• Nginx安装部署


    Nginx ("engine x") 是一个高性能的 HTTP 和 反向代理 服务器,也是一个 IMAP/POP3/SMTP 代理服务器。 Nginx 是由 Igor Sysoev 为俄罗斯访问量第二的 Rambler.ru 站点开发的,第一个公开版本0.1.0发布于2004年10月4日。其将源代码以类BSD许可证的形式发布,因它的稳定性、丰富的功能集、示例配置文件和低系统资源的消耗而闻名。2011年6月1日,nginx 1.0.4发布。

    一般我们都需要先装pcre, zlib,前者为了重写rewrite,后者为了gzip压缩。

    1.选定源码目录

    选定目录 /usr/local/

    cd /usr/local/

    2.安装PCRE库

    cd /usr/local/

    wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.21.tar.gz 

    tar -zxvf pcre-8.21.tar.gz 

    cd pcre-8.21 

    ./configure

    make

    make install 

    3.安装zlib库

    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.安装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.安装nginx

    Nginx 一般有两个版本,分别是稳定版和开发版,您可以根据您的目的来选择这两个版本的其中一个,下面是把 Nginx 安装到/usr/local/nginx 目录下的详细步骤:

    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-openssl=/usr/local/openssl-1.0.1c  指的是openssl-1.0.1c的源码路径

    --with-pcre=/usr/src/pcre-8.21 指的是pcre-8.21 的源码路径。

    --with-zlib=/usr/src/zlib-1.2.8 指的是zlib-1.2.8 的源码路径。

    6.启动

    确保系统的 80 端口没被其他程序占用,

    /usr/local/nginx/sbin/nginx

    检查是否启动成功:

    netstat -ano|grep 80 有结果输入说明启动成功

    打开浏览器访问此机器的 IP,如果浏览器出现 Welcome to nginx! 则表示 Nginx 已经安装并运行成功。

    7.重启

    /usr/local/nginx/sbin/nginx –s reload

    8.修改配置文件

    cd /usr/local/nginx/conf

    vi nginx.conf

    9.常用配置

    #nginx运行用户和组

    user    www www;   

    #启动进程,通常设置成和cpu的数量相等

    worker_processes  4; 

    #全局错误日志及PID文件

    pid /var/run/nginx.pid;

    error_log  /var/log/nginx/error.log;

    events {

            #epoll是多路复用IO(I/O Multiplexing)中的一种方式,但是仅用于linux2.6以上内核,可以大大提高nginx的性能

    use epoll;

                       #单个后台worker process进程的最大并发链接数

            worker_connections  10240;

    }

    #设定http服务器,利用它的反向代理功能提供负载均衡支持

    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;

    #设定负载均衡的服务器列表

            upstream portals {

                      server 172.16.68.134:8082 max_fails=2 fail_timeout=30s;
