Production environment server environment setup + project release process

Production environment server environment setup ( install jdk+ File permissions +tomcat+Nginx+Postgres )+ Project release process

install jdk

install openjdk-8-jdk stay ubuntu-16.04 The following commands are used in the system :

• 1.sudo add-apt-repository ppa:jonathonf/openjdk
• 2.sudo apt-get update
• 3.sudo apt-get install openjdk-8-jdk

Input java -version Check to see if it is installed correctly , Output is as follows ：

openjdk version "1.8.0_191"

OpenJDK 64-Bit Server VM (build 25.191-b12, mixed mode)

Create a publishing Directory , And give corresponding permissions

• home/beeoz/sites ( Servers and background folders )
• home/beeoz/tmp ( Upload front-end folder )

Change document ownership chown

• myfile Ownership of the document becomes username：sudo chown username myfile
• Add parameters -R,work The ownership of the folder and all the files and subdirectories in the folder becomes username：chown -R username /files/work

Change file permissions chmod

• sudo chmod 777 filename
• sudo chmod -R 754 director
• 4 Can be read ,
  2 Can write ,
  1 Executable
  0 No authority
  The sequential allocation of three numbers represents the user 、 User group 、 other . The first number 7 Indicates that the user's permission is read + Write + perform （4+2+1=7）, The second number 5 Indicates that the permission of the user group is read + Executable （4+0+1=5）, The third number 4 Indicates that the permission of others is to read （4+0+0=4）

install tomcat The server

• 1. install tomcat8 Cannot be installed in the system directory , Install in user directory , The operating commands in the system directory are inconsistent with the normal commands
• 2. to update sudo apt-get update
• 3. download wget http://ftp.riken.jp/net/apache/tomcat/tomcat-8/v8.5.35/bin/apache-tomcat-8.5.35.tar.gz
• 4. Unzip to sites In the folder tar -zxvf ~/apache-tomcat-8.0.33.tar.gz -C ~/sites

The following can be added without configuration ( Change to production environment )

• cp catalina.sh catalina.sh.date
• vi catalina.sh
• JAVA_OPTS=’-Dspring.profiles.active=prod -Xms512m -Xmx2048m -XX:PermSize=256M -XX:MaxNewSize=256m -* XX:MaxPermSize=256m’

Be careful , This release will sites Medium tomcat-8.0.33 Renamed as wms

To configure Nginx Service forwarding Tomcat

• sudo apt-get install nginx
• sudo vim /etc/nginx/sites-available/default

default

server {
    listen 80 default_server;
    listen [::]:80 default_server;

    root /home/beeoz/sites/wms/webapps/wms;

    # Add index.php to the list if you are using PHP
    index index.html index.htm index.nginx-debian.html;
    # server_name _;

    server_name vpshw1.taoware.com;

    location / {
            # First attempt to serve request as file, then
            # as directory, then fall back to displaying a 404.
            # try_files $uri $uri/ =404;
            # proxy_pass http://114.116.22.35:8080/wms;
            proxy_set_header X-Forwarded-Host $host;
            proxy_set_header X-Forwarded-Server $host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

            proxy_pass http://localhost:8080/wms/;
    }

• sudo nginx -c /etc/nginx/nginx.conf start-up nginx
• Open your website to watch , Note the ports of the firewall and the server security group
• nginx -s stop Stop the order
• nginx -s reload Download the configuration file again
• sudo service nginx restart restart
• service nginx {start|stop|status|restart|reload|configtest|}

install Postgres Database services

• Please refer to ： https://www.cnblogs.com/zhaojonjon/p/7682187.html

Management database

• sudo -u postgres psql
• postgres=# create database Library name ;
• postgres=# create user user name ;
• postgres=# alter user user name password ‘ password ’;
• postgres=# alter user duye createrole createdb replication login;
• postgres=# \l view the database
• postgres=# \du View users and corresponding permissions

Project release

Preparation before project packaging

• Change the data connection information before packaging the project （ Illustrate with examples ：1. Change the database name to wms, User name changed to beeoz, Change the password to BeeOz2018）, The specific editing position is as follows ：

application-prod.yml

spring:
	devtools:
    	restart:
       		enabled: false
    	livereload:
        	enabled: false
	datasource:
    	type: com.zaxxer.hikari.HikariDataSource
    	url: jdbc:postgresql://localhost:5432/wms125
    	username: beeoz
    	password: BeeOz2018

Project package

• 1. Background project packaging command （cmd Enter the root directory file ）：gradle --stacktrace -Pprod bootRepackage ; Store in APP In the project libs Under the document ： The package file name is wms-0.0.1-SNAPSHOT.war
• 2. Front end packaging command ：cnpm run build ; The project is stored in dist In the folder , First, compress the two queries into a file in the resource directory dist.zip

Operating commands in the server

• 1. Connect to server ： Jump to /sites/wms Under the table of contents
• 2. Run the command to shut down the server ./bin/shutdown.sh
• 3. Backup under the same directory ：mv webapps webapps.9.5（webapps.9.5 Yes, for example ）
• 4. Create a folder under the same directory ：mkdir webapps
• 5. Jump to the new folder ：cd webapps
• 6. Put the local background items under this folder through the price inquiry transmission tool
• 7. Run in the same directory ： mv wms- 0.0.1-SNAPSHOT.war wms.war Generate wms.war file
• 8. Go back to the previous Directory , Then enter logs Delete all items in the directory log： rm *
• 9. return wms Under the table of contents , Start the server ： ./bin/startup.sh
• 10. Check the console log ： tail -f logs/catalina.out

If you want to modify the contents of the configuration file or related files

Modify the configuration file

• 1. go in wms Folder
• 2."./bin/shutdown.sh"
• 3. function "vi ./WEB-INF/classes/config/application-prod.yml"
• 4. Edit and save exit
• 5. Restart ：./bin/startup.sh
• 6. View console ：tail -f logs/catalina.out

Front end publishing project

• 1. First of all to enter tmp Empty directory
• 2. take dist.zip Copy the compressed file to this directory
• 3. Run the command to unzip ：unzip dist.zip
• 4. Get into dist: cd dist
• 5. Run the command to see ：ls
• 6. Run the command and copy it to the corresponding directory ： mv * ~/sites/wms/webapps/wms/

Release process considerations

• You can change the name of the server before it starts mv irengine-wms-app-0.0.1-SNAPSHOT.war wms.war
• Can be dist Move the contents of to wms The original stage file should be saved before index.html File name is another name
• Before releasing a new version webapps Backup of the original project in
• If you need to update the version, you can logs Backup ; If not, please send logs Clear the log in and run the start server command
• The foreground decompression needs to be installed unzip Tools （ install unzip: sudo apt install unzip）
• Upload tools can be selected filezilla Tools such as , Before uploading, you need to confirm whether the modified folder has permission to receive
