Determine if the remote Web server status code is healthy through scripting

Determine if the remote Web server status code is healthy through scripting

1. Description

   (1) A list of common HTTP status codes for production environments, please check out my blog: http://wutengfei.blog.51cto.com/10942117/1934645

   (2) Remote NGINX server IP address in experiment: 192.168.100.114

   Local client IP address: 192.168.100.118

2. The script is as follows

Method 1:if

#!/bin/bash

Httpcode= ' curl-i-S 192.168.100.114|head-1|cut-d ""-f2 '

If ["$httpcode" = = "];then"

echo "Nginx is running."

Else

echo "Nginx is not running."

Fi

The validation results are as follows:

Open Nginx Service

650) this.width=650; "src=" Https://s2.51cto.com/wyfs02/M01/9B/B8/wKiom1lmMUOB2nAXAAANTG3xlxk248.png "title=" 11. PNG "alt=" Wkiom1lmmuob2naxaaantg3xlxk248.png "/>

Execute the script on the client:

650) this.width=650; "src=" Https://s3.51cto.com/wyfs02/M00/9B/B8/wKiom1lmMYqRx47cAAAJRXT2nq0061.png "title=" 11. PNG "alt=" Wkiom1lmmyqrx47caaajrxt2nq0061.png "/>

Now close Nginx Service:

650) this.width=650; "src=" Https://s3.51cto.com/wyfs02/M02/9B/B8/wKiom1lmMfaDpi6bAAAWBZvSb34855.png "title=" 11. PNG "alt=" Wkiom1lmmfadpi6baaawbzvsb34855.png "/>

Execute the script on the client:

650) this.width=650; "src=" Https://s5.51cto.com/wyfs02/M01/9B/B7/wKioL1lmMlewhffLAAAJ74AnXAQ995.png "title=" 11. PNG "alt=" Wkiol1lmmlewhfflaaaj74anxaq995.png "/>

Method 2: Use the pass-through parameter

#!/bin/bash

If [$#-ne 1];then

echo "usage:$0 IP port."

Fi

Httpcode= ' curl-i-S $1|head-1|cut-d ""-f2 '

If ["$httpcode" = = "];then"

echo "Nginx is running."

Else

echo "Nginx is not running."

Fi

The validation results are as follows:

Open Nginx Service

650) this.width=650; "src=" Https://s2.51cto.com/wyfs02/M01/9B/B8/wKiom1lmMUOB2nAXAAANTG3xlxk248.png "title=" 11. PNG "alt=" Wkiom1lmmuob2naxaaantg3xlxk248.png "/>

Execute the script on the client:

650) this.width=650; "src=" Https://s2.51cto.com/wyfs02/M02/9B/B8/wKioL1lmOMSg6Iz6AAALjClRT6g702.png "title=" 11. PNG "alt=" Wkiol1lmomsg6iz6aaaljclrt6g702.png "/>

Now close Nginx Service:

650) this.width=650; "src=" Https://s3.51cto.com/wyfs02/M02/9B/B8/wKiom1lmMfaDpi6bAAAWBZvSb34855.png "title=" 11. PNG "alt=" Wkiom1lmmfadpi6baaawbzvsb34855.png "/>

Execute the script on the client:

650) this.width=650; "src=" Https://s4.51cto.com/wyfs02/M01/9B/B9/wKiom1lmOSTxnkybAAANdoZY5QM869.png "title=" 11. PNG "alt=" Wkiom1lmostxnkybaaandozy5qm869.png "/>

Method 3: Using read, the interface is relatively friendly

#!/bin/bash

Read-p "Please input IP:" A

If [-Z $a];then

echo "usage:$0 please input IP."

Fi

Httpcode= ' curl-i-S $a |head-1|cut-d ""-f2 '

If ["$httpcode" = = "];then"

echo "Nginx is running."

Else

echo "Nginx is not running."

Fi

The validation results are as follows:

Method 4: Use the function

#!/bin/bash

[-f/etc/init.d/functions] &&. /etc/init.d/functions | | Exit 1

Read-p "Please input IP:" A

Httpcode= ' curl-i-S $a |head-1|cut-d ""-f2 '

If ["$httpcode" = = "];then"

Action "Nginx is running."/bin/true

Else

Action "Nginx is not running."/bin/false

Fi
