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/www.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

实例：

在/usr/local/php/etc/php-fpm.conf中添加test.com

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        #日志记录的时候1秒

slowlog = /usr/local/php-fpm/var/log/www-slow.log           #日志记录的位置

• 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

cat /usr/local/php-fpm/var/log/www-slow.log                 #显示为空，因为没有执行php

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

[root@localhost ]# vi test.com.conf把unix:/tmp/php-fcgi.sock改为unix:/tmp/www.sock

设置慢执行日志

[root@localhost php-fpm.d]# vim /data/wwwroot/test.com/sleep.php           #编写一个休眠2秒的php文件
<?phpecho “test slow log”;
sleep(2);
echo “done”;
?>[root@localhost php-fpm.d]# curl -x 127.0.0.1:80 test.com/sleep.php
[root@localhost php-fpm.d]# curl -x 127.0.0.1:80 test.com/sleep.php -I       、#-I检测有没有语法错误

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/

v  

• 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

实例：

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

[root@localhost php-fpm.d]# vi www.conf//加入如下内容
[www]
#listen = /tmp/php-fcgi.sock

pm.max_requests = 500
rlimit_files = 1024

[root@localhost php-fpm.d]# /etc/init.d/php-fpm restart[root@localhost php-fpm.d]# ls

查看错误日志

[root@localhost php-fpm.d]#vi /usr/local/php-fpm/etc/php.ini
/display_error      //搜索的内容
/display_errors = Off        //修改成原来的off/error_log       //搜索的内容,,,在error_log = syslog下面添加
error_log = /usr/local/php-fpm/var/log/php_errors.log/error_reporting         //搜索的内容在;error_reporting = E_ALL & -E_DEPRECATED & -E_STRICT下面添加然后 把添加的哪一行上面的一行注释掉。
error_reporting = E_ALL[root@localhost php-fpm.d]# grep error_log /usr/local/php-fpm/etc/php.ini    #查看错误日志
error_log = /usr/local/php-fpm/var/log/php_errors.logroot@localhost php-fpm.d]# touch /usr/local/php-fpm/var/log/php_errors.log手动生成一个错误日志
root@localhost php-fpm.d]# chmod 777 /usr/local/php-fpm/var/log/php_errors.log
root@localhost php-fpm.d]#/etc/init.d/php-fpm restart      #重启一下
root@localhost php-fpm.d]# curl -x 127.0.0.1:80 test.com/3.php -I   #重新访问root@localhost php-fpm.d]# cat /usr/local/php-fpm/var/log/php_errors.log       #查看错误日志 

注意：open_basedir 的作用是限制php在指定的目录里活动。

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

注意：注释的时候用；号

• 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。

空闲意思是，没有访问的时候。

• 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。
