最全CacheCloud最完整安装使用文档【实操系列】

准备阶段

1. 下载 cachecloud-master版本

解压后目录

cachecloud-master# ll -h
total 56K
drwxr-xr-x 6 root root 4.0K Nov 14 16:41 cachecloud-open-client
drwxr-xr-x 3 root root 4.0K Nov 14 16:41 cachecloud-open-common
drwxr-xr-x 4 root root 4.0K Nov 14 16:41 cachecloud-open-web
-rw-r--r-- 1 root root  12K Nov 14 16:41 LICENSE
-rw-r--r-- 1 root root  13K Nov 14 16:41 pom.xml
-rw-r--r-- 1 root root 8.7K Nov 14 16:41 README.md
drwxr-xr-x 2 root root 4.0K Nov 14 16:41 script

2. 安装mysql

   略

3. 导入项目中cachecloud.sql初始化库表结构，默认插入admin超级管理员。

安装cachecloud

直接按照生产环境标准安装

• 在cachecloud根目录下运行

root@xxxx # mvn clean compile install -Ponline

运气真好，果然报错了（网上其他文章基本上都是直接跳过此步骤。也是醉了）

解决方法，在软件根目录下/pom.xml 中http://repo1.maven.org/maven2

原配置：   	http://repo1.maven.org/maven2
修改配置：   https://repo1.maven.org/maven2

再次执行

root@xxxx # mvn clean compile install -Ponline
...
就不贴输出了
...

• 拷贝war包(cachecloud-open-web/target/cachecloud-open-web-1.0-SNAPSHOT.war)到/opt/cachecloud-web下
• 拷贝配置文件(cachecloud-open-web/src/main/resources/cachecloud-web.conf)到/opt/cachecloud-web下，并改名为cachecloud-open-web-1.0-SNAPSHOT.conf（spring-boot要求，否则配置不生效）

注意了，此处网上文章又说的比较粗糙，以下是diff出来的差异，当然要根据实际生产情况适当修改

root@xxxx cachecloud# diff cachecloud-open-web/src/main/resources/cachecloud-web.conf /opt/cachecloud-web/cachecloud-open-web-1.0-SNAPSHOT.conf

• 启动，我是选择使用启动脚本，当然也是要根据环境适当修改，主要是配置部分

...
SERVER_NAME=root
DEPLOY_DIR=/opt/cachecloud-web
STDOUT_FILE=${DEPLOY_DIR}/logs/cachecloud-web.log
WAR_FILE=${DEPLOY_DIR}/cachecloud-open-web-1.0-SNAPSHOT.war
...

登陆

• 访问http://127.0.0.1:9999/manage/login

右上角：（记得修改）

admin --> 管理后台 --> 系统配置关系 --> 机器ssh密码(一定要修改)

• 初始化物理机（记得密码要与上部一致哦～）

root@xxxx # cat cachecloud-init.sh
...
readonly redisDir="/opt/cachecloud/redis" # 部署位置，根据需要调整即可
readonly redisTarGz="redis-3.0.7.tar.gz"  # 版本信息，根据需要调整即可
...

• 物理集群管理

admin --> 管理后台 --> 机器管理

成功后将会有真实的系统资源展示

特别提醒，最好使用master版本，因为可以迁移slot

• 数据迁移工具

使用的是redis-migrate-tool，需要先下载。

注意，不能3.x版本迁移到4.x
