Nacos installation and cluster construction under Linux

1. Nacos download and install

1. Download
   https://github.com/alibaba/nacos/releases/tag/1.1.4
2. Unzip

tar -zxvf nacos-server-1.1.4.tar.gz

3. Rewrite the nacos script
   in Linux and add it in nacos/config/application.properties

spring.datasource.platform=mysql

db.num=1
db.url.0=jdbc:mysql://127.0.0.1:3306/nacos_config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true
db.user=root
db.password=123456

4. Modify cluster.conf

hostname -I #查看可识别hostname
cp cluster.conf cluster.conf.init
vim cluster.conf
#在cluster.conf中添加
10.138.219.23:3333
10.138.219.23:4444
10.138.219.23:5555

5. Edit Nacos' startup script startup.sh to enable him to receive different startup ports

#nacos/bin
cp startup.sh.example startup.sh
vim startup.sh

6. Nginx configuration as a load balancer

firewall-cmd --list-all #查看开放的端口号
sudo firewall-cmd --add-port=80/tcp --permanent # 设置开放的端口号
firewall-cmd --reload #重启防火墙

Change setting

cd /usr/local/nginx/sbin
vim nginx.conf

upstream cluster{
    server 127.0.0.1:3333;
    server 127.0.0.1:4444;
    server 127.0.0.1:5555;
}
# 修改端口
server {
    listen       1111;
    server_name  localhost;

    #charset koi8-r;

    #access_log  logs/host.access.log  main;

    location / {
        #root   html;
        #index  index.html index.htm;
        proxy_pass http://cluster;
    }

start up

./nginx -c /usr/local/nginx/conf/nginx.conf

2 Nacos cluster construction

1. Start nacos

./startup.sh -p 3333
./startup.sh -p 4444
./startup.sh -p 5555

2. Check whether to start 3 nacos

ps -ef|grep nacos|grep -v grep|wc -l

3. Start nginx

./nginx -c /usr/local/nginx/conf/nginx.conf
#查看是否启动
ps -ef|grep nginx

nacos.inetutils.prefer-hostname-over-ip=false
4. 测试

1. 10.138.219.23:1111/nacos successfully visited

2. After the configuration is added successfully, the database inserts a piece of data
   

3. Modify the microservice configuration file

 spring:
     application:
         name: nacos-payment-provider
     cloud:
         nacos:
             discovery:
             #server-addr: localhost:8848
             server-addr: 10.138.219.23:1111

4. Start the microservice and register successfully
