交付apollo-configservice¶
准备软件包¶
准备apollo软件包
安装部署数据库¶
部署到10.4.7.10服务器上,这里使用的是mariadb,版本要在5.6版本以上,使用mysql同理
配置yum源¶
# vi /etc/yum.repos.d/MariaDB.repo
[mariadb]
name = MariaDB
baseurl = https://mirrors.ustc.edu.cn/mariadb/yum/10.1/centos7-amd64/
gpgkey=https://mirrors.ustc.edu.cn/mariadb/yum/RPM-GPG-KEY-MariaDB
gpgcheck=1
# rpm --import https://mirrors.ustc.edu.cn/mariadb/yum/RPM-GPG-KEY-MariaDB
安装MariaDB¶
# yum install MariaDB-server -y
配置MariaDB¶
# vim /etc/my.cnf.d/server.cnf
[mysqld]
character_set_server = utf8mb4
collation_server = utf8mb4_general_ci
init_connect = "SET NAMES 'utf8mb4'"
# vi /etc/my.cnf.d/mysql-clients.cnf
[mysql]
default-character-set = utf8mb4
启动数据库¶
# systemctl start mariadb
# systemctl enable mariadb
数据库初始化设置¶
设置密码¶
# mysqladmin -u root password
检查字符集¶
# mysql -uroot -p
> \s
注意字符集要是utf8mb4
执行数据库初始化脚本¶
主要是导入apolloconfig的数据库
下载数据库脚本
# wget https://raw.githubusercontent.com/ctripcorp/apollo/1.5.1/scripts/db/migration/configdb/V1.0.0__initialization.sql -O apolloconfig.sql
执行初始化脚本
# mysql -uroot -p < apolloconfig.sql
给数据库授权¶
数据库操作
> grant INSERT,DELETE,UPDATE,SELECT on ApolloConfigDB.* to 'apolloconfig'@'10.10.10.%' identified by "123456";
修改初始数据¶
数据库操作
> update ApolloConfigDB.ServerConfig set ServerConfig.Value="http://config.zs.com/eureka" where ServerConfig.Key="eureka.service.url";
配置域名解析¶
添加config域名和mysql域名解析,
config解析地址为10.4.7.20
mysql解析地址为10.4.7.10
# vi /var/named/zs.com.zone
# systemctl restart named
# dig -t A config.zs.com @10.4.7.10 +short
# dig -t A mysql.zs.com @10.4.7.10 +short
准备Docker镜像¶
此步骤在运维主机上进行操作
下载软件包¶
# wget https://github.com/ctripcorp/apollo/releases/download/v1.5.1/apollo-configservice-1.5.1-github.zip
解压软件包¶
# # mkdir /data/dockerfile/apollo-configservice
# unzip -o apollo-configservice-1.5.1-github.zip -d /data/dockerfile/apollo-configservice/
修改相关配置¶
修改数据库连接地址¶
# cd /data/dockerfile/apollo-configservice/
# vi application-github.properties
修改mysql的连接地址为:mysql.zs.com:3306
username = apolloconfig
password = 123456
如果不想使用域名,可以直接使用10.4.7.10宿主机的域名
修改启动脚本¶
/data/dockerfile/apollo-configservice/script/start.sh
注意 APOLLO_CONFIG_SERVICE_NAME=$(hostname -i) 这一行是我们自己增加的
#!/bin/bash
APOLLO_CONFIG_SERVICE_NAME=$(hostname -i)

## Adjust log dir if necessary
LOG_DIR=/opt/logs/apollo-config-server
