配置中心Apollo安装

简介

Apollo（阿波罗）是携程框架部门研发的分布式配置中心，能够集中化管理应用不同环境、不同集群的配置，配置修改后能够实时推送到应用端，并且具备规范的权限、流程治理等特性，适用于微服务配置管理场景。

• apollo-configservice：提供配置获取接口，提供配置更新推送接口，接口服务对象为Apollo客户端
• apollo-adminservice：提供配置管理接口，提供配置修改、发布等接口，接口服务对象为Portal，以及Eureka
• apollo-portal：提供Web界面供用户管理配置
• apollo-client：Apollo提供的客户端程序，为应用提供配置获取、实时更新等功能

 

上图简要描述了配置发布的大致过程：

• 用户在Portal操作配置发布
• Portal调用Admin Service的接口操作发布
• Admin Service发布配置后，发送ReleaseMessage给各个Config Service

• Config Service收到ReleaseMessage后，通知对应的客户端

 

安装部署

docker安装

#关闭防火墙
systemctl stop firewalld.service
systemctl disable firewalld.service
firewall-cmd --state
#关闭selinux
sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config && setenforce 0
#安装docker
yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum install docker-ce-19.03.5 -y
#启动docker并设置开机自启
systemctl start docker && systemctl enable docker
#docker-compose编排工具安装方式
curl -L https://get.daocloud.io/docker/compose/releases/download/1.25.1/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose && ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose 
#查看版本
docker version && docker-compose --version
#设置容器镜像加速器
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://zx28up8j.mirror.aliyuncs.com"]
}
EOF
#重载配置并重启docker
systemctl daemon-reload && systemctl restart docker

apollo安装

cd /usr/local/src
git clone -b 1.5.1 https://github.com/ctripcorp/apollo.git 或者 wget https://github.com/ctripcorp/apollo/archive/v1.5.1.tar.gz #解压后更改目录名为apollo
mkdir -p apollo-adminservice apollo-portal apollo-configservice portal-sql config-sql
cp apollo/scripts/docker-quick-start/sql/apolloconfigdb.sql config-sql/
cp apollo/scripts/docker-quick-start/sql/apolloportaldb.sql portal-sql/
#防止容器ip注册到Eureka的方案有：
#方案一:把docker0和veth.*的网卡在注册到Eureka时忽略掉（用此方案就行）
sed -i '/active:/a\  cloud:\
    inetutils:\
      ignoredInterfaces:\
        - docker0\
        - veth.*' apollo/{apollo-adminservice,apollo-configservice}/src/main/resources/application.yml
#方案二：强制指定admin server和config server向eureka注册的IP
#sed -i '/instance:/a\    ip-address: ${eurekaip-address}' apollo/{apollo-adminservice,apollo-configservice}/src/main/resources/bootstrap.yml
#更多方案，查看https://github.com/ctripcorp/apollo/wiki/部署&开发遇到的常见问题

启动容器

docker-compose build && docker-compose up -d #启动编排文件里面的容器

 

 

docker-compose ps #查看容器启动情况

 

 

#日志文件路径
/opt/logs/
#由于configservice容器自带了eureka服务，把服务注册地址修改为物理机所映射的端口，也就是8080，执行
docker exec -it config-db mysql -u root -pDoordu -D ApolloConfigDB -e "update ServerConfig set Value = 'http://本机IP:8080/eureka/' where id = 1;"

#针对不同环境修改权限，登录控制端数据库，经测试填入pro则屏蔽pro环境的配置，忽略掉官方备注！o(∩_∩)o
