Deploy the cow like customer network project on the ECS

Memory is better to have 4g, To run .Nginx Acting as a reverse agent , The forward proxy is the proxy browser , A reverse proxy is a proxy server .Tomcat Yes, it is Java Developed , So the installation Tomcat Before you install JRE; I want to package the program on the server , So the installation Maven, If there are environmental differences , stay windows There may be a problem with packaging and then passing it , So it's best to package on the server . In a real production environment , One software can deploy multiple instances , for example Tomcat,MySQL,Redis etc. . I am learning , Just deploy to a server . visit Linux Virtual machines can use Putty.

Command line file ：

pscp  file name  [email protected] Address :/test

use Bitvise perhaps Xftp Wait for the software to pass .
download unzip, First cd Go to the root , In use yum search

cd /
yum list unzip*
yum install -y unzip.x86_64 java-1.8.0-openjdk.x86_64
java -version

install JRE

Note that the project needs JDK12 To run .

yum list java*
yum install -y 

install Maven

Go to the official website to download 3.6.3 Version of the installation package , Download and install to /opt Under the table of contents

wget -i -c  link 
tar -xzvf apache-maven-3.6.3-bin.tar.gz -C /opt
# Configure environment variables to /etc/profile
vim /etc/profile
# Append after , Save and exit 
export PATH=$PATH:/opt/apache-maven-3.6.3
# Refresh 
source /etc/profile
# Print PATH
echo $PATH
# View version 
mvn -version
# Modification source , Get into conf Folder 
vim settings.xml

stay mirrors Add ：

install MySQL

It has been installed here , To install, please refer to another blog . You can also go to the official website to download yum The corresponding library file , Reuse yum Install library files , Can use yum Download the latest MySQL, install mysql-community-server.x86_64.

yum install -y  Library filename 

start-up mysql：

systemctl start mysqld

see Mysql edition ：

mysql -V

View the generated temporary password ：

grep 'password' /var/log/mysqld.log

After login , Change Password ：

alter user root@localhost identified by ' New password ';

to mysql Import data

unzip -d /test/sql init-sql.zip

Sign in mysql, perform sql file

create database community;
use community;
# Import files 
source /test/sql/init_schema.sql;
source /test/sql/init_data.sql;
source /test/sql/tables_mysql_innodb.sql;
show tables;

Next, we need to header_url Medium localhost Of url Change to a network accessible .

select id,username,header_url from user;
update user set header_url = 'http://images.nowcoder.com/head/492t.png' where header_url like '%localhost%';

install Redis

cd /
yum list redis*
yum install -y redis.x86_64
systemctl start redis
systemctl status redis

test redis

redis-cli
keys *
exit

install kafka

tar -xzvf kafka_2.12-2.3.0.tgz -C /opt
# Enter into config Under the folder 
vim zookeeper.properties
 vim server.properties

Basically, as long as the save path conforms to linux Path specification is OK .
Enter the first kafka The installation path , Don't enter bin Catalog . Because it's the server , It needs to be started in the background .
start-up zookeeper

bin/zookeeper-server-start.sh -daemon config/zookeeper.properties

start-up kafka

nohup bin/kafka-server-start.sh config/server.properties 1>/dev/null 2>&1 &

Test for successful startup kafka

bin/kafka-topics.sh --list --bootstrap-server localhost:9092

If an error is displayed ：

close tomcat, Then execute the above command to restart , And test the .

shutdown.sh

install ElasticSearch

tar -xzvf elasticsearch-6.8.23.tar.gz -C /opt
unzip -d /opt/elasticsearch-6.8.23/plugins/ik elasticsearch-analysis-ik-6.8.23.zip
# Get into config Catalog 
vim elasticsearch.yml

Set cluster name , Data and log storage location ：

modify jvm Set up , You can set the occupied space according to the memory size

vim jvm.options

ElasticSearch Don't allow root User start , You need to create a user , And start with this user

groupadd nowcoder
useradd nowcoder1 -p  Set the password  -g nowcoder
cd /opt
chown -R nowcoder1:nowcoder *
cd /tmp
chown -R nowcoder1:nowcoder *
su - nowcoder1
# Get into elasticsearch After installing the directory , Background start ES
bin/elasticsearch -d
su
# Test for successful installation 
curl -X GET "localhost:9200/_cat/health?v"

Wkhtmltopdf

cd /
yum list wkhtmlyopdf*
yum install -y wkhtmltopdf.x86_64

need gui Support , Install virtual gui Program

yum install -y xorg-x11-server-Xvfb.x86_64
# test 
xvfb-run --server-args="-screen 0, 1024x768x24" wkhtmltoimage https://www.baidu.com 1.png

It is troublesome to write commands like this every time , So you can pack it

cd /opt
vim wkhtmltoimage.sh
# add to 
xvfb-run --server-args="-screen 0, 1024x768x24" wkhtmltoimage "[email protected]"
chmod +x wkhtmltoimage.sh
cd /test

echo $PATH

start-up tomcat

startup.sh

install nginx

yum list nginx*
yum install -y nginx.x86_64
vim /etc/nginx/nginx.conf

Comment out this paragraph

Add at the end of this paragraph ：

upstream myserver {
    
        server 127.0.0.1:8080 max_fails=3 fail_timeout=30s;
}

server {
    
        listen 80;
        server_name 49.232.164.108;
        location / {
    
                proxy_pass http://myserver;
        }
}

start-up nginx

systemctl start nginx

Deployment code

Because the root path is not processed , Therefore access / Be equivalent to accessing /index, One way is to access / Redirect to /index, Another way
You can put webapps Delete all in , Add your own projects .
Adjust the code ：
1、 stay application.properties Zhongba /community Change to empty .

2、 stay global.js Zhongba /community Change to empty

3、 stay HomeController Medium plus

@RequestMapping(path = "/", method = RequestMethod.GET)
public String root(){
    
    return "forward:/index";
}

4、 stay pom.xml Modify the packaging method and packaging name in


5、 By setting , Choose which profile to use , And modify the corresponding items

Change to server ip

6、tomcat It has main function , One Java There can't be two programs main function , So rewrite the method
The reconstruction CommunityServletInitializer class , Inherit SpringBootServletInitializer, Rewriting methods ：

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
    
    return builder.sources(CommunityApplication.class);
}

tomcat Access... From this class .
Use maven Of clean hold target Delete , And transfer the entire project file to the ECS .

unzip -d /test community.zip
# First download maven And perform packaging , Will download related dependencies , It will take some time 
# Get into community Medium pack 
mvn package -Dmaven.test.skip=true

If an error is reported ：[ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

yum install java-devel

Copy it to tomcat in ：

mv ROOT.war /opt/apache-tomcat-9.0.64/webapps/

linux Case sensitive , Log on first MySQL database

show variables like '%case%';

vim /etc/my.cnf
# add 
lower_case_table_names=1
# restart 
service mysqld restart

This for mysql8 no way . Manually change the table name to upper case .
