In MySQL user always tries to connect with the server via command line interface such as remote login like 'ssh' then they troubled themselves in using graphical interface and get the required output quickly. So they need to automate that task. In this Blog I am going to suggest you a way to do this ... First of all we need to know that a MySQL service is kept in /etc/init.d/mysqld and we need to invoke that in order to use mysql server and client. To do this use following command in terminal : service /etc/init.d/mysqld start or service mysqld start When mysql server is started make a directory like /home/anduril/shubham_Script and after entering into that directory use this command in your terminal. vi connect_string.sh It will create a file with the name connect_string.sh you can give any name you want. Press 'i' to edit and enter the following text : mysqlshow -u root -proot mysqladmin version -u root -proot mysqladmin variables -u root -proot mysqladmin ping -u roo...

With the dramatically increasing demand for container orchestration specifically Kubernetes, demand to template K8S manifests(Json/Yaml) also came to light. To handle increasing manifests, new CRDs(Custom resource definition), etc… it became obvious that we need a package manager somewhat like yum, apt, etc… However, the nature of Kubernetes manifest is very different than what one used to have with Yum and Apt. These manifests required a lot of templates which is now supported by Helm, a tool written in GoLang with custom helm functions and pipelines. Neutral background on templating Templating has been a driver for configuration management for a long time. While it may seem trivial for users coming from Ansible, Chef, Puppet, Salt, etc…, it is not. Once one moves to Kubernetes, the very first realization is hard declarative approach that Kubernetes follows. It is difficult to make generic templating with declarative form since each application may have some unique feature and r...

Allowing users to have ssh access Hi Readers, It is one of the tasks we need to complete in order to allow users to log-in into your server without compromising your security. We are going to accomplish the following tasks, 1.) Allow the users for given domain only 2.) Must allow access to a given domain 3.) Block access for a specific domain. These questions are asked in RedHat certification examination RHCE6 We are going to complete the above mention task using iptables To give proper example we are taking 192.168.20.0/255.255.255.0 as our domain and 192.168.21.0/255.255.255.0 as other domain. Assuming that your system is a fresh installation we can remove all rules previously applied. # iptables -F  The above mention command will flush all the previously applied rules. Insert a rule in your input chain by below mention command, # iptables -I INPUT -s <ip of your domain>/<subnet mask> -p <protocal tcp/udp> --dport <port> -...

Edit your Publish settings for Flash SWFs and HTML to reflect how you want your Flash SWF to appear in your web page. Export your Flash movie as HTML. Locate your HTML file on your computer, right-click, and select "Open With". Choose either NotePad or another text editor. Copy the source code from the HTML file. Paste it into your web page's source code in the appropriate location where you want your SWF file to display. Edit the file path to reflect the location of the SWF file on your web server, and upload both your HTML and SWF file to the appropriate directories on your server. ( Note:  this also applies if you're using PHP, JSP, ASP, CGI, or other web page extensions.) Your code should look something like this: <OBJECT classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,0,0" WIDTH="320" HEIGHT="240" id="You...

Change MySQL user's password in bulk Sometimes we need to change the password of mysql users at bulk. Lets say your company has fired a group of peoples or dissolved a project. This requirement can be supplied as : We can achieve the same by changing the password field in mysql.user table. Password() is a predifined method in mysql which generates encrypted value of a certain string. host update mysql.user set password = PASSWORD("passwd") where host IN (<Comma separated list of HostName/IP>); user update mysql.user set password = PASSWORD("passwd") where user IN (<Comma separated list of ‘user’@’host’>);
