一、安裝

1、下載（此處不再贅述，忽略）

2、解壓到指定目錄

[root@localhost home]# tar zxvf nginx-1.11.2.tar.gz -C /myapp/

[root@localhost home]# cd /myapp/nginx-1.11.2/

[root@localhost nginx-1.11.2]# ls

auto CHANGES CHANGES.ru conf configure contrib html LICENSE man README src

3、使用yum安裝依賴庫(kù) 【gcc 、pcre、openssl、zilib】

[root@localhost nginx-1.11.2]# yum -y install gcc

[root@localhost nginx-1.11.2]# yum -y install pcre

[root@localhost nginx-1.11.2]# yum -y install openssl

[root@localhost nginx-1.11.2]# yum -y install zlib

4、編譯并安裝

[root@localhost nginx-1.11.2]# ./configure –prefix=/usr/local/nginx –with-http_stub_status_module

[root@localhost nginx-1.11.2]# make

[root@localhost nginx-1.11.2]# make install

5、說(shuō)明：

參數(shù) –with-http_stub_status_modul是為了啟用nginx的 NginxStatus 功能，用來(lái)監(jiān)控 Nginx 的當(dāng)前狀態(tài)

–prefix=/usr/local/nginx 指定安裝目錄更詳細(xì)的參數(shù)參考./configure –help

安裝成功后 /usr/local/nginx 目錄下有四個(gè)子目錄分別是：conf、html、logs、sbin 。

二、配置Nginx

1、配置

user root root; #工作進(jìn)程的屬主

worker_processes 1; #工作進(jìn)程數(shù)，一般與 CPU核數(shù)等同

#error_log logs/error.log;

#error_log logs/error.log notice;

#error_log logs/error.log info;

#pid logs/nginx.pid;

2、測(cè)試

測(cè)試配置文件是否正確

[root@localhost conf]# /usr/local/nginx/sbin/nginx -t

如果顯示以下信息，說(shuō)明配置正確可以啟動(dòng)Nginx服務(wù)

nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok

nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

3、啟動(dòng)、重啟、停止、重新加載配置文件命令

啟 動(dòng)nginx： /usr/local/nginx/sbin/nginx

重 啟Nginx： /usr/local/nginx/sbin/nginx -s reload

停 止Nginx：/usr/local/webserver/nginx/sbin/nginx -s stop

重新加載配置文件：/usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf
