php-fpm
一.php-fmp 的pool
1.给不同的站点分别配置不同的pool
ps -ef |grep php查看信息

cd /usr/local/php-fpm/etc/(进入配置目录)
vim php-fpm.conf（添加一个配置文件）
[www] listen = /tmp/php-fcgi.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 [123.com] listen = /tmp/123.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（检查一下）
/etc/init.d/php-fpm restart（重启）
Gracefully shutting down php-fpm . done
Starting php-fpm done
ps -aux |grep php（查看信息）

cd /usr/local/nginx/conf/vhost/
vim default.conf（主要注意
fastcgi_pass unix:/tmp/123.sock；地址是否正确
）
server
{
listen 80 default_server;
server_name aaa.com;
index index.html index.htm index.php;
root /data/nginx/default;
location ~ \.php$ {
include fastcgi_params;
fastcgi_pass unix:/tmp/123.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /data/nginx/test.com$fastcgi_script_name;
}
}
/usr/local/nginx/sbin/nginx -t
/usr/local/nginx/sbin/nginx -s reload
2.配置拆分多个pool
cd /usr/local/php-fpm/etc/
vim php-fpm.conf
[global] pid = /usr/local/php-fpm/var/run/php-fpm.pid error_log = /usr/local/php-fpm/var/log/php-fpm.log include = etc/php-fpm.d/*.conf 加入一行：
include = etc/php-fpm.d/*.conf
创建存放配置文件的目录
mkdir php-fpm.d
cd php-fpm.d/
vim 123.conf
[123.com] listen = /tmp/123.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 www.conf
[www] listen = /tmp/php-fcgi.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
/etc/init.d/php-fpm restart(重启)
ls /tmp/*.sock
/tmp/123.sock /tmp/mysql.sock /tmp/php-fcgi.sock
ps -ef |grep php
3.慢执行文件
vim /usr/local/php-fpm/etc/php-fpm.d/www.conf
添加俩行代码：
request_slowlog_timeout = 1 slowlog = /usr/local/php-fpm/var/log/www-slow.log
/usr/local/php-fpm/sbin/php-fpm -t
/etc/init.d/php-fpm reload（重启）
ls /usr/local/php-fpm/var/log/
php-fpm.log www-slow.log
cat /usr/local/php-fpm/var/log/www-slow.log（什么都没是空的）
vim /data/nginx/test.com/sleep.php（写一个慢执行文件）
<?php echo "test slow log"; sleep(2); echo "done"; ?>
curl -x127.0.0.1:80 test.com/sleep.php
cat /usr/local/php-fpm/var/log/www-slow.log
[19-Aug-2021 10:27:09] [pool www] pid 3243 script_filename = /data/nginx/test.com/sleep.php [0x00007feda8c3c288] sleep() /data/nginx/test.com/sleep.php:3
4.php-fpm定义open_basedir
vim /usr/local/php-fpm/etc/php-fpm.d/www.conf
php_admin_value[open_basedir]=/data/nginx/wwwtest.com:/tmp/（故意配错）
/etc/init.d/php-fpm restart(重启)
ls /data/nginx/test.com/
curl -x127.0.0.1:80 test.com/sleep.php -I
HTTP/1.1 404 Not Found Server: nginx/1.17.8 Date: Mon, 13 Sep 2021 13:01:03 GMT Content-Type: text/html; charset=UTF-8 Connection: keep-alive X-Powered-By: PHP/5.6.30
curl -x127.0.0.1:80 test.com/3.php -I
HTTP/1.1 404 Not Found Server: nginx/1.17.8 Date: Mon, 13 Sep 2021 13:02:25 GMT Content-Type: text/html; charset=UTF-8 Connection: keep-alive X-Powered-By: PHP/5.6.30
vim /usr/local/php-fpm/etc/php-fpm.d/www.conf(改回来)
php_admin_value[open_basedir]=/data/nginx/test.com:/tmp
/etc/init.d/php-fpm restart(重启)
curl -x127.0.0.1:80 test.com/3.php -I
HTTP/1.1 200 OK Server: nginx/1.17.8 Date: Mon, 13 Sep 2021 13:05:53 GMT Content-Type: text/html; charset=UTF-8 Connection: keep-alive X-Powered-By: PHP/5.6.30
curl -x127.0.0.1:80 test.com/sleep.php -I
HTTP/1.1 200 OK Server: nginx/1.17.8 Date: Mon, 13 Sep 2021 13:06:32 GMT Content-Type: text/html; charset=UTF-8 Connection: keep-alive X-Powered-By: PHP/5.6.30
5.配置错误日志
vim /usr/local/php-fpm/etc/php.ini
display_errors = Off
log_errors = On
error_log = /usr/local/php-fpm/var/log/php_error.log ;
error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT
error_reporting = E_ALL
vim /usr/local/php-fpm/etc/php-fpm.d/www.conf（配置错误文件）
创建日志文件并且授权
touch /usr/local/php-fpm/var/log/php_error.log
chmod 777 /usr/local/php-fpm/var/log/php_error.log
curl -x127.0.0.1:80 test.com/3.php -I
状态码是404
curl -x127.0.0.1:80 test.com/sleep.php -I
状态码是404
curl -x127.0.0.1:80 test.com/sleep.php（显示open_basedir限制生效，目录不能访问）
cat /usr/local/php-fpm/var/log/php_error.log
[19-Aug-2021 03:21:22 UTC] PHP Warning: Unknown: open_basedir restriction in effect. File(/data/nginx/test.com/3.php) is not within the allowed path(s): (/data/nginx/wwwtest.com:/tmp/) in Unknown on line 0 [19-Aug-2021 03:21:22 UTC] PHP Warning: Unknown: failed to open stream: Operation not permitted in Unknown on line 0 [19-Aug-2021 03:21:32 UTC] PHP Warning: Unknown: open_basedir restriction in effect.

File(/data/nginx/test.com/sleep.php) is not within the allowed path(s): (/data/nginx/wwwtest.com:/tmp/) in Unknown on line 0 [19-Aug-2021 03:21:45 UTC] PHP Warning: Unknown: failed to open stream: Operation not permitted in Unknown on line 0
将配置文件改回来之后在重启服务PHP就会正常。
