php-fpm的pool、php-fpm慢執行日誌、open_basedir、php-fpm進程管理
php-fpm的pool
當很多php站點共用一個池的時候，若是其中一個站點影響了這個pool，會導致其他站點也出現問題，為避免這個問題發生，需要對每個站點新建一個pool，進行隔離，保障服務安全
1、[root@centos7 ~]# vim /usr/local/php-fpm/etc/php-fpm.conf
新增：
[test.com]
listen = /tmp/test.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
2、[root@centos7 ~]# /usr/local/php-fpm/sbin/php-fpm -t
3、[root@centos7 ~]# /etc/init.d/php-fpm reload
4、[root@centos7 ~]# vim /usr/local/nginx/conf/vhost/aaa.com.conf
5、新增如下：
[root@centos7 ~]# vim /usr/local/nginx/conf/vhost/aaa.com.conf.bak
server
{
listen 80 default_server;
#有‘default_server‘標記的就是默認虛擬主機
server_name aaa.com;
index index.html index.htm index.php;
root /data/wwwroot/default;
location ~ \.php$
{
include fastcgi_params;
fastcgi_pass unix:/tmp/test.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /data/wwwroot/default$fastcgi_script_name;
}
}
6、[root@centos7 ~]# /etc/init.d/nginx reload
7、可以看出有兩個pool了
[root@centos7 ~]# ps aux |grep php-fpm
php-fpm 8403 0.0 0.2 227144 4808 ? S 17:22 0:00 php-fpm: pool www
php-fpm 8423 0.0 0.2 227144 4812 ? S 17:22 0:00 php-fpm: pool test.com
添加php-fpm.conf子配置文件
為了方便管理php-fpm.conf上配置文件，類似於nginx上的虛擬主機conf，也可以分開填寫文件
1、
[root@centos7 php-fpm.d]# vi /usr/local/php-fpm/etc/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 = /usr/local/php-fpm.d/*.conf
2、
[root@centos7 php-fpm.d]# vim /usr/local/php-fpm.d/test.conf
[test.com]
listen = /tmp/test.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
3、
[root@centos7 php-fpm.d]# vim /usr/local/php-fpm.d/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
4、
[root@centos7 php-fpm.d]# /usr/local/php-fpm/sbin/php-fpm -t
5、
[root@centos7 php-fpm.d]# /etc/init.d/php-fpm reload
驗證：是否有2個pool
[root@centos7 php-fpm.d]# ps -ef | grep php-fpm
php-fpm慢執行日誌
當php訪問變慢時，可以通過慢日誌來查看是哪個php腳本導致，類似mysql的慢日誌
1、新增內容
[root@centos7 php-fpm.d]# vim /usr/local/php-fpm.d/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
request_slowlog_timeout = 1
#請求超過1秒就記錄到日誌裏
slowlog = /usr/local/php-fpm/var/log/www-slow.log
2、實驗腳本編寫
[root@centos7 php-fpm.d]# vim /data/wwwroot/test.com/sleep.php
#輸出test slow log，sleep2秒，結束
<?php
echo "test slow log";
sleep(2);
echo "done";
?>
[root@centos7 php-fpm.d]# /etc/init.d/php-fpm reload
3、驗證：
[root@centos7 php-fpm.d]# curl -x127.0.0.1:80 test.com/sleep.php
test slow logdone[root@cen
[root@centos7 php-fpm.d]# tail /usr/local/php-fpm/var/log/www-slow.log
#記錄了日誌
[16-Nov-2017 17:41:59] [pool www] pid 8669
script_filename = /data/wwwroot/test.com/sleep.php
[0x00007f15620aa2e8] sleep() /data/wwwroot/test.com/sleep.php:3
open_basedir設置
當一臺服務器跑多個站點時，使用open_basedir限定各個站點所能訪問的服務器上的目錄的範圍。在php-fpm服務中，可以針對每個pool設定open _ basedir。
1、新增內容
[root@centos7 php-fpm.d]# vim /usr/local/php-fpm.d/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
request_slowlog_timeout = 1
#請求超過1秒就記錄到日誌裏
slowlog = /usr/local/php-fpm/var/log/www-slow.log
php_admin_value[open_basedir]=/data/wwwroot/test.com:/tmp/
2、
[root@centos7 php-fpm.d]# vim /data/wwwroot/test.com/1.php
<?php
echo "This is open_basedir";
3、驗證:
[root@centos7 php-fpm.d]# /etc/init.d/php-fpm reload
Reload service php-fpm done
[root@centos7 php-fpm.d]# curl -x127.0.0.1:80 test.com/1.php
This is open_basedir
php-fpm進程管理
php-fpm中pool配置參數解析：
[root@adailinux php-fpm.d]# vim www.conf
[www]
listen = /tmp/php-fcgi.sock
listen.mode = 666
user = php-fpm
group = php-fpm
pm = dynamic
;定義進程啟動方式（dynamic表示動態，static表示靜態）
;只有此處設置為dynamic，下面的配置才生效，若是選擇靜態，會預先生產設定的進程，不會動態變化
pm.max_children = 50
;最多可啟動的子進程數量
pm.start_servers = 20
;設定初始啟動的進程數量
pm.min_spare_servers = 5
;表示php-fpm空閑時最少要有幾個子進程
pm.max_spare_servers = 35
;表示php-fpm空閑時最多要有幾個子進程
pm.max_requests = 500
;表示一個子進程最多可接受多少個請求
rlimit_files = 1024
;表示每個子進程打開的多少個文件句柄
request_slowlog_timeout = 1
;當請求超過1秒開始記錄日誌
slowlog = /usr/local/php-fpm/var/log/www-slow.log
;日誌存放地址
php_admin_value[open_basedir]=/data/wwwroot/test.com:/tmp/
