How to install Nginx and configure automatic startup on CentOS7

1. Download the installation package from the official website

Choose the version suitable for Linux. Here, select the latest version. Download it locally and upload it to the server or download it directly with the wget command under centos.

Switch to the /usr/local directory and download the software package

# cd /usr/local
# wget http://nginx.org/download/nginx-1.11.5.tar.gz

2. Install nginx

First execute the following command to install the nginx dependent library. If the dependent library is missing, the installation may fail. For details, please refer to the error message at the end of the article.

# yum install gcc-c++
# yum install pcre
# yum install pcre-devel
# yum install zlib 
# yum install zlib-devel
# yum install openssl
# yum install openssl-devel

Extract the installation package

# tar -zxvf nginx-1.11.5.tar.gz

nginx was decompressed to the /usr/local/nginx-1.11.5 directory (do not decompress the compressed package to the /usr/local/nginx directory or rename the decompressed directory to nginx (because nginx will be installed in the /usr/local/nginx directory by default), switch to the nginx-1.11.5/ directory

# cd /usr/local/nginx-1.11.5/

Execute # ./configure

# ./configure

This operation will detect the current system environment to ensure that nginx can be successfully installed. After performing this operation, the following prompts may appear:

checking for os

linux 3.10.0-123.el7.x86_64 x86_64

checking for c compiler ... not found

./configure: error: c compiler cc is not found

If the above error message appears, execute yum install gcc-c to install gcc,

./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= option.

If the above prompt appears, it means that the pcre library is missing

./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= option.

If the above prompt appears, it means that the zlib library is missing

If not A ./configure: error prompt appears, indicating that nginx can be installed in the current environment. Execute make and make install to compile nginx

# make
# make install

. If there are no errors, it means that nginx has been successfully installed. The default installation location is /usr/local/nginx , the previous /usr/local/nginx-1.11.5/ can be deleted.

If cp: 'conf/koi-win' and '/usr/local/nginx/conf/koi-win' are the same file appears, it may be that you decompressed the installation package to /usr /local/nginx directory, the solution is to rename the directory to another name and then execute make, make install.

3. Configure nginx to boot up

switch Go to the /lib/systemd/system/ directory and create the nginx.service file vim nginx.service

# cd /lib/systemd/system/
# vim nginx.service

The content of the file is as follows:

[unit]
description=nginx 
after=network.target 
 
[service] 
type=forking 
execstart=/usr/local/nginx/sbin/nginx
execreload=/usr/local/nginx/sbin/nginx reload
execstop=/usr/local/nginx/sbin/nginx quit
privatetmp=true 
 
[install] 
wantedby=multi-user.target

Exit and save the file, execute systemctl enable nginx.service to enable nginx Start up

# systemctl enable nginx.service

systemctl start nginx.service Start nginx

systemctl stop nginx.service End nginx

systemctl restart nginx.service Restart nginx

4. Verify whether the installation is successful

Enter http://server ip/ If you can see the nginx interface, it means the installation is successful
