An operation example of online mall migration

Online mall migrates and modifies database password and IP

Let's take one of the malls as an example, and all the other malls have the same operation.

Cd / home/webserver/

Tar zxvf nkwshop.tar.gz

Rm-rf nkwshop.tar.gz

Change IP to new ip

Change mysql password to new password

Vim nkwshop/webapps/onlineshop/WEB-INF/classes/config.properties

Jdbc.url=jdbc:mysql://new IP:3306/nkwshop

Jdbc.password=new password

Cd nkwshop/logs

Rm-rf $tomcat/logs/*

[root@localhost webserver] # ll nkwshop/webapps/

Drwxr-xr-x 16 root root 4096 Apr 5 03:51 onlineshop

Drwxr-xr-x 16 root root 4096 Apr 5 03:51 onlineshopbak

[root@localhost webserver] # rm-f nkwshop/webapps/onlineshopbak

After completing the above three steps, return to the parent directory, pack it, and put it in the tar.gz directory

Tar cvf nkwshop.tar.gz nkwshop

Mv nkwshop.tar.gz tar.gz/

Log in to the database and create a mall database nkwshop

Mysql-uroot-pnew password

Mysql > create database nkwshop

Mysql > show databases

Mysql-uroot-pnew password nkwshop < nkwshop.sql

Mv nkwshop.sql tar.gz

Start the Tomcat service

Nkwshop/bin/startup.sh

Then go to the mall table to find the IP port of the corresponding mall name.

Enter IP (new IP) in the browser: the corresponding mall IP port

If you use IP: Port, it is normal to access several pages in the browser.

Go to the mall form to find the corresponding domain name, and send it to the CDN engineer for domain name resolution.

After the CDN engineer has changed the domain name resolution, he will use the domain name to go to the browser to access the test.
