Recently, nginx web project started to distribute binary packages using nginx yum repository. You can either create \/etc\/yum.repos.d\/nginx.repo or directly install rpm package. This package contains yum configuration file and a public PGP key necessary to authenticate signed RPMs.<\/span><\/p>\n

<\/div>\n

Step #1: Install nginx repo<\/h2>\n
Type the following wget command to install nginx yum configuration
\nfile:
# cd \/tmp<\/code>
CentOS Linux v6.x user type the following command:
# wget http:\/\/nginx.org\/packages\/centos\/6\/noarch\/RPMS\/nginx-release-centos-6-0.el6.ngx.noarch.rpm
# rpm -ivh nginx-release-centos-6-0.el6.ngx.noarch.rpm<\/code>
RHEL v6.x user type the following command:
# wget http:\/\/nginx.org\/packages\/rhel\/6\/noarch\/RPMS\/nginx-release-rhel-6-0.el6.ngx.noarch.rpm
# rpm -ivh nginx-release-rhel-6-0.el6.ngx.noarch.rpm<\/code>
Sample outputs:<\/div>\n
warning: nginx-release-rhel-6-0.el6.ngx.noarch.rpm: Header V4 RSA\/SHA1 Signature, key ID 7bd9bf62: NOKEY

<\/pre>\n
Step #2: Install nginx web-server<\/h2>\n
Type the following yum command to install nginx web-server:
# yum install nginx<\/code>

  4. Default document root directory: \/usr\/share\/nginx\/html<\/kbd><\/li>\n
  5. Default configuration file: \/etc\/nginx\/nginx.conf<\/kbd><\/li>\n
  6. Default server access log file: \/var\/log\/nginx\/access.log<\/kbd><\/li>\n
  7. Default server access log file: \/var\/log\/nginx\/error.log<\/kbd><\/li>\n<\/ol>\n
    To edit the nginx configuration file, enter:
    # vi \/etc\/nginx\/nginx.conf<\/code>
    Set or update worker_processes as follows (this must be set to CPU(s) in your system. Use thelscpu | grep ‘^CPU(s)’<\/a> command to list the number of CPUs in the server)<\/div>\n
    worker_processes  2;<\/pre>\n
    Turn on gzip support:<\/div>\n
    gzip  on;<\/span><\/pre>\n
    Save and close the file. Edit the file \/etc\/nginx\/conf.d\/default.conf<\/kbd>, enter:
    # vi \/etc\/nginx\/conf.d\/default.conf<\/code>
    Set IP address and TCP port number:<\/div>\n
        listen       202.54<\/span>.1<\/span>.1<\/span>.1<\/span>:80<\/span>;<\/span><\/pre>\n
    Set server name:<\/div>\n
        server_name  www.cyberciti.biz;<\/pre>\n
    Save and close the file. Start the server:
    # service nginx start<\/code>
    Verify that everything is working:
    # netstat -tulpn | grep :80
    # ps aux | grep nginx<\/code><\/div>\n
    Firewall configuration: Open TCP port # 80<\/h2>\n
    Edit the file \/etc\/sysconfig\/iptables, enter:
    # vi \/etc\/sysconfig\/iptables<\/code>
