Linux 6 Steps to install and compile Nginx

Linux 6 - The steps for installing Nginx

Preface:

Nginx is a high-performance HTTP and reverse proxy server, as well as an IMAP/POP3/SMTP server. Nginx is a good alternative to Apache for high connection concurrency: Nginx is one of the software platforms of choice for web hosting business owners in the US. Can support responses of up to 50,000 concurrent connections with minimal memory overhead. This is an important reason for Nginx's popularity. This article demonstrates the Nginx based on Linux 6 under the compilation and installation, for your reference.

1. Installation environment

# cat /etc/issue
Red Hat Enterprise Linux Server release 6.3 (Santiago)
Kernel \r on an \m
# nginx -v
nginx version: nginx/1.8.0

2. Configure the installation environment

### To simplify installation and configuration, the firewall is turned off and the production environment is recommended to be turned on 
# service iptables stop
# chkconfig iptables off

# vi /etc/selinux/config 
SELINUX=disabled

### Create users and groups 
#groupadd -r nginx
#useradd -s /sbin/nologin -g nginx -r nginx

### Install environment dependent packages  http://nginx.org/en/linux_packages.html
# yum install pcre-devel zlib-devel openssl openssl-devel gcc gcc-c++

3. Compile and install Nginx

# cd /tmp/
# tar -xvf nginx-1.8.0.tar.gz
# cd /nginx-1.8.0

### Start the nginx
# /usr/sbin/nginx -c /etc/nginx/nginx.conf

# ps -ef|grep nginx|grep -v grep

5. Common faults during installation

./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.

./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.
###  The above 2 An error, please install the corresponding dependency package, see article 2 Section: Configure the installation environment 

# /usr/sbin/nginx 
nginx: [emerg] getpwnam("nginx") failed
###  You need to create nginx User groups and users 

# /usr/sbin/nginx
nginx: [emerg] mkdir() "/var/cache/nginx/client_temp" failed (2: No such file or directory)
###  You need to create the corresponding directory
