2.nacos-v1.x.x

若依版本3.x.x 以下安装此nacos

1.docker

docker  run \
--name nacos -d \
-p 9848:8848 \
--privileged=true \
--restart=always \
-e JVM_XMS=256m \
-e JVM_XMX=256m \

-v /mydata/nacos/logs:/home/nacos/logs \
-v /mydata/nacos/conf:/home/nacos/conf \
-v /mydata/nacos/init.d/custom.properties:/home/nacos/init.d/custom.properties \
nacos/nacos-server

2.custom.properties

server.contextPath=/nacos
server.servlet.contextPath=/nacos
server.port=8848

spring.datasource.platform=mysql
#这里的数据库连接信息更改成我们前面准备好的nacos数据库
db.num=1
db.url.0=jdbc:mysql://192.168.0.23:3306/ry_config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true

nacos.naming.distro.initDataRatio=0.9
nacos.naming.distro.syncRetryDelay=5000
nacos.naming.data.warmup=true
nacos.naming.expireInstance=true

2. mysql

1.dockerr

docker run -p 3306:3306 --name mysql \
-v /mydata/mysql/log:/var/log/mysql \
-v /mydata/mysql/data:/var/lib/mysql \
-v /mydata/mysql/conf:/etc/mysql \
-e MYSQL_ROOT_PASSWORD=root \
-d mysql:5.7

2. 配置

创建mysql配置文件，在/docker/mysql/conf下my.cnf

# 在/docker/mysql/conf下my.cnf
touch my.cnf
# 添加配置
vim /docker/mysql/conf/my.cnf
[client]
default-character-set=utf8

[mysql]
default-character-set=utf8

[mysqld]
init_connect='SET collation_connection = utf8_unicode_ci'
init_connect='SET collation_connection = utf8_unicode_ci'
init_connect='SET NAMES utf8'
character-set-server=utf8
collation-server=utf8_unicode_ci
skip-character-set-client-handshake
skip-name-resolve

# 重启mysql容器
docker restart mysql

3.redis

1.docker

docker run --restart=always -p 6379:6379 --name redis \
 -v /docker/redis/data:/data \
 -v /docker/redis/conf/redis.conf:/etc/redis/redis.conf \
 -d redis redis-server /etc/redis/redis.conf \
 --appendonly yes --requirepass redis

注：

docker logs --since 30m redis
----------------------------
WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.

编辑主机的/etc/sysctl.conf文件，添加或者配置，保存

vm.overcommit_memory = 1

重启Redis服务即可

4.sentinel

spring: 
  cloud:
    sentinel:
      transport:
        dashboard: 192.168.0.23:8718
      web-context-unify: false # 关闭context整合
feign:
  sentinel:
    enabled: true # 开启feign对sentinel的支持

1）下载

sentinel官方提供了UI控制台，方便我们对系统做限流设置。大家可以在GitHub下载。

2）如果要修改Sentinel的默认端口、账户、密码，可以通过下列配置：

配置项	默认值	说明
server.port	8080	服务端口
sentinel.dashboard.auth.username	sentinel	默认用户名
sentinel.dashboard.auth.password	sentinel	默认密码

例如，修改端口：

java -Dserver.port=8090 -jar sentinel-dashboard-1.8.1.jar

5.其他

1.其他

# 1.修改每个bootstrap.yml的IP和端口
# 2.导入数据
# 3.启动nacos修改配置文件中的IP和端口
# 4.前端页面的sentinel和nacos在前端的菜单设置里面修改
# 5.sentinel整合，所需的微服务里添加sentinel配置
