1. 环境
2. 拉取镜像、开放端口、创建自定义网络
3. MySQL 8.0
4. 创建数据库
5. nacos节点1
6. nacos节点2
7. nacos节点3
8. nginx01
9. 搭建结果
10. 客户端测试
11. 目前未解决的问题
Nacos集群部署
- CentOS 7
- MySQL 8.0
- Nacos Server 2.0.3
- Nginx 1.20
docker pull nacos/nacos-server:2.0.3
# 开放端口
firewall-cmd --add-port=7848-7854/tcp --zone=public --permanent
firewall-cmd --add-port=8848-8854/tcp --zone=public --permanent
firewall-cmd --add-port=9848-9854/tcp --zone=public --permanent
firewall-cmd --add-port=8080-8082/tcp --zone=public --permanent
firewall-cmd --reload
# 创建自定义网络
docker network create --driver bridge --subnet 172.18.0.0/16 --gateway 172.18.0.1 nacos-net
Nacos端口开放依据
3. MySQL 8.0
# 拉取镜像
docker pull mysql:8.0
# 在宿主机创建放置mysql的配置文件目录、数据目录和日志目录，并且进行授权
mkdir -p /mydata/mysql/{data,conf,log}
chmod -R 755 /mydata/mysql/
# 创建MySQL的配置文件
vim /mydata/mysql/conf/my.cnf
# 添加以下内容到上述创建的配置文件中
[client]
# socket = /mydata/mysql/mysqld.sock
# 修改字符编码
default-character-set = utf8mb4
[mysqld]
# pid-file = /var/run/mysqld/mysqld.pid
# socket = /var/run/mysqld/mysqld.sock
# datadir = /var/lib/mysql
# socket = /mydata/mysql/mysqld.sock
# pid-file = /mydata/mysql/mysqld.pid
datadir = /mydata/mysql/data
character_set_server = utf8mb4
collation_server = utf8mb4_bin
# 跳过域名检查，解决MySQL连接慢的问题
skip-name-resolve
secure-file-priv= NULL
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# Custom config should go here
!includedir /etc/mysql/conf.d/
# 创建并启动容器
docker run \
-v /mydata/mysql/log:/var/log/mysql \
-v /mydata/mysql/data:/var/lib/mysql \
-v /mydata/mysql/conf/my.cnf:/etc/mysql/my.conf \
-e TZ=Asia/Shanghai \
-e MYSQL_ROOT_PASSWORD=123456 \
-p 3306:3306 \
--restart=unless-stopped \
--net nacos-net \
--ip 172.18.100.1 \
--name mysql \
-d mysql:8.0
# 进入容器
docker exec -it mysql /bin/bash
# mysql远程登录设置
# 连接数据库;看到Enter password时，直接回车，否则会出现这样的错误Access denied for user 'root'@'localhost' (using password: YES)
mysql -uroot -p
# 使用数据库
use mysql
# 修改访问主机以及密码等，设置为所有主机可访问
# 查看是否运行远程访问；如果root用户的host为localhost，要远程访问，需要将它改成%
select host,user,plugin from user;
# 将host改为%
update user set host='%' where user ='root';
# 更改连接的密码校验方式（mysql_native_password，mysql8.x版本必须使用这种模式，否则navicate无法正确连接）
ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '新密码';
# 刷新权限
flush privileges;
4. 创建数据库
