nignx安裝

Nginx安裝部署

Nginx ("engine x") 是一個高性能的 HTTP 和 反向代理 服務器，也是一個 IMAP/POP3/SMTP 代理服務器。 Nginx 是由 Igor Sysoev 爲俄羅斯訪問量第二的 Rambler.ru 站點開發的，第一個公開版本0.1.0發佈於2004年10月4日。其將源代碼以類BSD許可證的形式發佈，因它的穩定性、豐富的功能集、示例配置文件和低系統資源的消耗而聞名。2011年6月1日，nginx 1.0.4發佈。

 

 

 

通常咱們都須要先裝pcre, zlib，前者爲了重寫rewrite，後者爲了gzip壓縮。

1.選定源碼目錄

選定目錄 /usr/local/

 

cd /usr/local/

 

2.安裝PCRE庫

cd /usr/local/

wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.35.tar.gz

tar -zxvf pcre-8.35.tar.gz

cd pcre-8.35

./configure

make

make install

 

3.安裝zlib庫

cd /usr/local/ 

wget http://zlib.net/zlib-1.2.8.tar.gz

tar -zxvf zlib-1.2.8.tar.gz cd zlib-1.2.8

./configure

make

make install

 

4.安裝ssl

 

cd /usr/local/

wget http://www.openssl.org/source/openssl-1.0.1c.tar.gz

tar -zxvf openssl-1.0.1c.tar.gz

./config

make

make install

 

5.安裝nginx

 

Nginx 通常有兩個版本，分別是穩定版和開發版，您能夠根據您的目的來選擇這兩個版本的其中一個，下面是把 Nginx 安裝到 /usr/local/nginx 目錄下的詳細步驟：

 

cd /usr/local/

wget http://nginx.org/download/nginx-1.2.8.tar.gz

tar -zxvf nginx-1.2.8.tar.gz

cd nginx-1.2.8  

./configure --prefix=/usr/local/nginx 

make

make install

 

--with-pcre=/usr/src/pcre-8.21 指的是pcre-8.21 的源碼路徑。

--with-zlib=/usr/src/zlib-1.2.7 指的是zlib-1.2.7 的源碼路徑。

 

6.啓動

確保系統的 80 端口沒被其餘程序佔用，

/usr/local/nginx/sbin/nginx

 

檢查是否啓動成功：

netstat -ano|grep 80 有結果輸入說明啓動成功

 

 

打開瀏覽器訪問此機器的 IP，若是瀏覽器出現 Welcome to nginx! 則表示 Nginx 已經安裝並運行成功。

 

7.重啓

/usr/local/nginx/sbin/nginx –s reload

 

8.修改配置文件

cd /usr/local/nginx/conf

vi nginx.conf

 

9.經常使用配置

#nginx運行用戶和組

user    www www;  

#啓動進程,一般設置成和cpu的數量相等

worker_processes  4;

 

#全局錯誤日誌及PID文件

pid /var/run/nginx.pid;

error_log  /var/log/nginx/error.log;

 

events {

        #epoll是多路複用IO(I/O Multiplexing)中的一種方式,可是僅用於linux2.6以上內核,能夠大大提升nginx的性能

use epoll;

                   #單個後臺worker process進程的最大併發連接數

        worker_connections  10240;

}

#設定http服務器，利用它的反向代理功能提供負載均衡支持

http {

        include       mime.types;

 

        default_type  application/octet-stream;

 

         error_page 400 403 500 502 503 504  /50x.html;

 

        index index.html index.shtml

 

        autoindex off;

 

         fastcgi_intercept_errors on;

 

        sendfile        on;

 

        # These are good default values.

        tcp_nopush      on;

        tcp_nodelay     off;

 

        # output compression saves bandwidth

        gzip  off;

         #gzip_static on;

        #gzip_min_length  1k;

        gzip_http_version 1.0;

        gzip_comp_level 2;

        gzip_buffers  4 16k;

        gzip_proxied any;

        gzip_disable "MSIE [1-6]\.";

        gzip_types  text/plain text/html text/css application/x-javascript application/xml application/xml+rss text/javascript;

        #gzip_vary on;

 

        server_name_in_redirect off;
