It appeared to me today when installing wordpress using hestiacp

Downloading from https://github.com/wp-cli/wp-cli/releases/download/v2.12.0/wp-cli-2.12.0.phar… md5 hash verified: a592bbf68fc5143bfad5800cb4947253 Error: Cannot do ‘Process::run’: The PHP functions proc_open() and/or proc_close() are disabled. Please check your PHP ini directive disable_functions or suhosin settings. Error: cmd exited with errors

I solved it in the php ini editor

Before
disable_functions = pcntl_alarm,pcntl_fork,pcntl_waitpid,pcntl_wait,pcntl_wifexited,pcntl_wifstopped,pcntl_wifsignaled,pcntl_wifcontinued,pcntl_wexitstatus,pcntl_wtermsig,pcntl_wstopsig,pcntl_signal,pcntl_signal_dis patch,pcntl_get_last_error,pcntl_strerror,pcntl_sigprocmask,pcntl_sigwaitinfo,pcntl_sigtimedwait,pcntl_exec,pcntl_getpriority,pcntl_setpriority,exec,system,passthru,shell_exec,proc_open,popen

After
disable_functions = pcntl_alarm,pcntl_fork,pcntl_waitpid,pcntl_wait,pcntl_wifexited,pcntl_wifstopped,pcntl_wifsignaled,pcntl_wifcontinued,pcntl_wexitstatus,pcntl_wtermsig,pcntl_wstopsig,pcntl_signal,pcntl_ signal_dispatch,pcntl_get_last_error,pcntl_strerror,pcntl_sigprocmask,pcntl_sigwaitinfo,pcntl_sigtimedwait,pcntl_exec,pcntl_getpriority,pcntl_setpriority,exec,system,passthru,shell_exec

I removed proc_open,popen from that list and wp reinstalled it.
I don’t know why wp stopped installing, nor why this appeared or if the code was already like this

I would like to know if this influences other things in Hestia PHP, etc. If not, that’s fine, I’ll leave it like this.

proc_open and other functions are disabled by default when using php fpm but using php cli, proc_open should be enabled.

To check if proc_open is disabled in cli (if you get no output, the function is enabled):

grep -r proc_open /etc/php/*/cli/

To check if proc_open is disabled in fpm (you should see the function disabled):

grep -r proc_open /etc/php/*/fpm/

If proc_open is disabled in cli, execute this command:

sudo /usr/local/hestia/install/upgrade/manual/secure_php.sh
