Java Photo Station Beauty Installation Tutorial

Very good picture site source code, you can use it. Reprinted in full.

1. Introduction to Java Photo Station Source Code Beauty

Java photo site, PC version is exposed at 99mm.me, mobile version is exposed at m.99mm.me

I scraped the pages of these two sites and integrated them into a project to determine whether the visitor's device is a PC or a mobile device on the server backend.

The program does application-level caching:

For example, I publish 3 sets of pictures every day. Within the effective time of the cache (24/3=8 hours), a page only accesses the database once and puts the queried data into memory.

This greatly reduces the pressure on the database and improves the response speed of the server.

When a user accesses a set of images in a browser, they only request the website server once.

When you click to view the next picture in the set, use js to modify the picture link.

No need to request the website server, load the image directly from the image server

This program is tested on a server with 512M memory and can respond very quickly.

Specific test environment: Centos7.5 system with 512M memory + JDK1.7 + Tomcat7 + MySQL5.5

It actually occupies about 300M of memory, and the rest is cached.

The meaning of the database table fields can be found in the comments of domain in the source code. I am too lazy to write it here.

Please refer to the image link in my.properties and change it yourself

Change the database configuration in jdbc.properties according to the situation

There are 3 default categories: sexy, beautiful legs, pure

I wrote the code in the JDK 1.8 environment and used Maven to manage the package.

The database table creation language is placed in the resources folder

Local download : iht-Beauty-20181217

2. Install JDK1.7 + tomcat7 + Mysql5.5.61 environment under centos7.5 64 bit

1. Installation of JDK 1.7

View the installable JDK

Select the 64-bit 1.7 version java-1.7.0-openjdk.x86_64 here
Installation Commands

Check whether the installation is successful

If the version information appears, it means the installation is successful.

(II) Installation of Tomcat

Tomcat7 installation command >>> Soha <<<, copy all the following and paste it:

Enter the local folder

Go to the official website to find the download link of Tomcat and download it to the server. Here is a quick download address for Tomcat:

Unzip this folder:

Rename this file:

Note: Renaming is for the convenience of subsequent operations. It is not necessary to enter the bin folder.

Grant permissions to all shell scripts in this folder:

Start the tomcat service:

Check whether Tomcat is started successfully

(III) Installation of MySQL 5.5.61

a. Installation preparation

CentOS7 Mariadb database, uninstall first

Method 1: rpm

Find Version

uninstall

mariadb-libs-5.5.56-2.el7.x86_64 is the version in the current system. You can delete the configuration file according to the actual changes.

Method 2: yum
Find

uninstall

Here mariadb-libs.x86_64 is the corresponding version to delete the configuration file

b. Detailed installation

1. Download MySQL Community Server 5.5.61 from the official website
Select Operating System: Select Linux Genuric
Select OS Version: Select the corresponding bit number. This time, select 64-bit and click the download button. If you are asked whether to log in, do not log in. Just copy the link below No thanks, just start my download.:
https://dev.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.61-linux-glibc2.12-x86_64.tar.gz
2. Switch to the local folder

3. Download mysql to the server

4. Unzip

5.Change the folder name, pay attention to the folder name..

6. Modify the my.cnf configuration file

Add the following to my.cnf

7. Switch to the mysql directory

8. Add user groups and users. Here you need to switch the directory to the mysql directory.

9. Install MySQL

10. Configure Mysql

11. Start the service

There may be an error here

Create the required directories and grant permissions:

12. Configure PATH

Add the following content to the end of the file and save it using: wq

13. Refresh PATH

11. Start the service

14. Log in to mysql. There is no password for mysql at this time. When Enter password: appears, press Enter directly

15. Change the root password

16. Set up remote login

Notice:
Note: For Linux MySQL, the default case sensitivity is indicated.

3. Installation of Beauty Photo Station

Import the above database file (beauty.sql) into your database

Then unzip the Beauty.zip package

Go to Beauty–>WEB-INF–>classes, modify the jdbc.properties file, and modify the last 3 lines, which are the address of your database: port/account/password

Then transfer the Beauty folder to the server

Here I created it in the server root directory

 /www/webapps/

folder, and then put the Beauty folder in it

The final path is /www/webapps/Beauty

This will be used when configuring the following

Then enter in ssh

 cd /usr/ local /tomcat7/ conf vi server.xml

Change the line 71 or so below

 < Connector port = "8080" protocol = "HTTP/1.1" connectionTimeout = "20000" redirectPort = "8443" />

Change 8080 in the command to the port you want to configure. The easiest way is to change it to 80. You don't need to add a port to access it.

Then press the arrow key to the end and add a line above the </Host> node. Here is mine:

 < Context docBase = "/www/webapps/Beauty" path = "" />

The value in docBase is the absolute path of the Beauty folder above

Then press Esc + :wq + Enter to save and exit to complete the configuration.

Then restart the Tomcat server.

 cd /usr/ local /tomcat7/bin ./shutdown. sh ./startup. sh

OK, enter your IP or resolved domain name + the port configured above in the browser. If you are accessing through port 80, you don’t need to add the port.
