12.21 php-fpm的pool

vim /usr/local/php/etc/php-fpm.conf //在[global]部分增加

include = etc/php-fpm.d/*.conf

mkdir /usr/local/php/etc/php-fpm.d/
cd /usr/local/php/etc/php-fpm.d/

vim www.conf //内容如下
[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

继续编辑配置文件
vim aming.conf //内容如下
[aming]
listen = /tmp/aming.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/sbin/php-fpm –t
/etc/init.d/php-fpm restart

[root@linux-01 aming.com]# cd /usr/local/php-fpm/etc/
[root@linux-01 etc]# ls
pear.conf  php-fpm.conf  php-fpm.conf.default  php.ini

[root@linux-01 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.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

[root@linux-01 etc]# vim php-fpm.conf
添加一下内容

[aming.com]
listen = /tmp/aming.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

[root@linux-01 etc]# /usr/local/php-fpm/sbin/php-fpm -t

[root@linux-01 etc]# ps aux | grep -i php-fpm     //多了一个aming.com

[root@linux-01 etc]# cd /usr/local/nginx/conf/vhost/
[root@linux-01 vhost]# ls
aaa.com.conf  load.conf  proxy.conf  ssl.conf  test.com.conf

[root@linux-01 vhost]# vi aaa.com.conf 
//添加location php部分
server

    listen 80 default_server;
    server_name aaa.com;
    index index.html index.htm index.php;
    root /data/wwwroot/default;
    location ~ \.php$

        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME /data/wwwroot/default$fastcgi_script_name;
    }
}

多个pool,有的网址无法访问时，别的网页不受影响

[root@linux-01 ~]# cd /usr/local/php-fpm/etc/
[root@linux-01 etc]# ls
pear.conf  php-fpm.conf  php-fpm.conf.default  php.ini

[root@linux-01 etc]# vim php-fpm.conf
//改为如下内容

[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

[root@linux-01 etc]# mkdir php-fpm.d
[root@linux-01 etc]# cd php-fpm.d/

[root@linux-01 php-fpm.d]# vim aming.conf
[aming.com]
listen = /tmp/aming.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

[root@linux-01 php-fpm.d]# 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

[root@linux-01 php-fpm.d]# /usr/local/php-fpm/sbin/php-fpm -t

配置成多个pool 池子后，和原来的一个php-fpm.conf配置多个pool效果一样

12.22 php-fpm慢执行日志

vim /usr/local/php-fpm/etc/php-fpm.d/www.conf //加入如下内容
request_slowlog_timeout = 1
slowlog = /usr/local/php-fpm/var/log/www-slow.log

配置nginx的虚拟主机test.com.conf，把unix:/tmp/php-fcgi.sock改为unix:/tmp/www.sock

重新加载nginx服务

vim /data/wwwroot/test.com/sleep.php //写入如下内容
<?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

操作过程

[root@linux-01 php-fpm.d]# vim www.conf 
//添加如下内容
request_slowlog_timeout = 1
slowlog = /usr/local/php-fpm/var/log/www-slow.log

[root@linux-01 php-fpm.d]# /usr/local/php-fpm/sbin/php-fpm -t
[29-Mar-2018 07:08:29] NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful

[root@linux-01 php-fpm.d]# /etc/init.d/php-fpm reload

[root@linux-01 php-fpm.d]# vim /data/wwwroot/test.com/sleep.php
<?php
echo "test slow log";
sleep(2);
echo "done";
?>

[root@linux-01 php-fpm.d]# curl -x127.0.0.1:80 test.com/sleep.php
停顿2秒

[root@linux-01 php-fpm.d]# cat /usr/local/php-fpm/var/log/www-slow.log

12.23 open_basedir

vim /usr/local/php-fpm/etc/php-fpm.d/aming.conf //加入如下内容

php_admin_value[open_basedir]=/data/wwwroot/aming.com:/tmp/

创建测试php脚本，进行测试
再次更改aming.conf，修改路径，再次测试
配置错误日志
再次测试
查看错误日志

php-fcgi.sock

操作过程

[root@linux-01 php-fpm.d]# vim www.conf    //添加一下内容
php_admin_value[open_basedir]=/data/wwwroot/test.com:/tmp/

[root@linux-01 php-fpm.d]# /usr/local/php-fpm/sbin/php-fpm -t
[29-Mar-2018 08:32:55] NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful

12.24 php-fpm进程管理

pm = dynamic //动态进程管理，也可以是static
pm.max_children = 50 //最大子进程数，ps aux可以查看
pm.start_servers = 20 //启动服务时会启动的进程数
pm.min_spare_servers = 5 //定义在空闲时段，子进程数的最少数量，如果达到这个数值时，php-fpm服务会自动派生新的子进程。
pm.max_spare_servers = 35 //定义在空闲时段，子进程数的最大值，如果高于这个数值就开始清理空闲的子进程。
pm.max_requests = 500 //定义一个子进程最多处理的请求数，也就是说在一个php-fpm的子进程最多可以处理这么多请求，当达到这个数值时，它会自动退出。
