The whole process of configuring nginx in centos

1. Install the download tool

yum install wget

2. Download nginx

wget http://nginx.org/download/nginx-1.10.2.tar.gz

3. Unzip

tar -xvf nginx-1.10.2.tar.gz

4. compile

./configure && make && make install

An error may be reported during the compilation process, because some dependencies have not been downloaded, you can try to install the dependencies with the following command first, there may be many other dependencies, see the error report for details, and then use the above command to compile

yum install -y pcre-devel zlib-devel openssl-devel 

5. Compile is similar to the installation software in window, and the compilation will automatically install the software to the specified directory /usr/local/

这是nginx的安装目录
/usr/local/nginx

手动启动试试，启动完毕，网页打开ip的80端口，看是不是能够访问，如果不能访问可能是防火墙的问题，关闭防火墙试试
./usr/local/nginx/sbin/nginx

5.1 There are configuration files in the nginx installation directory

配置文件位置，在这里修改配置
/usr/local/nginx/conf/nginx.conf

这是nginx的配置文件的信息
1，一个http下有多个server,每个server监听一个端口
2，一个server下有多个location,每个location监听一个接口

http {

        location / {
    
    
        	# 以下root 右边的html是一个目录名称，和本conf在同一个目录，如客户访问80端口的根目录，
        	nginx就会在html这个目录里寻找 index.html 这个文件，然后渲染给客户看
            root   html;
            index  index.html index.htm;

        #}

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one

        #location ~ /\.ht {

            root   html;
            index  index.html index.htm;
        }}

}

6 In the next article, I will add how to add nginx to the management unit, so as to use systemctl to control nginx, and it is also very convenient to set up the startup
