50次课 php-fpm的（pool慢执行日志open_basedir进程管理）

Posted 2020-12-30

php-fpm的pool

它的pool就是它的池子

[[email protected] etc]# cd /usr/local/php-fpm/etc/
[[email protected] etc]# ls
pear.conf  php-fpm.conf  php-fpm.conf.default  php.ini
[[email protected] etc]# cat 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
[www]
 listen = /tmp/php-fcgi.sock
#listen = 127.0.0.1:9000
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

设置多个pool

* 进入/usr/local/php-fpm/etc/下编辑php-fpm.conf

[[email protected] etc]# cd /usr/local/php-fpm/etc/
[[email protected] etc]# ls
pear.conf  php-fpm.conf  php-fpm.conf.default  php.ini
[[email protected] etc]# vim php-fpm.conf

以上添加完成后查看是否有语法错误

[[email protected] etc]# /usr/local/php-fpm/sbin/php-fpm -t
[17-Aug-2018 11:03:39] NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful

没有语法错误然后重启

[[email protected] etc]# /etc/init.d/php-fpm reload
Reload service php-fpm  done

然后用ps看一下

[[email protected] etc]# ps aux |grep php-fpm

怎么用两个pool

进入 /usr/local/nginx/conf/vhost/目录下编辑test.com.conf

[[email protected] etc]# cd /usr/local/nginx/conf/vhost/
[[email protected] vhost]# ls
aaa.com.conf  ld.conf  proxy.conf  ssl.conf  test.com.conf
[[email protected] vhost]# vim test.com.conf 

[[email protected] vhost]# vim test.com.conf

    expires 7d;
    valid_referers none blocked server_names  *.test.com ;
    if ($invalid_referer) {
        return 403;
    }
    access_log off;
}
    location ~ .*.(js|css)$
    {
#          expires      12h;
          access_log off;
    }
    location /admin/
    {
      allow 192.168.63.100;
      allow 127.0.0.1;
      deny all;
      }

    location ~ .*(upload|image)/.*.php$
    {
        deny all;
    }
    if ($http_user_agent ~* ‘Spider/3.0|YoudaoBot|Tomato‘)
    {
      return 403;
    }
    location ~ .php$
    {
        include fastcgi_params;
        fastcgi_pass unix:/tmp/php-fcgi.sock;      ##**这里定义成php-fcgi.sock**
        #fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME /data/wwwroot/test.com$fastcgi_script_name;
    }

    access_log /tmp/test.com.log hanshuo;
}

然后再去定义另外一个pool

[[email protected] vhost]# ls
aaa.com.conf  ld.conf  proxy.conf  ssl.conf  test.com.conf

[[email protected] vhost]# vim aaa.com.conf

[[email protected] vhost]# vim aaa.com.conf

server
{
    listen 80 default_server;
    server_name aaa.com;
    index index.html index.htm index.php;
    root /data/wwwroot/default;

  location ~ .php$                           ##添加这里
    {
        include fastcgi_params;
        fastcgi_pass unix:/tmp/han.sock;                 
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME /data/wwwroot/default$fastcgi_script_name;
    }

}

php也支持include进入php-fpm.conf下编辑

[[email protected] etc]# mkdir php-fpm.d     ##创建php-fpm.d因为include = etc/php-fpm.d/*.conf!
[[email protected] etc]# cd php-fpm.d/       ##进入
[[email protected] php-fpm.d]# vim www.conf    ##编辑
[www]                                    ##写入一下内容
 listen = /tmp/php-fcgi.sock
#listen = 127.0.0.1:9000
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

[[email protected] php-fpm.d]# vim han.com    ##然后在创建一个目录han.com
[han.com]                       ##写入内容
 listen = /tmp/han.sock
#listen = 127.0.0.1:9000
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

查看配置是否有错

[[email protected] php-fpm.d]# /usr/local/php-fpm/sbin/php-fpm -t
[17-Aug-2018 11:44:58] NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful

*重启效果跟以前没有加include = etc/php-fpm.d/.conf是一样的**

[[email protected] php-fpm.d]# /etc/init.d/php-fpm restart 
Gracefully shutting down php-fpm . done
Starting php-fpm  done

php-fpm慢执行日志

php-fpm的慢执行日志非常有用lamp是没有的，lnmp有，为什么分析慢执行日志，在运维工作当中经常会遇到一个问题，有人经常反馈网站访问慢了，为什么慢要知道根本原因，慢在什么地方，php网站有办法查他到底慢在哪里，用慢执行日志查看

配置php-fpm慢执行日志比如说针对www.conf

编辑/usr/local/php-fpm/etc/php-fpm.d/下的www.conf，添加一下内容

[[email protected] php-fpm.d]# vim /usr/local/php-fpm/etc/php-fpm.d/www.conf      ##加入下边的两行
request_slowlog_timeout = 1
slowlog = /usr/local/php-fpm/var/log/www-slow.log

检测和重新加载

[[email protected] php-fpm.d]# /usr/local/php-fpm/sbin/php-fpm -t
[17-Aug-2018 13:29:11] NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful

[[email protected] php-fpm.d]# /etc/init.d/php-fpm reload
Reload service php-fpm  done

查看有没有生成日志文件如果已生成用cat查看日志

[[email protected] php-fpm.d]# ls /usr/local/php-fpm/var/log/www-slow.log       ##已生成
/usr/local/php-fpm/var/log/www-slow.log

模拟慢执行日志的php写个脚本

[[email protected] php-fpm.d]# vim /data/wwwroot/test.com/sleep.php     编辑个脚本写入下边的代码

<?php echo “test slow log”;sleep(2);echo “done”;?>      ##故意休眠两秒钟
~                                                                                                                                                            
~                                                     

open_basedir

编辑配置文件

[[email protected] php-fpm.d]# vim /usr/local/php-fpm/etc/php-fpm.d/www.conf     ##加入以下配置
php_admin_value[open_basedir]=/data/wwwroot/test.com:/tmp/

启动

测试

查看错误日志

把php-fpm的错误日志定义上

[[email protected] php-fpm.d]# vim /usr/local/php-fpm/etc/php.ini
