Using SNMP for administ PogoPlug
Oct 14, 2013Technology
###Preparation For using SNMP for administrating PogoPlug, we have to install following packages first:
# apt-get install snmpd smartmontools super
snmpd is the daemon process for snmp, smartmontools is the monitor tools for harddisk, super let you run daemon process in super priviledge.
###Configuration
Configure snmp firstly.
###Client Configuration Install the webserver using the following command:
$ pacman -S apache php php-apache mariadb
After install the packages, if you want to change the configuration file, directly edit the /etc/httpd/conf/httpd.conf or extra/httpd-default.conf, then using systemd to restart the httpd daemon.
Change priviledge of the public_html directory:
$ chmod o+x ~
$ chmod o_x ~/public_html
# A more safe way for controlling the safety
# usermod -aG groupname http
###SSL Configuration Generate a new self-signed certificate(key size and the number of days of validity will be customized):
# openssl genrsa -out server.key 2048
Generating RSA private key, 2048 bit long modulus

[root@XXXyyy conf]# ls
extra httpd.conf magic mime.types server.key
[root@XXXyyy conf]# chmod 600 server.key
[root@XXXyyy conf]# openssl req -new -key server.key -out server.csr
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]:
State or Province Name (full name) [Some-State]:
Locality Name (eg, city) []:
Organization Name (eg, company) [Internet Widgits Pty Ltd]:
Organizational Unit Name (eg, section) []:
Common Name (e.g. server FQDN or YOUR name) []:
Email Address []:
Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:
[root@XXXyyy conf]# openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt
Signature ok
subject=/C=AU/ST=Some-State/O=Internet Widgits Pty Ltd
Getting Private key
[root@XXXyyy conf]# ls
extra httpd.conf magic mime.types server.crt server.csr server.key
Then, uncomment the line containing following lines in /etc/httpd/conf/httpd.conf:
Include conf/extra/httpd-ssl.conf
Restart httpd to see the result.
###Enable php Place Following line after LoadModule dir_module modules/mod_dir.so in /etc/httpd/conf/httpd.conf:
LoadModule php5_module modules/libphp5.so
Place following line at the end of the Include list:
Include conf/extra/php5_module.conf
Make sure you uncommented following line:
TypesConfig conf/mime.types
# Optional uncomment:
MIMEMagicFile conf/magic
Add this line in /etc/httpd/conf/mime.types:
application/x-httpd-php php php5
Make sure libphp5.so is under /etc/httpd/modules, if not, you may forgot to install php-apache.
Test the php via following line under test.php:
<?php phpinfo(); ?>
###Configure MariaDB Uncomment at least one line under /etc/php/php.ini:
extension=pdo_mysql.so
