nginx安装部署

1 编译环境

nginx可以使用各平台的默认包来安装，本文是介绍使用源码编译安装，包括具体的编译参数信息。

正式开始前，编译环境gcc g++ 开发库之类的需要提前装好，这里默认你已经装好。

ububtu平台编译环境可以使用以下指令

apt-get install build-essential

apt-get install libtool

centos平台编译环境使用如下指令

安装make：

yum -y install gcc automake autoconf libtool make

安装g++:

yum install gcc gcc-c++

.2选定源码目录

可以是任何目录，本文选定的是/usr/local/src

cd /usr/local/src

5.3安装PCRE库

1）下载最新的 PCRE 源码包，使用下面命令下载编译和安装 PCRE 包：

2）cd /usr/local/src

3）wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.34.tar.gz

4）tar -zxvf pcre-8.34.tar.gz

5）cd pcre-8.34

6）./configure

7）make

8）make install

.4安装zlib库

1）http://zlib.net/zlib-1.2.8.tar.gz 下载最新的 zlib 源码包，使用下面命令下载编译和安装 zlib包：

2）cd /usr/local/src

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

4）tar -zxvf zlib-1.2.8.tar.gz

5）cd zlib-1.2.8

6）./configure

7）make

8）make install

5 安装ssl（某些vps默认没装ssl)

cd /usr/local/src

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

tar -zxvf openssl-1.0.1c.tar.gz

56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/src

wget http://nginx.org/download/nginx-1.4.2.tar.gz

tar -zxvf nginx-1.4.2.tar.gz

cd nginx-1.4.2

./configure --sbin-path=/usr/local/nginx/nginx \

--conf-path=/usr/local/nginx/nginx.conf \

--pid-path=/usr/local/nginx/nginx.pid \

--with-http_ssl_module \

--with-pcre=/usr/local/src/pcre-8.34 \

--with-zlib=/usr/local/src/zlib-1.2.8 \

--with-openssl=/usr/local/src/openssl-1.0.1c

make

make install

--with-pcre=/usr/src/pcre-8.34 指的是pcre-8.34 的源码路径。

--with-zlib=/usr/src/zlib-1.2.7 指的是zlib-1.2.7 的源码路径。

安装成功后 /usr/local/nginx 目录下如下

fastcgi.conf            koi-win             nginx.conf.default

fastcgi.conf.default    logs                scgi_params

fastcgi_params          mime.types          scgi_params.default

fastcgi_params.default  mime.types.default  uwsgi_params

html                    nginx               uwsgi_params.default

koi-utf                 nginx.conf          win-utf

5.6启动

1）确保系统的 80 端口没被其他程序占用，运行/usr/local/nginx/nginx 命令来启动 Nginx

netstat -ano|grep 80
修改/usr/local/nginx/conf/nginx.conf


#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


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;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;
    ## 此处添加要关联的tomcat地址:端口 redis3是本机的hostaneme
    upstream redis3 {
        server 192.168.10.125:8080;
        server 192.168.10.126:8080;
    }
    server {
        listen       80;
        server_name  redis3;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;
        location / {
            root   html;  
            index  index.html index.htm;  
            proxy_pass        http://redis3;  ##此处redis是本机的
            hostnameproxy_set_header  X-Real-IP  $remote_addr;
            client_max_body_size  100m;
        }  

        #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;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        #location ~ \.php$ {
        #    proxy_pass   http://127.0.0.1;
        #}

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        #location ~ \.php$ {
        #    root           html;
        #    fastcgi_pass   127.0.0.1:9000;
        #    fastcgi_index  index.php;
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        #    include        fastcgi_params;
        #}

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }


    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}


    # HTTPS server
    #
    #server {
    #    listen       443;
    #    server_name  localhost;

    #    ssl                  on;
    #    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;

    #    ssl_session_timeout  5m;

    #    ssl_protocols  SSLv2 SSLv3 TLSv1;
    #    ssl_ciphers  HIGH:!aNULL:!MD5;
    #    ssl_prefer_server_ciphers   on;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

}

然后启动nginx 访问如果出现tomcat的访问页代表配置ok
