This article introduces the content of php-fpm pool, PHP slow execution log, open_basedir, and php-fpm process management. It has certain reference value. Now I share it with you. Friends in need can refer to it
Pool configuration of php-fpm
Multiple virtual machines can be opened in nginx, and they all require PHP to provide services, so in order to ensure that each different virtual machine Performance, multiple php-fpm pool services can be enabled. Each pool serves one site.
Method 1:
Add content in /usr/local/php-fpm/etc/php-fpm.conf:
//两个模块命名为不同名字，监听的socket名字也不一样。在vhost相应的conf的中设置对应路径即可。 [www] listen = /tmp/www.sock listen.mode=666 user = php-fpm group = php-fpm pm = dynamic pm.max_children = 50 pm.start_servers = 20 pm.min_spare_servers = 5 pm.max_spare_servers = 35 pm.max_requests = 500 rlimit_files = 1024 [shuai。com] listen = /tmp/shuai.sock listen.mode=666 user = php-fpm group = php-fpm pm = dynamic pm.max_children = 50 pm.start_servers = 20 pm.min_spare_servers = 5 pm.max_spare_servers = 35 pm.max_requests = 500 rlimit_files = 1024 /usr/local/php-fpm/sbin/php-fpm -t //验证配置是否正确 service php-fpm restart //重启 [root@shuai-01 etc]# ps aux |grep php-fpm root 5854 1.2 0.4 227212 4972 ?

Use pool:
[root@shuai-01 etc]# cd /usr/local/nginx/conf/vhost/ [root@shuai-01 vhost]# ls aaa.com.conf ld.conf proxy.conf ssl.conf test.com.conf
One definition:
[root@shuai-01 vhost]# vi test.com.conf
[root@shuai-01 vhost]# vi aaa.com.conf
The first method appears Not tidy enough. It can be similar to the include statement when adding a virtual machine in nginx.
include = etc/php-fpm.d/*.conf
Then delete the following configuration statement.
mkdir /usr/local/php-fpm/etc/php-fpm.d/ cd /usr/local/php-fpm/etc/php-fpm.d/ vim www.conf //内容如下 [www] listen = /tmp/www.sock listen.mode=666 user = php-fpm group = php-fpm pm = dynamic pm.max_children = 50 pm.start_servers = 20 pm.min_spare_servers = 5 pm.max_spare_servers = 35 pm.max_requests = 500 rlimit_files = 1024 vim aming.conf //内容如下 [aming] listen = /tmp/aming.sock //监听的sock名字互不相同 listen.mode=666 user = php-fpm group = php-fpm pm = dynamic pm.max_children = 50 pm.start_servers = 20 pm.min_spare_servers = 5 pm.max_spare_servers = 35 pm.max_requests = 500 rlimit_files = 1024 //检查vhost的conf文件，相应的更改监听sock /usr/local/php-fpm/sbin/php-fpm -t //验证配置是否正确 service php-fpm restart //重启 ps aux |grep php-fpm //发现aming和www都出现了Slow execution logphp-fpm has a very useful function, which is the slow execution log. It can be used very effectively to diagnose system problems. Especially when system access is slow. vim /usr/local/php-fpm/etc/php-fpm.d/www.conf
//Add the following content
request_slowlog_timeout = 1 //Record statements executed for more than one second Come down, in the production environment, it usually takes 2 seconds to write here
slowlog = /usr/local/php-fpm/var/log/www-slow.log //Log storage directory
vim /data/wwwroot/test.com/sleep.php //写入如下内容 <?php echo "test slow log"; sleep(2); echo "done"; ?> [root@cent01 vhost]# curl -x127.0.0.1:80 test.com/sleep.php //测试During testing A 502 error occurs, and the *.sock monitored in the pool is different from the main configuration file.
test slow logdone [root@cent01 vhost]# cat /usr/local/php-fpm/var/log/www-slow.log //慢日志提示第三行花费的时间太多 [16-Nov-2017 20:20:39] [pool www] pid 14208 script_filename = /data/nginx/test.com/sleep.php [0x00007f630f62f270] sleep() /data/nginx/test.com/sleep.php:3
当php文件遇到错误时，查错可以在/etc/init.d/php-fpm.ini 文件中打开display_error功能，这样错误就能直接在浏览器上显示。
open_basedir
open_basedir如果在php.ini中定义就不合适，在pool中定义刚刚好，在Apache中定义在虚拟主机配置文件。
可以直接在/usr/local/php-fpm/etc/php-fpm.d/www.conf中添加如下语句：
php_admin_value[open_basedir]=/data/nginx/aming.com:/tmp/
配置完成后重启服务 service php-fpm restart 或者 /etc/init.d/php-fpm restart
其中路径需要配置正确。否则会报错。
将配置文件改为如下几行。
[root@shuai-01 php-fpm.d]# vi /usr/local/php-fpm/etc/php.ini error_log=/usr/local/php-fpm/var/log/php_errors.log error_reporting=E_ALL display_errors = Off log_errors = On
创建一个存放错误日志的文件
[root@shuai-01 php-fpm.d]# touch /usr/local/php-fpm/var/log/php_errors.log [root@shuai-01 php-fpm.d]# chmod 777 /usr/local/php-fpm/var/log/php_errors.log
php-fpm进程管理
[root@shuai-01 php-fpm.d]# cat www.conf [www] listen = /tmp/www.sock listen.mode=666 user = php-fpm group = php-fpm pm = dynamic //动态的 ;pm = static pm.max_children = 50 //最大子进程50个 pm.start_servers = 20 // 启动的时候20个 pm.min_spare_servers = 5 //空闲时，最少有5个 pm.max_spare_servers = 35 //空闲时，最大有35个 pm.max_requests = 500 // 一个进程最多的请求数 rlimit_files = 1024 request_slowlog_timeout = 1 slowlog = /usr/local/php-fpm/var/log/www-slow.log php_admin_value[open_basedir]=/data/wwwroot/test.com:/tmp/
