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

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
Copy after login
One definition:
[root@shuai-01 vhost]# vi test.com.conf

## One definition:
[root@shuai-01 vhost]# vi aaa.com.conf

Method 2:
The first method appears Not tidy enough. It can be similar to the include statement when adding a virtual machine in nginx.
Add content in /usr/local/php-fpm/etc/php-fpm.conf:
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
Copy after login
Slow execution log
php-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
Copy after login
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
Copy after login
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
Copy after login
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
Copy after login
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/
Copy after login
