Configure Nginx in Linux environment

Linux——centos7 version

Installation environment configuration

1. Nginx is written in C language, so you need to configure the C language compilation environment (to be connected to the Internet)

2. Install the gcc environment

   [root@a ~]# yum install gcc-c++
   已加载插件：fastestmirror, langpacks
   Determining fastest mirrors
    * base: mirrors.aliyun.com
    * extras: mirrors.aliyun.com
    * updates: mirrors.aliyun.com
   base                   
   

3. Solve the problems that occur when installing the gcc environment: Another app is currently holding the yum locak......
   the above problems occur because yum is in a locked state, and it is enough to force the yum process to be shut down

     rm -f /var/run/yum.pid     
   

Installing Nginx requires installing a third-party development package

Installing Nginx requires installing third-party development packages, which are required before compiling

1. PCRE : The http module in nginx uses pcre to parse regular expressions, so the pcre library needs to be installed on linux

   [root@a ~]# yum install -y pcre pcre-devel
   已加载插件：fastestmirror, langpacks
   Loading mirror speeds from cached hostfile
    * base: mirrors.aliyun.com
    * extras: mirrors.aliyun.com
    * updates: mirrors.aliyun.com
    
   

2. zlib : nginx uses zlib to gzio the contents of the http package, so this package needs to be installed

   [root@a ~]# yum install -y zlib zlib-devel
   已加载插件：fastestmirror, langpacks
   Loading mirror speeds from cached hostfile
    * base: mirrors.aliyun.com
    * extras: mirrors.aliyun.com
    * updates: mirrors.aliyun.com
   

3. openssl : openssl is a powerful secure socket layer cipher library, nginx not only supports http protocol, but also supports https, so you need to install openssl library on linux

   [root@a ~]# yum install -y openssl openssl-devel
   已加载插件：fastestmirror, langpacks
   Loading mirror speeds from cached hostfile
    * base: mirrors.aliyun.com
    * extras: mirrors.aliyun.com
    * updates: mirrors.aliyun.com
   

Install Nginx

1. Upload the Nginx source package to Linux

2. Unzip Nginx:[root@a ~]# tar -xvf nginx-1.14.2.tar.gz

3. Create a temporary directorymkdir /var/temp/nginx/client -p

4. Execute the command configure to generate a Mikefile file

   ./configure \
   --prefix=/usr/local/nginx \
   --pid-path=/var/run/nginx/nginx.pid \
   --lock-path=/var/lock/nginx.lock \
   --error-log-path=/var/log/nginx/error.log \
   --http-log-path=/var/log/nginx/access.log \
   --with-http_gzip_static_module \
   --http-client-body-temp-path=/var/temp/nginx/client \
   --http-proxy-temp-path=/var/temp/nginx/proxy \
   --http-fastcgi-temp-path=/var/temp/nginx/fastcgi \
   --http-uwsgi-temp-path=/var/temp/nginx/uwsgi \
   --http-scgi-temp-path=/var/temp/nginx/scgi
   

5. Execute the make command to compile:make

6. Install Nginx:make install
