接上次继续 安装。

安装的protobuf可能版本不对，我换成了3.9.1版本。然后进行覆盖。

重复一遍，安装成功。

出现这样就是编译成功。

5.ip 设置

1.在anna包下安装，创建一个conf文件夹，conf/下创建proxy、server、user文件夹。

2.根据说明，创建相应名字的txt文件。单击情况，所有的ip都是本机的ip。ubuntu上查看用ifconfig 命令

For each server node:

1. The ip of the current node should be stored in conf/server/server_ip.txt.
2. The ip of the seed node should be stored in conf/server/seed_server.txt. The seed node can be any proxy node.
3. The ip of all the proxy nodes should be stored in conf/server/proxy_address.txt. Each line contains a single proxy ip.

For each proxy node:

1. The ip of the current node should be stored in conf/proxy/proxy_ip.txt.

For each user/benchmark node:

1. The ip of the current node should be stored in conf/user/user_ip.txt.
2. The ip of all the proxy nodes should be stored in conf/user/proxy_address.txt. Each line contains a single proxy ip.

6.运行

说明一点，模拟分布式环境。每个服务都需要有一份代码。

所以创建3个文件夹，anna_proxy、 anna_server、anna_user 里面代码包含全部的anna代码。

执行：

Please start the proxy first, and then the server and client.

1. Start a proxy by running ./build/kvs/kvs_proxy.
2. Start a server by running ./build/kvs/kvs_server.
3. Start a client by running ./build/kvs/kvs_user.

The accepted input formats are GET $key and PUT $key $value.
