一、準備環境：

1.1 操作系統：centos 6、7

安裝常用軟件

yum install tree telnet dos2unix sysstat lrzsz nc nmap zip unzip -y

1.2 官網下載ngnx源碼包nginx-1.12.2.tar.gz，並隱藏nginx版本號和修改nginx軟件名

下載nginx源碼包nginx-1.12.2.tar.gz，並隱藏nginx版本號和修改nginx軟件名（此步驟省略）。

二、開始安裝nginx

2.1 開始安裝nginx並啟動測試

####################快速安裝nginx#############################
 
mkdir /server/tools -p
mkdir /application
yum install openssl openssl-devel pcre pcre-devel -y
useradd www -s /sbin/nologin -M
cd /server/tools/
rz -y  #上傳優化好隱藏nginx版本號和修改nginx軟件名字為Tengine的模板或者直接下載官網wget http://nginx.org/download/nginx-1.12.2.tar.gz，建議上傳優化好的模板
tar xf nginx-1.12.2.tar.gz
cd nginx-1.12.2
./configure --user=www --group=www --prefix=/application/nginx-1.12.2/ --with-http_stub_status_module --with-http_ssl_module
 
make
make install
ln -s /application/nginx-1.12.2 /application/nginx

檢查語法並啟動nginx

/application/nginx/sbin/nginx -t 
/application/nginx/sbin/nginx
[root@web01 nginx-1.12.2]# ps -ef|grep nginx
root     25150     1  0 16:39 ?        00:00:00 nginx: master process /application/nginx-1.12.2 sbin/nginx
www      25151 25150  0 16:39 ?        00:00:00 nginx: worker process               
root     25164 16972  0 16:41 pts/0    00:00:00 grep nginx

瀏覽器打開web02 IP查看是否可以看到nginx主頁：

http://10.0.0.8/

測試完成後關閉nginx服務。

/application/nginx/sbin/nginx -s stop

2.2 優化nginx配置文件

cd /application/nginx/conf/
cp nginx.conf{,.ori}
egrep -v "^$|#" nginx.conf.default >nginx.conf       #最小化nginx配置

查看默認配置文件

[root@web01 conf]# cat nginx.conf 
worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    server {
        listen       80;
        server_name  localhost;
        location / {
            root   html;
            index  index.html index.htm;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
}

vim nginx.conf把server標簽移除，並在http標簽中加入include extra/www.conf;和include extra/status.conf;

[root@web01 conf]# vim nginx.conf
worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    include    extra/www.conf;
    include    extra/status.conf;
}

增加www.conf目錄及配置文件

[root@web01 conf]# pwd
/application/nginx/conf
[root@web01 conf]# mkdir extra
[root@web01 extra]# vim extra/www.conf      #添加server標簽，www1.etiantian.com用於監控www.etiantian.com是否正常
    server {
        listen       80;
        server_name  www.etiantian.com www1.etiantian.com;
        location / {
            root   html/www;
            index  index.html index.htm;
        }
    }

增加status.conf目錄及配置文件
