【配置】
php 配置文件路径:
/etc/php.ini
php-fpm 配置文件路径:
/etc/php-fpm.conf /etc/php-fpm.d/www.conf
编辑 php-fpm服务的配置文件 /etc/php-fpm.d/www.conf :
修改用户和组为nginx:
user = nginx group = nginx
创建目录 /run/php-fpm :
cd /run/ && mkdir php-fpm
编辑 /etc/init.d/php-fpm :
php_fpm_BIN=/usr/sbin/php-fpm php_fpm_CONF=/etc/php-fpm.conf php_fpm_PID=/run/php-fpm/php-fpm.pid
php-fpm 服务设置:
dos2unix 转换/设置执行权限/注册成服务/设置开机启动
dos2unix /etc/init.d/php-fpm && chmod a+x /etc/init.d/php-fpm && chkconfig --add php-fpm && chkconfig php-fpm on
使用 service 来启动 php-fpm:
service php-fpm start service php-fpm stop
【排错】
报错:connect() failed (111: Connection refused) while connecting to upstream … upstream: “fastcgi://127.0.0.1:9000”
查看 /etc/php-fpm.d/www.conf :
listen = /run/php-fpm/www.sock
或:
listen = 127.0.0.1:9000
编辑 nginx.conf :
# fastcgi_pass 127.0.0.1:9000; fastcgi_pass unix:/run/php-fpm/www.sock;
报错:open(SESSION_FILE, O_RDWR) failed: Permission denied (13)
phpMyAdmin报错。
mkdir /var/lib/php && mkdir /var/lib/php/session && chmod -R 777 /var/lib/php/session
如果目录存在却依然报错,尝试:
chmod -R 777 /var/lib/php/session
