Linux安装Nginx-1.1.10

Nginx（发音同engine x）是一个异步框架的 Web服务器，也可以用作反向代理，负载平衡器和 HTTP缓存。相较于Apache\lighttpd具有占有内存少，稳定性高等优势，并且依靠并发能力强，丰富的模块库以及友好灵活的配置而闻名。在Linux操作系统下，nginx使用epoll事件模型,得益于此，nginx在Linux操作系统下效率相当高。

开始前，请确认gcc g++开发类库是否装好，默认已经安装，安装步骤：

gcc安装

yum -y install gcc-c++

pcre安装

yum -y install  pcre pcre-devel

zlib安装

yum -y install zlib zlib-devel

OpenSSL安装

yum -y install openssl openssl-devel

Nginx安装

cd /usr/local/src
wget http://nginx.org/download/nginx-1.1.10.tar.gz
tar -zxvf nginx-1.1.10.tar.gz
cd nginx-1.1.10
./configure
make
make install

启动Nginx

为了防止端口80占用，apache端口尽量不要修改，所有我们可以选择修改Nginx端口，linux配置文件路径：/usr/local/nginx/conf/nginx.conf，可以修改端口为8888，当然也可以保留原始的80端口，我这里暂时不做修改。

下面是nginx.conf原始配置文件：


#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;

    server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

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

        #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;
    #    }
    #}

}

启动nginx

netstat -ano|grep 80

nginx重启、关闭、启动

启动

启动代码格式：nginx安装目录地址 -c nginx配置文件地址

例如：

[root@iz2zeg4xqcv95kl86o2w9bz /]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

如果你启动时遇到：

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

由于nginx默认启动的是80端口，而80端口服务器上其他应用占用，解决办法：可以使用

sudo fuser -k 80/tcp  #关闭所有80端口的程序

使用效果如下：

[root@iz2zeg4xqcv95kl86o2w9bz /]# sudo fuser -k 80/tcp
80/tcp: 21290 25925 25928 25929 25930 25931 25932

再次启动，启动成功！

停止

1.查看Nginx进程号

[root@iz2zeg4xqcv95kl86o2w9bz ~]# ps -ef|grep nginx

2.杀死进程

[root@iz2zeg4xqcv95kl86o2w9bz ~]# kill -QUIT 进程ID

重启

第一步，验证nginx配置文件是否正确：

方法一：进入nginx安装目录sbin下，输入命令 ./nginx -t

看到如下显示nginx.conf syntax ok ，nginx.conf test is successful，说明配置文件正确！

方法二：在启动命令-c前加-t

 /usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf

第二步，重启nginx

进入nginx可执行目录sbin下，输入命令 ./nginx -s reload 即可重启

最终结果：

项目文件存放路径 : /usr/local/nginx/html
