How to Use the ansible callback plug-in to parse the execution results, ansiblecallback
Recently I was writing a Batch Inspection tool to push the script to each machine using ansible for execution, and then return the execution result in json format.
As follows:
# Ansible node2-m script-a/root/python/health_check.py
node2 | SUCCESS => { "changed": true, "rc": 0, "stderr": "Shared connection to 192.168.244.20 closed.\r\n", "stdout": "{'cpu_iowait': '0.00', 'swap_out': 0, 'cpu_usr
JSON request data is cached Based on backbone and zepto users,
The basic function is to increase the localstorage transfer;
Background Data --"Localstorage-"Page ..
Each time the data is retrieved from localstorage, the background data is updated to localstorage.
Libraries used: zepto. js and backbone. js. Of course, you don't need to use these two libraries for a slight change. I posted them directly. Too lazy to change

One, what is the system average load (load average)?
In Linux systems, the uptime, W, top commands will have the system average load average output, then what is the system average load?
The system average load is defined as the average process tree running in the queue within a specific time interval. A process is located in the run queue if the following conditions are true:
-It is not waiting for the I/O operation results
-It does not actively
How to view system startup time and run time under Linux
1. View/proc/uptime file Computing system startup time:
Cat/proc/uptime
Output: 5113396.94 575949.85
The first number is the system has been running for 5,113,396,.94 seconds, using the System Tools date to calculate the system start time
Date-d "$ (awk-f. ' {print} '/proc/uptime) second ago" + "%y-%m-%

$conn = Dbo.mssql_connect ("61.164.111.245", "Yon", "123456");
$dbname = mssql_select_db ("Yong1", $conn) or Die ("database does not exist or is not available");

I have not had problems with this generation in the generation of the native test
$action =$_post["Action"];
if ($action = = "Commit") {
$id =$_post["id"];
$title =$_post["title"];
$come =$_post["Come"];
$exitt =$_post["Exitt"];
$content =stripslashes (Trim ($_post["content"));

startYou can see that the processes configured are running in the background.
After a process is stopped, the supervisor will immediately restart the process.
Stop a supervisor
sudo /etc/init.d/supervisord stopYou can see that all processes configured are stopped.
You can use supervisorctl to view the process of management and monitoring:
[Op1 @ SVR1631HP360 ~] $ Sudo parse RUNNING pid 27557, uptime 0: 00: Invalid RUNNING pid 27567,
A php update problem. One php update question $ conndbo. mssql_connect (61.164.111.245, yon, 123456); $ dbnamemssql_select_db (yong1, $ conn) ordie (the database does not exist or is unavailable );? I have a php update problem with this generation
$ Conn = dbo. mssql_connect ("61.164.111.245", "yon", "123456 ");
$ Dbname = mssql_select_db ("yong1", $ conn) or die ("The database does not exist or is unavailable ");

I have not encountered any problems in the local testing of this generation.

30 Linux practical commands required by the system administrator
In this article, we will introduce some practical and commonly used Linux or Unix commands, which are commonly used by Linux system administrators. This article is not a complete list, but a brief list of commands that can be used as needed. The following example shows how to use these commands one by one.

In Linux, the uptime
status Ulimit---------system resource Usage limits Mpstat-------------Multi-processor utilization1, uptimeThe uptime command is used to see how long the server has been running and how many users are logged in to quickly learn about the load on the server.The output of the uptime contains a load of average, which shows the last 1, 5, and 15-minute loads. Its value represents the number of processes waiting
