准备机器3台
- 192.168.1.160
- 192.168.1.161
- 192.168.1.162
docker安装
CentOS 7下安装Docker及基础操作
安装
mysql
- 基于docker安装mysql
docker run
-p 3306:3306
--name nacos-mysql
-v $PWD/conf:/etc/mysql/conf.d
-v $PWD/logs:/logs
-v $PWD/data:/var/lib/mysql
-v /etc/localtime:/etc/localtime:ro
-e TZ=Asia/Shanghai
-e MYSQL_ROOT_PASSWORD=root
-d mysql:5.7- 初始化sql sql脚本入口:https://github.com/alibaba/nacos/blob/master/distribution/conf/nacos-mysql.sql
Nacos
- 创建Nacos的工作目录
// 每个节点都创建
mkdir -p /usr/local/docker/nacos-server
mkdir -p /usr/local/docker/nacos-server/env
mkdir -p /usr/local/docker/nacos-server/logs
mkdir -p /usr/local/docker/nacos-server/init.d- 调整custom.properties
vim /usr/local/docker/nacos-server/init.d/custom.properties
// 添加以下配置
#spring.security.enabled=false
#management.security=false
#security.basic.enabled=false
#nacos.security.ignore.urls=/**
#management.metrics.export.elastic.host=http://localhost:9200
# metrics for prometheus
management.endpoints.web.exposure.include=*
# metrics for elastic search
#management.metrics.export.elastic.enabled=false
#management.metrics.export.elastic.host=http://localhost:9200
# metrics for influx
#management.metrics.export.influx.enabled=false
#management.metrics.export.influx.db=springboot
#management.metrics.export.influx.uri=http://localhost:8086
#management.metrics.export.influx.auto-create-db=true
#management.metrics.export.influx.consistency=one
#management.metrics.export.influx.compressed=true- 调整nacos-hostname.env
vim /usr/local/docker/nacos-server/env/nacos-hostname.env
#nacos dev env
# 首选主机模式
PREFER_HOST_MODE=hostname
# 当前主机的IP
NACOS_SERVER_IP=192.168.1.160
# 集群的各个节点
NACOS_SERVERS=192.168.1.160:8848 192.168.1.161:8848 192.168.1.162:8848
# 数据库的配置
MYSQL_SERVICE_HOST=192.168.1.100
MYSQL_SERVICE_DB_NAME=nacos
MYSQL_SERVICE_PORT=3306
MYSQL_SERVICE_USER=root
MYSQL_SERVICE_PASSWORD=root
# 从节点 这里就使用单节点测试,因此就不配置从节点
#MYSQL_SLAVE_SERVICE_HOST=xxx
#MYSQL_SLAVE_SERVICE_PORT=3306
# JVM参数 默认是2G 如果使用虚拟机,内存没有2G,就需要调整这里的参数,否则将无法启动
JVM_XMS=256m
JVM_XMX=256m
JVM_XMN=256m- 将配置文件拷贝到其他两台机器
scp -r /usr/local/docker/nacos-server/env/nacos-hostname.env root@192.168.1.:/usr/local/docker/nacos-server/env/nacos-hostname.env
scp -r /usr/local/docker/nacos-server/env/nacos-hostname.env root@192.168.1.:/usr/local/docker/nacos-server/env/nacos-hostname.env
scp -r /usr/local/docker/nacos-server/init.d/custom.properties root@192.168.1.:/usr/local/docker/nacos-server/init.d/custom.properties
scp -r /usr/local/docker/nacos-server/init.d/custom.properties root@192.168.1.:/usr/local/docker/nacos-server/init.d/custom.properties- docker启动(3个节点)
docker run
-p :
--restart=always
--name nacos-node
--env-file=/usr/local/docker/nacos-server/env/nacos-hostname.env
-v /usr/local/docker/nacos-server/logs:/home/nacos/logs
-v /usr/local/docker/nacos-server/init.d/custom.properties:/home/nacos/init.d/custom.properties
-d nacos/nacos-server
- 异常查看
// 如果出现异常,可以在/usr/local/docker/nacos-server/logs目录下查看
tail -f /usr/local/docker/nacos-server/logs/nacos.log测试
访问任意节点的8848端口; 如: 192.168.1.160:8848/nacos 默认用户名和密码为: nacos/nacos ;登录之后查看节点即可看到如下效果.
当停用任何一个节点,都不会影响正常的使用
Nginx代理Nacos集群
- 创建nacos.conf；添加以下配置
upstream nacos_server {
server 192.168.1.160:8848;
server 192.168.1.161:8848;
server 192.168.1.162:8848;
}
server {
listen ;
listen ssl;
#填写绑定证书的域名
server_name nacos.你的域名;
#ssl on;
ssl_certificate /你的证书路径.crt;
ssl_certificate_key /你的密钥路径.key;
ssl_session_timeout 5m;
#按照这个协议配置
ssl_protocols TLSv1 TLSv1. TLSv1.;
#按照这个套件配置
ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE;
ssl_prefer_server_ciphers on;

}
}- 重启服务
sbin/nginx -t
sbin/nginx -s reload
