二.Consul集群+Swarm集群部署微服务实战
1.在多台服务器上部署consul
(1).linux上面部署consul集群
2.通过docker部署搭建Consul集群

3.通过docker swarm搭建微服务集群
(1).准备mysql 以及 redis相关数据库
docker run --name myMysql -p 3306:3306 -v
/root/mysql/conf.d:/etc/mysql/conf.d -v /root/mysql/data:/var/lib/mysql -e
MYSQL_ROOT_PASSWORD=123456 -d mysqldocker run \
-p 6379:6379 \
--name redis \
-v /docker/redis/redis.conf:/etc/redis/redis.conf \
-v /docker/redis/data:/data \
--restart=always \
-d redis redis-server /etc/redis/redis.confdocker run \
-p 6379:6379 \ docker与宿主机的端口映射
--name redis \ redis容器的名字
-v /docker/redis/redis.conf:/etc/redis/redis.conf \ 挂载redis.conf文件
-v /docker/redis/data:/data \ 挂在redis的持久化数据
--restart=always \ 设置redis容器随docker启动而自启动
-d redis redis-server /etc/redis/redis.conf \ 指定redis在docker中的配置文件路径，后
台启动redis(2).准备程序
1).打包项目
2).对打包好的文件进行压缩
3).配置Dockerfile
微服务captcha
FROM centos:centos7
ADD /wwwroot/captcha.tar.gz /root
WORKDIR /root
RUN chmod -R 777 captcha
WORKDIR /root/captcha
ENTRYPOINT ["./captcha"]
微服务rbac
FROM centos:centos7
ADD /wwwroot/rbac.tar.gz /root
WORKDIR /root
RUN chmod -R 777 rbac
WORKDIR /root/rbac
ENTRYPOINT ["./rbac"]ginshop
FROM centos:centos7
ADD /wwwroot/ginshop.tar.gz /root
WORKDIR /root
RUN chmod -R 777 ginshop
WORKDIR /root/ginshop
ENTRYPOINT ["./ginshop"]
4).在要部署的服务器上面build对应的镜像
docker build -f captcha_Dockerfile -t docker.io/captchamicro:latest .
docker build -f rbac_Dockerfile -t docker.io/rbacmicro:latest .
docker build -f ginshop_Dockerfile -t docker.io/ginshop:latest .
(3).配置docker-compose.yml
version: "3"
services:
redis: #配置redis,这里可以单独配置redis,把redis放到专门的一台服务器上
image: redis
restart: always
deploy:
replicas: 1 #副本数量
captcha_micro: #验证码微服务
image: captchamicro #镜像名称:通过项目打包并build成的验证码微服务镜像
restart: always
deploy:
replicas: 6 #副本数量
resources: #资源
limits: #配置cpu
cpus: "0.3" # 设置该容器最多只能使用 30% 的 CPU
memory: 500M # 设置该容器最多只能使用 500M内存
restart_policy: #定义容器重启策略, 用于代替 restart 参数
condition: on-failure #只有当容器内部应用程序出现问题才会重启
rbac_micro: #rbac微服务
image: rbacmicro
restart: always
deploy:
replicas: 6 #副本数量
resources: #资源
limits: #配置cpu
cpus: "0.3" # 设置该容器最多只能使用 30% 的 CPU
memory: 500M # 设置该容器最多只能使用 500M内存
restart_policy: #定义容器重启策略, 用于代替 restart 参数
condition: on-failure #只有当容器内部应用程序出现问题才会重启
depends_on:
- captcha_micro
ginshop: #客户端微服务
image: ginshop
restart: always
ports:
- 8080:8080
deploy:
replicas: 6 #副本数量
resources: #资源
limits: #配置cpu
cpus: "0.3" # 设置该容器最多只能使用 30% 的 CPU
memory: 500M # 设置该容器最多只能使用 500M内存
restart_policy: #定义容器重启策略, 用于代替 restart 参数
condition: on-failure #只有当容器内部应用程序出现问题才会重启
depends_on:
- rbac_micro
(4).创建集群、部署微服务集群
#在192.168.31.129上面部署集群,命令如下:
docker swarm init --advertise-addr 192.168.31.129[root@manager_129 ~]# docker swarm init --advertise-addr 192.168.31.129
Swarm initialized: current node (qu1ydd2t6occ8fo76rvaksidd) is now a manager.
To add a worker to this swarm, run the following command:
docker swarm join --token SWMTKN-1-6afkz1ub7m8q37cehxmjiirs6a0r25qt1hzf0no1c0xcny55qc-d3gtv0qcsuhivozbomp4d73ha 192.168.31.129:2377
To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.
[root@manager_1291 ~](5).部署项目
(6).访问项目
(7).配nginx负载均衡
