors save as linux/unix UTF-8 encoding or edit via vi or nano the /etc/centminmod/custom_config.inc persistent config file

for now use dos2unix to see if converting the file will remove those \r line breaks which were probably added by windows or pc editor

Code (Text):

dos2unix /etc/centminmod/custom_config.inc

might need to do something like this by default to save some problems
