Nginx brief installation and configuration example analysis

1. Files required for nginx installation

1), nginx-1.2.8.tar.gz

2), openssl-1.0.1g.tar .gz

3), pcre-8.31.tar.gz

4), zlib-1.2.7.tar.gz

The download addresses of the above installation packages are available normally. , since I am using the installation package of the above version, the following installations are based on this.

2. Linux machine configuration environment

2.1.java environment

$java -version
java version "1.8.0_45"
java(tm) se runtime environment (build 1.8.0_45-b14)
java hotspot(tm) 64-bit server vm (build 25.45-b02, mixed mode)

2.2.Hardware configuration

3. Installation steps

3.1. Unzip the installation package

Enter the nginx installation directory and unzip openssl-1.0.1g.tar.gz and pcre respectively -8.31.tar.gz, zlib-1.2.7.tar.gz, nginx-1.2.8.tar.gz four tar packages, execute the command tar -zxvf xxxx.tar.gz, where xxxx is the package name.

After decompression:

3.2. Compile the installation package

First compile the 3 required Library file packages: openssl-1.0.1g, pcre-8.31, zlib-1.2.7.

Compile openssl-1.0.1g, enter the file directory, and execute the following commands in sequence:

$./config$make$make install

Normal installation result:

Compile pcre-8.31, enter the file directory, and execute the following commands in sequence:

$./config
$make
$make install

Normal installation result:

Compile zlib-1.2.7, enter the file directory, and execute the following commands in sequence:

$./configure
$make
$make install

Normal installation results:

Next, Compile the nginx installation package, enter the file directory, and execute ./configure. You need to specify the installation directory –prefix=/opt/nginx/nginx and the path of the corresponding library file

sudo ./configure --prefix=/opt/nginx /nginx --with-openssl=/opt/nginx/openssl-1.0.1g --with-pcre=/opt/nginx/pcre-8.31 --with-zlib=/opt/nginx/zlib-1.2.7

Next, compile and install.

Copy code The code is as follows:

sudo ./configure --prefix=/opt/nginx/nginx --with-openssl=/opt/nginx/openssl-1.0.1g --with -pcre=/opt/nginx/pcre-8.31 --with-zlib=/opt/nginx/zlib-1.2.7

Next, compile and install.

$make
$make install

At this point, the nginx installation is completed.

3.3. Start nginx

Enter the nginx installation directory/opt/nginx/nginx/sbin and execute ./nginx to start the service.

[dddd.et15sqa /opt/nginx/nginx/sbin]

$sudo ./nginx

View the service process after startup:

$ps aux|grep nginx
root 2295 0.0 0.0 28264 804 ? ss 23:30 0:00 nginx: master process ./nginx
nobody 2296 0.0 0.0 28660 1356 ?      s   23:30 0:00 nginx: worker process
125233 2411 0.0 0.0 113720 1012 pts/0 s 23:31 0:00 grep nginx

Open nginx default homepage:

#Service installation and startup OK!

4. Port forwarding

You need to forward port 80 to the tomcat homepage running in the server, and its port is 8080.

tomcat home page:

## Configure the nginx.conf file of nginx as follows:

server {
    listen    80;
    server_name 127.0.0.1;

    #charset koi8-r;

    #access_log logs/host.access.log main;

    location / {
      #root  html;
      #index index.html index.htm;
      proxy_set_header host $host;
      proxy_set_header x-real-ip $remote_addr;
      proxy_set_header x-forwarded-for $remote_addr;
      proxy_pass http://127.0.0.1:8080;
    }

Restart the nginx service, ./nginx -s reload

At this time, you can access port 80, but it actually jumps to the service of port 8080.
