php-fpm的pool
http://i2.运维网.com/images/blog/201808/17/53497a259ec27c4774aa6d9dd1f8e768.png

　　它的pool就是它的池子


# cd /usr/local/php-fpm/etc/
# ls
pear.confphp-fpm.confphp-fpm.conf.defaultphp.ini
# cat php-fpm.conf

pid = /usr/local/php-fpm/var/run/php-fpm.pid
error_log = /usr/local/php-fpm/var/log/php-fpm.log

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

http://i2.运维网.com/images/blog/201808/17/3b8f39e9032eecddda332b34d0c76349.png

　　设置多个pool
　　*进入/usr/local/php-fpm/etc/下编辑php-fpm.conf


# cd /usr/local/php-fpm/etc/
# ls
pear.confphp-fpm.confphp-fpm.conf.defaultphp.ini
# vim php-fpm.conf
http://i2.运维网.com/images/blog/201808/17/7bb9a0c86e2e8d7f7ae9bd71ad0518fb.png

　　以上添加完成后查看是否有语法错误


# /usr/local/php-fpm/sbin/php-fpm -t
NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful
　　没有语法错误然后重启


# /etc/init.d/php-fpm reload
Reload service php-fpmdone
　　然后用ps看一下


# ps aux |grep php-fpm
http://i2.运维网.com/images/blog/201808/17/aa4669efda3555cff9cf5142eaaffffc.png

　　怎么用两个pool
　　进入 /usr/local/nginx/conf/vhost/目录下编辑test.com.conf


# cd /usr/local/nginx/conf/vhost/
# ls
aaa.com.confld.confproxy.confssl.conftest.com.conf
# vim test.com.conf

# 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


# ls
aaa.com.confld.confproxy.confssl.conftest.com.conf
# vim aaa.com.conf
# 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

http://i2.运维网.com/images/blog/201808/17/0fea191ddd3e2b88372039db1753c4f9.png
http://i2.运维网.com/images/blog/201808/17/ff815b900e0f210028cfadb263905425.png

# mkdir php-fpm.d   ##创建php-fpm.d因为include = etc/php-fpm.d/*.conf!
# cd php-fpm.d/       ##进入
# vim www.conf    ##编辑
                                    ##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

# vim han.com    ##然后在创建一个目录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


# /usr/local/php-fpm/sbin/php-fpm -t
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**


# /etc/init.d/php-fpm restart
Gracefully shutting down php-fpm . done
Starting php-fpmdone

php-fpm慢执行日志
http://i2.运维网.com/images/blog/201808/17/b029348e488d175a20e297dd1b1fbac4.png
　　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


# 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

http://i2.运维网.com/images/blog/201808/17/7b4423f316edfc686f11cb1d8a19fdb9.png

　　检测和重新加载


# /usr/local/php-fpm/sbin/php-fpm -t
NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful
# /etc/init.d/php-fpm reload
Reload service php-fpmdone

　　查看有没有生成日志文件如果已生成用cat查看日志


# 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


# vim /data/wwwroot/test.com/sleep.php   编辑个脚本写入下边的代码
      ##故意休眠两秒钟
~                                                                                                                                                            
~

open_basedir
http://i2.运维网.com/images/blog/201808/17/b45cc27501f742bd22d738d07be4067d.png

　　编辑配置文件


# vim /usr/local/php-fpm/etc/php-fpm.d/www.conf   ##加入以下配置
php_admin_value=/data/wwwroot/test.com:/tmp/
http://i2.运维网.com/images/blog/201808/17/10ec907d6dc00774a783acf592a9052a.png

　　启动

http://i2.运维网.com/images/blog/201808/17/fae4e2ded397f66bddba30b579f2827c.png

　　测试

http://i2.运维网.com/images/blog/201808/17/3b33d72e5a7b11cb44cb31643d55bc5d.png

　　查看错误日志

　　把php-fpm的错误日志定义上

# vim /usr/local/php-fpm/etc/php.ini
