环境

window10
虚拟机：VMware Pro 12 centos7 、ubuntu16.04
CRT: 8
mysql:5.6

准备工作

虚拟机要准备好，我准备了两个centos7和一个ubuntu 16.04 window10 中装好MySQL；

下载两个SQL：

apolloportaldb.sql

apolloconfigdb.sql

执行上面SQL，创建好表；

apolloportaldb库的验证语句：

select `Id`, `Key`, `Value`, `Comment` from `ApolloPortalDB`.`ServerConfig` limit 1;

ApolloConfigDB库的验证语句：

select `Id`, `Key`, `Value`, `Comment` from `ApolloConfigDB`.`ServerConfig` limit 1;

我的设备环境

一台centos7虚拟机：地址：192.168.116.133（部署dev环境的apolloconfig和apolloadmin）

一台ubuntu虚拟机：地址：192.168.116.134（部署apolloportaldb）

window10宿主机：地址：192.168.1.104 (装MySQL数据库）

下载安装包

也可以源码构建，但是目前我并不要二次改造，所以就直接下载安装包了

apollo-adminservice-1.5.1-github.zip apollo-configservice-1.5.1-github.zip apollo-portal-1.5.1-github.zip

最新版的地址：https://github.com/ctripcorp/apollo/releases

修改配置

下载了上面三个压缩包后，全部都解压；

修改apollo-configservice的配置

找到apollo-configservice-x.x.x-github/config/application-github.properties文件：

spring.datasource.url = jdbc:mysql://192.168.1.104:3306/ApolloConfigDB?useSSL=false&characterEncoding=utf8
spring.datasource.username = root
spring.datasource.password = root

因为我虚拟机上没有装mysql，所以我这里不能写localhost:3306,而是写window10主机的IP地址

修改apollo-adminservice的配置

找到apollo-adminservice-x.x.x-github/config/application-github.properties文件：

spring.datasource.url = jdbc:mysql://192.168.1.104:3306/ApolloConfigDB?useSSL=false&characterEncoding=utf8
spring.datasource.username = root
spring.datasource.password = root

修改apollo-portal的配置

找到将apollo-portal-x.x.x-github/config/apollo-env.properties文件：
目前我就部署dev环境

local.meta=http://localhost:8080
dev.meta=http://192.168.116.133:8080
# 假设还要部署fat环境
#fat.meta=http://192.168.116.135:8080

找到将apollo-portal-x.x.x-github/config/application-github.properties文件：

spring.datasource.url = jdbc:mysql://192.168.1.104:3306/ApolloConfigDB?useSSL=false&characterEncoding=utf8
spring.datasource.username = root
spring.datasource.password = root

修改MySQL数据库中数据

apolloconfigdb

找到serverconfig表中key：eureka.service.url，写eureka的地址；

又因为eureka和config目前的实现是和config是一个进程，所以只需要写config服务所在服务器的地址。

java apollo配置客户端实时获取_java

apolloportaldb

找到serverconfig表中key：apollo.portal.envs的数据

java apollo配置客户端实时获取_apollo_02

我这里只部署了dev，所以不用改，如果部署了dev、fat和uat等，那么就要以逗号分割接着后面写；

开启MySQL远程连接

随便打开一个查询，执行如下SQL：

# GRANT ALL PRIVILEGES ON *.* TO '账号'@'%' IDENTIFIED BY '密码';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root';

%代表所有主机，也可以具体到你的主机ip地址

window防火墙添加入站规则

因为虚拟机要远程访问window的数据库，得开放端口3306。

虚拟机开放8080和8090端口

因为apollopartaldb需要去连接apolloconfig，
所以apolloconfig所在的服务器，需要开放8080和8090端口

具体怎么开后门，根据自己的环境百度吧~

部署

再次打包成压缩包

window直接使用压缩软件进行压缩。

上传到虚拟机

可以使用rz命令进行上传。

再使用unzip进行解压

先启动apollo-configservice

我的路径：

/home/yutao/programefile/apollo/apollo-configservice-1.5.1-github/scripts

修改执行权：

sudo chmod 755 ./startup.sh
sudo chmod 755 ./shutdown.sh

然后执行：

[yutao@localhost scripts]$ ./startup.sh

提示
启动日志里面会报错误：

刚启动报这个错是正常的，因为config service要向eureka注册，但是eureka还没启动好（因为eureka和config service是同一个进程），过一会儿就OK了。

启动apollo-adminservice

和上面类似的步骤；
先修改执行权，再执行./startup.sh来启动。

启动apollo-portal

和上面类似的步骤；
