3.Tips
kingshard采用的是yaml方式解析配置文件，需要注意的是yaml配置文件不允许出现tab键，且冒号后面需要跟一个空格。配置文件编写完成后，可以在yaml lint网站验证是否有格式错误。
配置Kingshard
修改/etc/hosts文件, 添加如下二行
| 127.0.0.1 node1 127.0.0.1 node2 |
配置如下
| # server listen addr addr : 127.0.0.1:9696 # server user and password user : kingshard password : kingshard # log level[debug|info|warn|error],default error log_level : debug # only allow this ip list ip to connect kingshard #allow_ips: 127.0.0.1 # node is an agenda for real remote mysql server. nodes : - name : node1 # default max idle conns for mysql server idle_conns : 16 # if rw_split is true, select will use slave server rw_split: true # all mysql in a node must have the same user and password user : root password : root # master represents a real mysql master server master : 127.0.0.1:3307 # slave represents a real mysql salve server,and the number after '@' is #read load weight of this slave. #slave : 192.168.0.11:3307@2,192.168.0.12:3307@5 slave : #down_after_noalive : 300 - name : node2 # default max idle conns for mysql server idle_conns : 16 # if rw_split is true, select will use slave server rw_split: true # all mysql in a node must have the same user and password user : root password : root # master represents a real mysql master server master : 127.0.0.1:3308 # slave represents a real mysql salve server slave : # down mysql after N seconds noalive # 0 will no down down_after_noalive: 100 # schema defines which db can be used by client and this db's sql will be executed in which nodes schemas : - db : kingshard nodes: [node1,node2] rules: default: node1 shard: - table: test_shard_hash key: id nodes: [node1, node2] type: hash locations: [4,4] - table: test_shard_range key: id type: range nodes: [node1, node2] locations: [4,4] table_row_limit: 10000 |
设置mysql实例信息
设置用户
分类登陆mysqld2, mysqld3, 创建root用户(该用户是给kingshard管理的，测试为了方便所以直接使用root) 若用户存在，跳过此步
| /usr/bin/mysqladmin -h 127.0.0.1 -P 3307 -u root password 'root' /usr/bin/mysqladmin -h 127.0.0.1 -P 3308 -u root password 'root' |
建数据库
分类登陆mysqld2, mysqld2，创建kingshard数据库
| /usr/bin/mysql -h 127.0.0.1 -P 3307 -u root -proot -e "create database kingshard;" /usr/bin/mysql -h 127.0.0.1 -P 3308 -u root -proot -e "create database kingshard;" |
启动Kingshard
