Centos7下nginx-1.12.2編輯安裝與腳本安裝的記錄

1、安裝工具及依賴

yum install -y wget make cmake gcc gcc-c++

yum install -y pcre pcre-devel lib zlib-devel  && \

openssl openssl-devel

2、下載及解壓nginx

wget http://nginx.org/download/nginx-1.12.2.tar.gz && \

tar -xzvf  nginx-1.12.2.tar.gz && rm -f nginx-1.12.2.tar.gz && cd nginx-1.12.2
[root@localhost nginx-1.12.2]# pwd
/usr/local/nginx-1.12.2

3、編譯安裝

./configure --prefix=/usr/local/nginx && \
make && make install

四.檢查安裝

啓動Nginx，啓動完以後檢查nginx是否已經正常啓動

[root@localhost nginx-1.12.2]# /usr/local/nginx/sbin/nginx
[root@localhost nginx-1.12.2]# ps -ef |grep nginx
root      12563      1  0 14:44 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx
nobody    12564  12563  0 14:44 ?        00:00:00 nginx: worker process

root      12568   3627  0 14:45 pts/1    00:00:00 grep --color=auto nginx

5、nginx經常使用命令

/usr/local/nginx/sbin/nginx -s start 啓動nginx
/usr/local/nginx/sbin/nginx -s stop 關閉nginx
/usr/local/nginx/sbin/nginx -s reload 重啓nginx

6、配置防火牆

[root@localhost nginx-1.12.2]# firewall-cmd --zone=public --add-port=80/tcp --permanent
success
[root@localhost nginx-1.12.2]# firewall-cmd --reload
success

7、測試nginx訪問

經過瀏覽器訪問nginx歡迎頁，在地址欄輸入：http://192.1680.122，以下圖所示。

8、配置nginx

nginx最重要的配置文件nginx.conf

[root@localhost nginx-1.12.2]# vi /usr/local/nginx/conf/nginx.conf

#user  nobody;

#開啓進程數 <=cpu數
worker_processes  1;

#錯誤日誌保存位置
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#進程號保存文件
#pid        logs/nginx.pid;


#每一個進程最大鏈接數（最大鏈接=鏈接數x進程數）每一個worker容許同時產生多少個連接，默認1024
events {
    worker_connections  1024;
}


http {
	#文件擴展名與文件類型映射表
    include       mime.types;
	 #默認文件類型
    default_type  application/octet-stream;

	#日誌文件輸出格式 這個位置相於全局設置
    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

	#請求日誌保存位置
    #access_log  logs/access.log  main;

	#打開發送文件
    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
	#鏈接超時時間
    keepalive_timeout  65;

    #打開gzip壓縮
	#gzip  on;

    server {
		#監聽端口
        listen       80;
        #監聽域名
		server_name  localhost;

        #charset koi8-r;

        #nginx訪問日誌放在logs/host.access.log下，而且使用main格式（還能夠自定義格式）
		#access_log  logs/host.access.log  main;
		
		#若是沒有location更明確的匹配訪問路徑的話，訪問請求都會被該location處理
        location / {
			#root指定nginx的根目錄爲/usr/local/nginx/html
            root   html;
			 #默認訪問文件，歡迎頁先去html目錄下找index.html，若是找不到再去找index.htm
            index  index.html index.htm;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
		#錯誤頁面及其返回地址，錯誤碼爲500、50二、50三、504都會返回50.html錯誤頁面。
        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 ssl;
    #    server_name  localhost;

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

    #    ssl_session_cache    shared:SSL:1m;
    #    ssl_session_timeout  5m;

    #    ssl_ciphers  HIGH:!aNULL:!MD5;
    #    ssl_prefer_server_ciphers  on;

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

}

配置文件裏能夠添加多個server，server監聽的端口不一樣，能夠根據須要讓nginx代理多個端口，每一個端口指定去作某些事情。

九、腳本安裝

#!/usr/bin/env bash
echo -e '\e[31mInstallation tools and dependencies\e[0m'
yum install -y wget make cmake gcc gcc-c++ && \
pcre-devel lib zlib-devel && \
openssl openssl-devel
if [ $? -eq 0 ];then
    echo -e '\e[32mSuccessful!\e[0m'
else
    echo -e '\e[31mFailed\e[0m'
    exit 0
fi
echo -e '\e[31mInstallation nginx\e[0m'
wget http://nginx.org/download/nginx-1.12.2.tar.gz && \
tar -xzvf  nginx-1.12.2.tar.gz && rm -f nginx-1.12.2.tar.gz && cd nginx-1.12.2 &&\
./configure --prefix=/usr/local/nginx && \
make && make install
if [ $? -eq 0 ];then
    echo -e '\e[32mSuccessful!\e[0m'
else
    echo -e '\e[31mFailed\e[0m'
    exit 0
fi
echo -e '\e[31mStart nginx\e[0m'
/usr/local/nginx/sbin/nginx
echo -e '\e[32mSuccessful!\e[0m'

親測成功！主要防火牆開放80端口！
