Detailed explanation of installing and configuring nginx under Linux

1. Install and configure nginx under Linux

When installing nginx for the first time, any problems that arise in the process will be solved step by step.

The tool used is secureCRT, connect and log in to the server.

1.1 rz command, a dialog box will pop up, select the nginx compressed package to be uploaded.

#rz

1.2 Unzip

[root@vw010001135067 ~]# cd /usr/local/
[root@vw010001135067 local]# tar -zvxf nginx-1.10.2.tar.gz

1.3 Enter the nginx folder and execute the ./configure command

[root@vw010001135067 local]# cd nginx-1.10.2
[root@vw010001135067 nginx-1.10.2]# ./configure

The error is reported as follows:

checking for OS
 + Linux 2.6.32-431.el6.x86_64 x86_64
checking for C compiler ... not found
 
./configure: error: C compiler cc is not found

This error occurs. Then the gcc package is not installed.

1.3.1 Install gcc

View gcc

[root@vw010001135067 nginx-1.10.2]# whereis gcc
gcc:

Install gcc

[root@vw010001135067 nginx-1.10.2]# yum -y install gcc

After successful installation Check again

[root@vw010001135067 nginx-1.10.2]# whereis gcc
gcc: /usr/bin/gcc /usr/lib/gcc /usr/libexec/gcc /usr/share/man/man1/gcc.1.gz

gcc is installed.

1.3.2 Continue executing ./configure

[root@vw010001135067 nginx-1.10.2]# ./configure

./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.

The above error occurs. Install pcre-devel

[root@vw010001135067 nginx-1.10.2]# yum install pcre-devel

1.3.3 Execute again./configure

error: the HTTP gzip module requires the zlib library.
You can either disable the module by using --without-http_gzip_module
option, or install the zlib library into the system, or build the zlib library
statically from the source with nginx by using --with-zlib=<path> option.

If there is this error then execute

yum install zlib-devel

1.3.4 No error is reported after executing ./configure

[root@vw010001135067 nginx-1.10.2]# ./configure

1.4 If you want to use openssl function, sha1 function. Then install openssl, sha1

[root@vw010001135067 nginx-1.10.2]# yum install openssl openssl-devel
[root@vw010001135067 nginx-1.10.2]# install perl-Digest-SHA1.x86_64

1.4.1 Enable ssl module execution./configure –with-http_ssl_module

[root@vw010001135067 nginx-1.10.2]# ./configure --with-http_ssl_module

1.4.2 Enable "server+status" page, execute ./configure –with-http_stub_status_module

[root@vw010001135067 nginx-1.10.2]# ./configure --with-http_stub_status_module

The above two commands can be started at the same time

[root@vw010001135067 nginx-1.10.2]# ./configure --with-http_stub_status_module --with-http_ssl_module

1.5 The above configure has passed

Execute the make command and execute the make install command

[root@vw010001135067 nginx-1.10.2]# make
[root@vw010001135067 nginx-1.10.2]# make install

At this point, nginx has been executed successfully

1.6 Configure environment variables

In /etc /profile Add configuration

Open the configuration file

[root@vw010001135067 nginx-1.10.2]# vi /etc/profile

Add

#nginx configure
export NGINX_HOME=/usr/local/nginx-1.10.2
export PATH=$PATH:$NGINX_HOME/sbin

to the configuration file

I started to fill it in as above, but it couldn’t be found when running nginx -v. Noticed that the address of my nginx_home configuration above is wrong. First find the installation address of nginx

[root@vw010001135067 nginx-1.10.2]# whereis nginx
nginx: /usr/local/nginx

The address is really wrong, change the above to

#nginx configure
export NGINX_HOME=/usr/local/nginx
export PATH=$PATH:$NGINX_HOME/sbin

After compiling, save, exit and execute

[root@vw010001135067 nginx-1.10.2]# source /etc/profile

to make the configuration take effect.

1.7 Check nginx version

[root@vw010001135067 nginx]# nginx -v
nginx version: nginx/1.10.2

The whole process was successful!

2. Modify nginx.conf

2.1 Start nginx

My nginx service is at http://10.1.135.67/. After the configuration is successful, start nginx now

[root@vw010001135067 nginx]# cd /usr/local/nginx
[root@vw010001135067 nginx]# nginx -c conf/nginx.conf

Start successfully, open http://10.1.135.67/ in the browser, the default port number is 80.

As shown above, nginx is already working normally.

2.2 Configure tomcat service

Now my tomcat service is at 10.1.29.15 and needs to be forwarded through nginx. Then open nginx.conf and modify the configuration file. As follows, add:

#user nobody;
worker_processes 1;
 
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
 
#pid  logs/nginx.pid;
 
 
events {
 worker_connections 1024;#最大连接数，默认为512
 accept_mutex on; #设置网路连接序列化，防止惊群现象发生，默认为on
 multi_accept on; #设置一个进程是否同时接受多个网络连接，默认为off
 #use epoll;  #事件驱动模型，select|poll|kqueue|epoll|resig|/dev/poll|eventport 
}
 
 
http {
 #文件扩展名与文件类型映射表
 include  mime.types;
 
 #默认文件类型，默认为text/plain 
 default_type application/octet-stream;
 
 #自定义格式
 log_format main '$remote_addr - $remote_user [$time_local] "$request" '
      '$status $body_bytes_sent "$http_referer" '
      '"$http_user_agent" "$http_x_forwarded_for"'; 
 
 #combined为日志格式的默认值
 access_log logs/access.log main;
 
 #允许sendfile方式传输文件，默认为off，可以在http块，server块，location块
 sendfile  on;
 sendfile_max_chunk 100k; #每个进程每次调用传输数量不能大于设定的值，默认为0，即不设上限。
 
 #tcp_nopush  on;
 
 #连接超时时间，默认为75s，可以在http，server，location块。
 keepalive_timeout 65;
 
 #gzip on;
 
 upstream upload {
  server 10.1.29.15:8080;
 }
 
 error_page 404 https://www.baidu.com; #错误页
 
 server {
  keepalive_requests 120; #单连接请求上限次数。
  listen  80; #监听端口
  server_name localhost; #监听地址 
 
  #charset koi8-r;
 
  #access_log logs/host.access.log main;
 
  location ~ ^.*?/upload/[^/]*?$ {
   proxy_connect_timeout 15;
   proxy_send_timeout 15;
   proxy_read_timeout 15;
   proxy_set_header Host $host;
   proxy_set_header X-Real-IP $remote_addr;
   proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
   proxy_set_header Connection "";
   proxy_pass http://upload; #请求转向upload 定义的服务器列表
   client_max_body_size 1024m;
} 
 }
}

After configuration, save the configuration file and restart nginx

[root@vw010001135067 nginx]# nginx -s reload

Whether calling the upload project in the browser is successful

As shown in the figure, the project can be accessed correctly and the configuration is successful!

The above is the entire content of this article. I hope it will be helpful to everyone's learning. I also hope that everyone will support the PHP Chinese website.
