需要放开 /usr/local/php/etc/php.ini 中的几个函数：proc_open,proc_get_status
disable_functions = passthru,exec,system,chroot,chgrp,chown,shell_exec,proc_open,proc_get_status,popen,ini_alter,ini_restore,dl,openlog,syslog,readlink,symlink,popepassthru,stream_socket_server重启 php-fpm 即可。
composer 安装
php -r "copy('https://install.phpcomposer.com/installer', 'composer-setup.php');"
php composer-setup.php
# 移动到全局范围
mv composer.phar /usr/local/bin/composer
# 更新 composer
composer selfupdate
