linux安装nginx以及nginx部署前端服务

之前没在linux上安装nginx并且部署前端环境，现总结如下

1.下载并解压压缩包

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

//我直接解压，改了名字。即/app/nginx

2.安装nginx

//进入目录
cd nginx
//执行命令
./configure
//执行make命令
make
//执行make install命令
make install

3.检查安装

# cd到刚才配置的安装目录
cd  /app/nginx/

./sbin/nginx -t

正常情况的信息输出：

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.启动nginx

cd /app/nginx/
/sbin/nginx   //启动nginx

浏览器输入服务器ip，证明成功

已上成功的显示

下面是有可能失败的原因

1../sbin/nginx -t 命令后，出现以下错误

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下没有error.log的文件

   解决方法: nginx文件夹下新建logs文件夹

mkdir logs

chmod 700 logs

然后再次执行 ./sbin/nginx -t

然后执行./sbin/nginx，此时出现

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权限的用户可以conf的端口是1024以下，其他用户只能1024以上，所以在nginx/conf/nginx.conf下面把80端口号改为8080即可

(1)查询nginx启动的服务  

ps –ef | grep nginx

(2)杀掉所有的进程

kill -9 sth

(3)重新启动nginx即可

 然后输入ip+端口号

最后把前端代码打包，然后配置nginx.conf文件，然后直接重启nginx。输入你的ip+端口即可出现相应的前端界面。

注:如果后台服务和前端服务不在同一个端口，要在nginx.conf的文件中配置反向代理，否则接口会报405错误
