Today, I will talk to you about how to configure nginx in the centos server, many people may not know much about it. In order to make you understand better, the editor has summarized the following content for you. I hope you can get something according to this article.

Download the secure terminal MobaXterm_Personal

First, after downloading the security terminal, connect to your own public network IP

After the connection is successful, it is shown as above.

Introduction to Nginx

Nginx is a lightweight web server and reverse proxy server. Compared with Apache and lighttpd, it has the advantages of less memory and high stability. Its most common use is to provide reverse proxy service

After connecting to the server

Step 1: install gcc gcc-c++

The command is:

Yum install-y gcc gcc-c++

Step 2: install the PCR library

$cd / usr/local/$ wget http://jaist.dl.sourceforge.net/project/pcre/pcre/8.33/pcre-8.33.tar.gz$ tar-zxvf pcre-8.36.tar.gz$ cd pcre-8.36 $. / configure$ make & & make install

If you report an error: configure: error: You need a C++ compiler for C++ support

Solution: yum install-y gcc gcc-c++

Step 3: install the SSL library

$cd / usr/local/$ wget http://www.openssl.org/source/openssl-1.0.1j.tar.gz$ tar-zxvf openssl-1.0.1j.tar.gz$ cd openssl-1.0.1j$. / config$ make & & make install

Step 4: install zlib inventory

$cd / usr/local/$ wget http://zlib.net/zlib-1.2.11.tar.gz$ tar-zxvf zlib-1.2.11.tar.gz$. / configure$ make & & make install

Step 5: install nginx

Cd / usr/local/$ wget http://nginx.org/download/nginx-1.8.0.tar.gz$ tar-zxvf nginx-1.8.0.tar.gz$ cd nginx-1.8.0 $. / configure-- user=nobody-- group=nobody-- prefix=/usr/local/nginx-- with-http_stub_status_module-- with-http_gzip_static_module-- with-http_realip_module-- with-http_sub_module-- with-http_ssl_module (note:-- with-http_ssl_module: this is not followed after nginx.conf configures ssl:on Startup will report nginx: [emerg] unknown directive "ssl" in / opt/nginx/conf/nginx.conf exception) $make & & make install

Start nginx

$/ usr/local/nginx/sbin/nginx

Step 6: check whether the startup is successful

Open a browser to access the IP of this machine, if the browser appears Welcome to nginx! Then Nginx is installed and running successfully.

Record what happened to me in the process:

At step 6, the connection to the browser was unsuccessful and there was no response, so I checked whether port 80 of the firewall was open.

The command is:

Firewall-cmd-- list-all check port 80

Firewall-cmd-- zone=public-- add-port=80/tcp if port 80 is not open, open port 80

Firewall-cmd-- reload reopens the firewall

Restart the nginx service again:

/ usr/local/nginx/sbin/nginx-s reload

Found or unable to connect to this IP address, check that the local connection is normal:

The command is:

Curl localhost

Displayed as a picture, it is found that the local connection is successful, but ip just cannot access it.

Finally, it was found that because of the new server, Aliyun Security Group only opened ports 22 and 3389, but did not open port 80.

Only these two port numbers are not enough, and port 80 needs to be opened in order to link to the server.

Add configuration rules for security groups

Since Aliyun is used, we will use the security group operation of Aliyun to achieve the opening effect of the port.

After logging in to Ali Cloud, select in the following order: CVM ECS- > Security Group-> configuration rules

At present, there are three security group rules, which are 22prime3389 and ICMP protocol.

Then click add Security Group Rule in the upper right corner

Add port 80

As shown in the figure, you only need to modify two:

Port range: 21: 21 indicates that it starts at 21 and ends at 21.

Authorization object: 0.0.0.0 ip 0 means that all port addresses can access the port

As shown in the figure, a new rule has been added
