Nginx 安装
系统平台：CentOS release 6.6 (Final) 64位。
一、安装编译工具及库文件
yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel
二、首先要安装 PCRE
PCRE 作用是让 Nginx 支持 Rewrite 功能。
1、下载 PCRE 安装包，下载地址： http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz
[root@bogon src]# cd /usr/local/src/
[root@bogon src]# wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz
2、解压安装包:
[root@bogon src]# tar zxvf pcre-8.35.tar.gz
3、进入安装包目录
[root@bogon src]# cd pcre-8.35
4、编译安装
[root@bogon pcre-8.35]# ./configure
[root@bogon pcre-8.35]# make && make install
5、查看pcre版本
[root@bogon pcre-8.35]# pcre-config --version
安装 Nginx
1、下载 Nginx，下载地址：https://nginx.org/en/download.html
[root@bogon src]# cd /usr/local/src/
[root@bogon src]# wget http://nginx.org/download/nginx-1.6.2.tar.gz
2、解压安装包
[root@bogon src]# tar zxvf nginx-1.6.2.tar.gz
3、进入安装包目录
[root@bogon src]# cd nginx-1.6.2
4、编译安装
[root@bogon nginx-1.6.2]# ./configure --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.35
[root@bogon nginx-1.6.2]# make && make install
5、查看nginx版本
[root@bogon nginx-1.6.2]# /usr/local/webserver/nginx/sbin/nginx -v
到此，nginx安装完成。
Nginx 配置
创建 Nginx 运行使用的用户 www：
[root@bogon conf]# /usr/sbin/groupadd www
[root@bogon conf]# /usr/sbin/useradd -g www www
配置nginx.conf ，将/usr/local/webserver/nginx/conf/nginx.conf替换为以下内容
[root@bogon conf]# cat /usr/local/webserver/nginx/conf/nginx.conf
user www www;
worker_processes 2; #设置值和CPU核心数一致
error_log /usr/local/webserver/nginx/logs/nginx_error.log crit; #日志位置和日志级别
pid /usr/local/webserver/nginx/nginx.pid;#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 65535;
events{
use epoll;
worker_connections 65535;}
http{
include mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" $http_x_forwarded_for';
#charset gb2312;
server_names_hash_bucket_size 128;
client_header_buffer_size 32k;
large_client_header_buffers 4 32k;
client_max_body_size 8m;
sendfile on;
tcp_nopush on;
keepalive_timeout 60;
tcp_nodelay on;
fastcgi_connect_timeout 300;

#limit_zone crawler $binary_remote_addr 10m;
#下面是server虚拟主机的配置
server
{
listen 80;#监听端口
server_name localhost;#域名
index index.html index.htm index.php;
root /usr/local/webserver/nginx/html;#站点目录
location ~ .*.(php|php5)?$
{
#fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
location ~ .*.(gif|jpg|jpeg|png|bmp|swf|ico)$
{

# access_log off;
}
location ~ .*.(js|css)?$
{

# access_log off;
}
access_log off;
}
}
检查配置文件nginx.conf的正确性命令：
[root@bogon conf]# /usr/local/webserver/nginx/sbin/nginx -t
启动 Nginx
Nginx 启动命令如下：
[root@bogon conf]# /usr/local/webserver/nginx/sbin/nginx
访问站点
从浏览器访问配置的站点ip：
Nginx 其他命令
以下包含了 Nginx 常用的几个命令：
/usr/local/webserver/nginx/sbin/nginx -s reload # 重新载入配置文件
/usr/local/webserver/nginx/sbin/nginx -s reopen # 重启
Nginx/usr/local/webserver/nginx/sbin/nginx -s stop # 停止 Nginx
安装后的优化
11.编写nginx服务脚本
vim /etc/init.d/nginx
将内容全部替换：
#!/bin/bash
# chkconfig: 2345 99 20
# description: Nginx Server Control Script
PROG="/usr/local/nginx/sbin/nginx"
PIDF="/usr/local/nginx/logs/nginx.pid"
case "$1" in
start)
$PROG
;;
stop)
kill -s QUIT $(cat $PIDF)
;;
restart)
$0 stop
$0 start
;;
reload)
kill -s HUP $(cat $PIDF)
;;
*)
echo "Usage: $0 {start|stop|restart|reload}"
exit 1
esac
exit 0
12.给该文件添加执行权限
chmod +x /etc/init.d/nginx
13.通过脚本可以启动、停止、重启、重载服务器
chkconfig --add nginx
chkconfig nginx on
chkconfig --list nginx
14.配置nginx.conf文件
vim /usr/local/nginx/conf/nginx.conf
将内容全部替换：
user nginx nginx;
worker_processes 2;
worker_cpu_affinity 01 10;
worker_rlimit_nofile 102400;
error_log logs/error.log;
pid logs/nginx.pid;
events {
use epoll;
worker_connections 4096;
}
http {
include mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log logs/access.log main;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name localhost;
charset utf-8;
location / {
root html;
index index.html index.htm;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}
15.修改nginx.conf主配置文件
vim /usr/local/nginx/conf/nginx.conf 添加内容：（第一个location下）
location /status {
stub_status on;
access_log off;
}
实现访问IP地址下的ststus可以显示nginx界面
16.重启服务
systemctl restart nginx
**若已经安装nginx，要隐藏版本号
vim /usr/local/nginx/conf/nginx.conf
添加内容：
server_tokens off;
重启服务
/usr/local/nginx/sbin/nginx -t
Killall -1 nginx
测试：IP地址/任意字符
