Shell Script-page static

Real needs:

For some pages that are not real-time, the data changes are not very large pages, we can make this JSP or Freemark page static.

Such a benefit, when our service hangs up, through Nginx's agent, we can still access the relevant page.

Realize:

Through the shell script and the Linux crontab Timer task implementation. This is just about how to implement the script.

1. First we will learn to use the Curl script:

Download a single file and print the output to standard output (STDOUT) by default

Curl http://www.centos.org

Save the downloaded file to the specified file with the-o/-o option:

-O: Save the file as the file name specified on the command line

-O: Save the file to local using the default file name in the URL

# Download the file locally and name it mygettext.html

Curl-o mygettext.html http://www.gnu.org/software/gettext/manual/gettext.html

# Save the file locally and name it gettext.html

Curl-o http://www.gnu.org/software/gettext/manual/gettext.html

Example 1:index.sh the specific script is as follows: Description:1.http://127.0.0.1:8082/index?clean=true  is a JSP page provided by our native container service. 2.status1 ,status2,status3,status  is to determine whether the JSP page returned by the service is legitimate,   is implemented according to your JSP page. Because once the JSP page is wrong, returning the wrong page overwrites the good page,   static is meaningless. The 3.cp ,mv  operation is to back up and overwrite the current static page. For simple usage of   4.sed, the operation of SED is not necessary. http://www.cnblogs.com/dong008259/archive/2011/12/07/2279897.html#!/bin/sh#resin index#/opt/www/pages/ Index.tmp#index pagehttp_code= ' Curl -o /opt/www/pages/index.tmp -s -w %{http_ Code} http://127.0.0.1:8082/index?clean=true ';if [ ${http_code} -eq 200 ]     then    status1= ' Cat /opt/www/pages/index.tmp |grep -o   "Content_item" |wc -l '     status2= ' Cat /opt/www/pages/index.tmp |grep  -o  "Photocdn" |wc -l '     status3= ' cat /opt/www/pages/index.tmp | grep -o   "Focus" |wc -l ' &NBsp;   status= ' cat /opt/www/pages/index.tmp |grep -o  "Data-columnid" |WC  -l '    # echo  ' ${status1},${status2},${status3},${status} '      if [ ${http_code} -eq 200 ] && [ ${status} -ge  15 ] && [ ${status1} -ge 80 ] && [ ${ status2} -ge 80 ] && [ ${status3} -ge 1 ]         then         date= ' date  + "%y-%m-%d-%h-%m" ';         cp /opt/www/pages/index.html /opt /www/pages/index.${date};        mv /opt/www/pages/index.tmp  /opt/www/pages/index.html;         #debug_str = ' <!--' Date  + "%y-%m-%d-%h-%m"          #sed  -i  ' 1a\ ' ${debug_str} /opt/www/pages/index.html      else        echo  "Build index  ${status} ${status2} ${status3} fail "    fi; else     echo  "build index fail!"; Fi

 Example 4: For example, the head and tail of a generic reference to our website, always change,        We can not change JSP every time to go online. These can have the website of the editing maintenance,        we regularly download the relevant documents just fine.  #!/bin/shwget http://tv.baidu.com/s2012/frag/83/20092861_344978361.inc -q -o /opt/ www/h5-server/web-inf/includes/footer_tmp.jsp >/dev/null 2>&1cd /opt/www/h5-server/ Web-inf/includes/iconv -f gb2312 -t utf-8 footer_tmp.jsp -o footer.jsprm  -rf footer_tmp.jsp       Example 5: If we want to refresh an interface on a timed basis, or periodically let some data flash into the cache. We can also do a timed task of the script, timed execution of the script. #!/bin/shcurl -o /tmp/cooperation.tmp http://localhost:8082/cooperation/listall.json?clean=true  > /dev/null 2>&1exit 0
