linux安裝nginx以及nginx部署前端服務

之前沒在linux上安裝nginx並且部署前端環境，現總結如下

1.下載並解壓壓縮包

cd /app/
//下載tar包
wget http://nginx.org/download/nginx-1.13.7.tar.gz
//解壓tar包
tar -xvf nginx-1.13.7.tar.gz

//我直接解壓，改了名字。即/app/nginx

2.安裝nginx

//進入目錄
cd nginx
//執行命令
./configure
//執行make命令
make
//執行make install命令
make install

3.檢查安裝

# cd到剛才配置的安裝目錄
cd  /app/nginx/

./sbin/nginx -t

正常情況的信息輸出：

nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

4.啟動nginx

cd /app/nginx/
/sbin/nginx   //啟動nginx

瀏覽器輸入服務器ip，證明成功

 

已上成功的顯示

下面是有可能失敗的原因

1../sbin/nginx -t 命令后，出現以下錯誤

nginx: [alert] could not open error log file: open() "/opt/nginx-1.10.3//logs/error.log" failed (13: Permission denied)
nginx: the configuration file /opt/nginx-1.10.3//conf/nginx.conf syntax is ok
2019/01/06 21:47:53 [emerg] 22206#0: open() "/opt/nginx-1.10.3//logs/nginx.pid" failed (13: Permission denied)
nginx: configuration file /opt/nginx-1.10.3//conf/nginx.conf test failed

(1) 表示nginx下沒有error.log的文件

   解決方法: nginx文件夾下新建logs文件夾

mkdir logs

chmod 700 logs

然后再次執行 ./sbin/nginx -t

然后執行./sbin/nginx，此時出現

2017/09/19 11:07:26 [emerg] 5580#3332: bind() to 0.0.0.0:80 failed (10013: An attempt was made to access a socket in a way forbidden by its access permissions)
2017/09/19 11:09:35 [emerg] 7552#7556: bind() to 0.0.0.0:80 failed (10013: An attempt was made to access a socket in a way forbidden by its access permissions)

原因是只有root權限的用戶可以conf的端口是1024以下，其他用戶只能1024以上，所以在nginx/conf/nginx.conf下面把80端口號改為8080即可

(1)查詢nginx啟動的服務  

ps –ef | grep nginx

(2)殺掉所有的進程

kill -9 sth

(3)重新啟動nginx即可

 

 

 然后輸入ip+端口號

 

 

 

 

最后把前端代碼打包，然后配置nginx.conf文件，然后直接重啟nginx。輸入你的ip+端口即可出現相應的前端界面。

注:如果后台服務和前端服務不在同一個端口，要在nginx.conf的文件中配置反向代理，否則接口會報405錯誤
