• kingshard地址

安装kingshard

1. 安装Go语言环境（请使用最新版），具体步骤请Google。
    2. git clone https://github.com/flike/kingshard.git $GOPATH/src/github.com/flike/kingshard
    3. cd src/github.com/flike/kingshard
    4. source ./dev.sh
    5. make
    6. 设置配置文件
    7. 运行kingshard。./bin/kingshard -config=etc/ks.yaml

修改kingshard/etc/unshard.yaml配置，修改master和slave和log_path

# node is an agenda for real remote mysql server.
nodes :
-
    name : node1

    # default max conns for mysql server
    max_conns_limit : 32

    # all mysql in a node must have the same user and password
    user :  root
    password : kingshard

    # master represents a real mysql master server
    master : 127.0.0.1:3307 # 主

    # slave represents a real mysql salve server,and the number after '@' is
    # read load weight of this slave.
    slave : 127.0.0.1:3308 # 主
    #down_after_noalive : 32

运行kingshard

mysql -h127.0.0.1 -ukingshard -pkingshard -P9696;

执行sql，查看log,已实现读写分离

➜  log git:(master) ✗ tail -f sql.log
