nginx用起来很顺手啊,没有什么不正常的啊,xooass是DZ的吧,这个大的进程数需要相当大的内存的哦!
现在的客户新买机器的内存基本都在16G-32G，然后数据库也是另外的独立服务器，开1024个不是问题。
在资源足够的情况下，开大点可以杜绝偶然出现的502，何乐不为呢? 尽量不出问题客户才能安心，而不是介意要买多少内存 今天spawn-fcgi升级了
你们升了再看看呢 原帖由 kisswen 于 2009-11-18 15:51 发表 http://bbs3.chinaunix.net/images/common/back.gif
今天spawn-fcgi升级了
你们升了再看看呢
十分感谢，我看看。
故障依旧，不能解决。
spawn-fcgi 的php-cgi常常崩溃退出 nginx用起来很顺手啊,没有什么不正常的啊,xooass是DZ的吧,这个大的进程数需要相当大的内存的哦!ylshjx 发表于 2009-11-17 09:02 http://bbs.chinaunix.net/images/common/back.gif
我使用i386的服务器也没有任何问题。 基于CentOS 5.4搭建nginx+php+spawn-fcgi+mysql高性能php平台

2.5安装Zend
CODE:
#tar zvxf ZendOptimizer-3.3.3-linux-glibc23-x86_64.tar.gz
# cd ZendOptimizer-3.3.3-linux-glibc23-x86_64
# ./install
注：php.ini的位置为/usr/local/php/etc 服务器不选用apache
三、配置整合
3.1 配置nginx
注：本文spawn-fcgi开启9000跟9001两个端口，利用nginx的upstream负载均衡php程序到不同的fcgi端口上面，解决502 gateway错误
#cd /usr/local/nginx/conf
#cp nginx.conf nginx.conf.linuxtone
#vi nginx.conf
CODE:
userwww www;
worker_processes 10;
pid /var/run/nginx.pid;

#Specifies the value for maximum file descriptors that can be opened by this process.

3.2 配置spawn-fcgi启动脚本
#mkdir /usr/local/php/sbin
# vi /usr/local/php/sbin/spawn-fcgi
CODE:
#! /bin/sh
set -e
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
DESC="spawn-fcgi daemon"
NAME=spawn-fcgi
DAEMON=/usr/local/bin/$NAME
# Gracefully exit if the package has been removed.
test -x $DAEMON || exit 0
d_start() {
$DAEMON -a 127.0.0.1 -p 9000 -C 128 -u www -g www -f /usr/local/php/bin/php-cgi > /dev/null 2>&1
$DAEMON -a 127.0.0.1 -p 9001 -C 128 -u www -g www -f /usr/local/php/bin/php-cgi > /dev/null 2>&1 || echo -n " already running"
}
d_stop() {
/usr/bin/killall -9 php-cgi > /dev/null 2>&1 || echo -n " not running"
}
case "$1" in
start)
echo -n "Starting $DESC: $NAME"
d_start
echo "."
;;
stop)
echo -n "Stopping $DESC: $NAME"
d_stop
echo "."
;;
restart)
echo -n "Restarting $DESC: $NAME"
d_stop
sleep 1
d_start
echo "."
;;
*)
echo "Usage: $SCRIPTNAME {start|stop|restart}" >&2
exit 3
;;
esac
exit 0
#chmod 755 /usr/local/php/sbin/spawn-fcgi
四、启动WEB服务
4.1.启动spawn-fcgi
#/usr/local/php/sbin/spawn-fcgi start
4.2.启动nginx
4.2.1检查nginx配置：
# /usr/local/nginx/sbin/nginx –t //返回如下信息说明配置正确
CODE:
the configuration file /usr/local/nginx//conf/nginx.conf syntax is ok
configuration file /usr/local/nginx//conf/nginx.conf test is successful
#/usr/local/nginx/sbin/nginx //启动nginx
4.3.加入开机启动
#vi /etc/rc.local
在最后加入：
CODE:
ulimit -SHn 51200
/usr/local/nginx/sbin/nginx
/usr/local/php/sbin/spawn-fcgi start
五、测试
#mkdir /data/www/wwwroot/linuxtone
#vi phpinfo.php 我用FreeBSD7.2经常出现502。不知道为什么。请加我53252734
