LNMP_nginx安装

cd /usr/local/src/
wget http://nginx.org/download/nginx-1.6.2.tar.gz
tar zxvf nginx-1.6.2.tar.gz
cd nginx-1.6.2
./configure --prefix=/usr/local/nginx --with-pcre

./configure --prefix=/usr/local/nginx --user=nobody --group=nobody --with-http_stub_status_module --with-http_ssl_module

make
make install

启动nginx：
/usr/local/nginx/sbin/nginx

错误信息：

错误2：

./configure: error: the HTTP rewrite module requires the PCRE library. You can either disable the module by using --without-http_rewrite_module option, or install the PCRE library into the system, or build the PCRE library statically from the source with

yum install -y pcre-devel openssl openssl-devel这个还不行，

ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.38.tar.gz

./configure

make &&make install

编写nginx启动脚本

vim /etc/init.d/nginx  //加入如下内容
#!/bin/bash
# chkconfig: - 30 21
# description: http service.
# Source Function Library
. /etc/init.d/functions
# Nginx Settings

NGINX_SBIN="/usr/local/nginx/sbin/nginx"
NGINX_CONF="/usr/local/nginx/conf/nginx.conf"
NGINX_PID="/usr/local/nginx/logs/nginx.pid"
RETVAL=0
prog="Nginx"

start() {
      echo -n $"Starting $prog: "
      mkdir -p /dev/shm/nginx_temp
      daemon $NGINX_SBIN -c $NGINX_CONF
      RETVAL=$?
      echo
      return $RETVAL
}

stop() {
      echo -n $"Stopping $prog: "
      killproc -p $NGINX_PID $NGINX_SBIN -TERM
      rm -rf /dev/shm/nginx_temp
      RETVAL=$?
      echo
      return $RETVAL
}

reload(){
      echo -n $"Reloading $prog: "
      killproc -p $NGINX_PID $NGINX_SBIN -HUP
      RETVAL=$?
      echo
      return $RETVAL
}

restart(){
      stop
      start
}

configtest(){
$NGINX_SBIN -c $NGINX_CONF -t
return 0
}

case "$1" in
  start)
      start
      ;;
  stop)
      stop
      ;;
  reload)
      reload
      ;;
  restart)
      restart
      ;;
  configtest)
      configtest
      ;;
  *)
      echo $"Usage: $0 {start|stop|reload|restart|configtest}"
      RETVAL=1
esac
exit $RETVAL

保存后，执行
chmod a+x /etc/init.d/nginx
chkconfig --add nginx
chkconfig nginx on

错误：

/usr/local/nginx/sbin/nginx: error while loading shared libraries: libpcre.so.1:

1、首先确认已经安装好pcre 软件（nginx 依赖该软件）

对于/lib/* 32位系统来说：

#查看lib库

`2`	`# ls /lib/ \|grep pcre`

`3`	`libpcre.so.0`

`4`	`libpcre.so.0.0.1`

5 #添加软连接

`6`	`# ln -s /lib/libpcre.so.0.0.1 /lib/libpcre.so.1`

ps: 也有可能 pcre lib文件在目录：/usr/local/lib/

对于/lib64/* 64位系统来说：

#查看lib库

`2`	`# ls /lib64/ \|grep pcre`

`3`	`libpcre.so.0`

`4`	`libpcre.so.0.0.1`

5 #添加软连接

`6`	`# ln -s /lib64/libpcre.so.0.0.1` `/lib64/libpcre.so.1`

也有可能 pcre lib文件在目录：/usr/local/lib64/。

配置nginx

vim /usr/local/nginx/conf/nginx.conf //清空原来的配置，加入如下内容：

user nobody nobody;
worker_processes 2;
error_log /usr/local/nginx/logs/nginx_error.log crit;
pid /usr/local/nginx/logs/nginx.pid;
worker_rlimit_nofile 51200;
events
{
use epoll;
worker_connections 6000;
}
http

}

mkdir /usr/local/nginx/conf/vhosts

vi jzg.conf

// 加入

server

{
listen 80;
server_name localhost;
index index.html index.htm index.php;
root /data/www;

location ~ \.php$ {
      include fastcgi_params;
      fastcgi_pass unix:/tmp/php-fcgi.sock;
      fastcgi_index index.php;
      fastcgi_param SCRIPT_FILENAME /data/www$fastcgi_script_name;
}
}

/usr/local/nginx/sbin/nginx -t 检查配置文件

重新加载/usr/local/nginx/sbin/nginx -s reload

这里会出现一个错误：

2016/07/16 16:52:02 [crit] 23561#0: *89 connect() tounix:/tmp/php-fcgi.sock failed (2: No such file or directory) while connectingto upstream, client: 103.242.111.113, server: localhost, request: "GET/install/ HTTP/1.1", upstream:"fastcgi://unix:/tmp/php-fcgi.sock:", host: "104.193.95.63"

1.Touch /tmp/php-fcgi.sock

2.Chown nobody:nobody /tmp/php-fcgi.sock (这里要先写文件进去，才能改权限)

3.编辑vi /usr/local/nginx/conf/vhosts/jzq.conf

PHP：

vim /usr/local/php/etc/php-fpm.conf //把之前的内容清空，然后写入如下配置：

[global]
pid = /usr/local/php/var/run/php-fpm.pid
error_log = /usr/local/php/var/log/php-fpm.log
[www]
listen = /tmp/php-fcgi.sock
user = php-fpm
group = php-fpm
listen.owner = nobody //和后面的nginx的一致
listen.group = nobody // 同上
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

重启php-fpm与nginx就可以了,l s-all查看/dev/shm/php-cgi.sock由普通文件变成s开头的unix套接字
