修改此值

[root@h102 codis]# extern/redis-2.8.21/src/redis-cli -p 6379 CONFIG set maxmemory 100
OK
[root@h102 codis]# extern/redis-2.8.21/src/redis-cli -p 6389 CONFIG set maxmemory 100
OK
[root@h102 codis]# extern/redis-2.8.21/src/redis-cli -p 6390 CONFIG set maxmemory 100
OK
[root@h102 codis]# extern/redis-2.8.21/src/redis-cli -p 6380 CONFIG set maxmemory 100

[root@h102 codis]# extern/redis-2.8.21/src/redis-cli -p 6379 CONFIG GET maxmemory
1) "maxmemory"
2) "100"
[root@h102 codis]# extern/redis-2.8.21/src/redis-cli -p 6380 CONFIG GET maxmemory
1) "maxmemory"
2) "100"
[root@h102 codis]# extern/redis-2.8.21/src/redis-cli -p 6389 CONFIG GET maxmemory

[root@h102 codis]#

进行自动均衡

[root@h102 codis]# bin/codis-config slot rebalance 
{
  "msg": "OK",
  "ret": 0
}
[root@h102 codis]#

codis dashboard重启问题

codis dashboard由于各种原因可能要重启

比如重读配置文件(将zk端口从2180改为2181)，此时dashboard会报错

2015/12/04 22:38:08 Failed to connect to 192.168.100.101:2180: dial tcp 192.168.100.101:2180: i/o timeout
2015/12/04 22:38:09 Failed to connect to 192.168.100.101:2180: dial tcp 192.168.100.101:2180: i/o timeout

2015/12/04 22:38:09 Failed to connect to 192.168.100.101:2180: dial tcp 192.168.100.101:2180: i/o timeout

另开一个窗口，手动将dashboard进程杀死

[root@h102 codis]# kill  36106
