vim /etc/profile
PATH=$PATH:/soft/jdk/bin:/soft/jdk/jre/bin:/soft/nginx/sbin:/soft/php/bin:/soft/php/sbin
source /etc/profile
 php -v
 
groupadd www
useradd php-fpm -M -s /sbin/nologin -g www

vim /soft/php/etc/php-fpm.conf
/*配置一下*/
; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
;       will be used.
user = php-fpm
group = www
/*配置完毕*/
php-fpm -v

netstat -ltunp | grep 9000

nginx -s reload

/*PHP想关*/
chmod -R 777 /x4f_oa/www
php --ini

解决java验证码文字问题

yum groupinstall "Fonts"
/soft/tomcat/bin/catalina.sh stop
/soft/tomcat/bin/catalina.sh start

linux 命令行，ctrl+c退出当前命令

php-fpm的重启方法

启动方法 直接 **php-fpm**

php-fpm master 进程可以理解一下以下的信号：

INT, TERM 立刻终止

QUIT 平滑终止

USR1 重新打开日志文件

USR2 平滑重载所有worker进程并重新载入配置和二进制模块

首先查看php-fpm 进程

ps -aux | grep php

优雅的重启php-fpm:

kill -USR2 14742

OK了。

上面方案一般是没有生成php-fpm.pid文件时使用，如果要生成php-fpm.pid，使用下面这种方案：

上面master进程可以看到，matster使用的是/usr/local/php/etc/php-fpm.conf这个配置文件，cat /usr/local/php/etc/php-fpm.conf 发现：

[global]
; Pid file
; Note: the default prefix is /usr/local/php/var
; Default Value: none
;pid = run/php-fpm.pid

pid文件路径应该位于/usr/local/php/var/run/php-fpm.pid，由于注释掉，所以没有生成，我们把注释去除，再kill -USR2 42891 重启php-fpm,便会生成pid文件，下次就可以使用以下命令重启,关闭php-fpm了：

php-fpm 关闭：
kill -INT 'cat /usr/local/php/var/run/php-fpm.pid'
php-fpm 重启：
kill -USR2 'cat /usr/local/php/var/run/php-fpm.pid'
nginx重启：进入nginx可执行目录sbin下，输入命令**./nginx -s reload **即可。
php-fpm重启：killall php-fpm && /usr/local/php/sbin/php-fpm

我的主机的php-fpm.pid

[global]
; Pid file
; Note: the default prefix is /soft/php/var
; Default Value: none
pid = run/php-fpm.pid
/soft/php/var/run/php-fpm.pid

tomcat启动后访问非常慢 random改为urandom

原因是session计算的问题可以看CSDN的文章
文件在java安装目录/soft/jdk/jre/lib/security/java.security

# In addition, if "file:/dev/random" or "file:/dev/urandom" is
# specified, the "NativePRNG" implementation will be more preferred than
# SHA1PRNG in the Sun provider.
