ginx 安装配置
系统平台：CentOS release 6.6 (Final) 64位。
一、安装编译工具及库文件
```bash
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。
```bash
[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：
```bash
[root@bogon src]# tar zxvf pcre-8.35.tar.gz
```
3、进入安装包目录
```bash
[root@bogon src]# cd pcre-8.35
```
4、编译安装
```bash
[root@bogon pcre-8.35]# ./configure [root@bogon pcre-8.35]# make && make install
```
5、查看pcre版本
```bash
[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
```bash
[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
```bash
[root@bogon src]# tar zxvf nginx-1.6.2.tar.gz
```
3、进入安装包目录
```bash
[root@bogon src]# cd nginx-1.6.2
```
4、编译安装
以下是nginx的安装和配置过程：
1. 下载并解压nginx:
```bash
[root@ Bogon nginx-1.6.2]# wget http://nginx.org/download/nginx-1.6.2.tar.gz
[root@ Bogon nginx-1.6.2]# tar -zxvf nginx-1.6.2.tar.gz
[root@ Bogon nginx-1.6.2]# cd nginx-1.6.2
```
2. 配置nginx,指定安装目录、启用http_stub_status_module、http_ssl_module模块以及使用pcre库(版本为8.35):
```bash
[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
```
3. 编译并安装nginx:
```bash
[root@ Bogon nginx-1.6.2]# make
[root@ Bogon nginx-1.6.2]# make install
```
4. 查看nginx版本：
```bash
[root@ Bogon nginx-1.6.2]# /usr/local/webserver/nginx/sbin/nginx -v
```
至此，nginx安装完成。接下来进行Nginx配置。首先创建一个运行使用的用户www:
```bash
[root@ Bogon conf]# /usr/sbin/groupadd www
[root@ Bogon conf]# /usr/sbin/useradd -g www www
```
以下是重构后的nginx配置文件：
```
[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"

} #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相关配置，如有需要可以注释掉或删除这部分内容。fastcgi_pass unix:/tmp/php-cgi.sock;fastcgi_pass 127.0.0.1:9000;fastcgi_index index.php;include fastcgi.conf;} #end of location ~* \.(php|php5)?$ block #end of server {' #end of server block #access log off #} #end of http {} #end of server {} #end of events {} #end of http {} #end of configuration #} #end of file #
检查配置文件nginx.conf的正确性，可以使用以下命令：
```
[root@bogon conf]# /usr/local/webserver/nginx/sbin/nginx -t
```
启动 Nginx,可以使用以下命令：
```
[root@bogon conf]# /usr/local/webserver/nginx/sbin/nginx
```
访问站点时，可以从浏览器输入配置的站点IP进行访问。
Nginx 还有其他常用命令，包括：
- 重新载入配置文件：`/usr/local/webserver/nginx/sbin/nginx -s reload`
- 重启 Nginx:`/usr/local/webserver/nginx/sbin/nginx -s reopen`
- 停止 Nginx:`/usr/local/webserver/nginx/sbin/nginx -s stop`
