部署Codis集群

启动zookeeper服务

配置 zookeeper

代码语言：javascript复制

[root@h101 zookeeper-Standalone]# grep -v "^#" conf/zoo.cfg 
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/tmp/zookeeper
dataLogDir=/tmp/zookeeper
clientPort=2180
[root@h101 zookeeper-Standalone]# 

启动 zookeeper

代码语言：javascript复制

[root@h101 zookeeper-Standalone]# bin/zkServer.sh start 
JMX enabled by default
Using config: /root/zk/zookeeper-Standalone/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@h101 zookeeper-Standalone]#

检查 zookeeper 状态

代码语言：javascript复制

[root@h101 zookeeper-Standalone]# cat /tmp/zookeeper/zookeeper_server.pid

Note: 不事先启动zk 而启动后面的服务会报错

启动codis dashboard

配置 config.ini

Note: codis-config 和 codis-proxy 在不加 -c 参数的时候, 默认会读取当前目录下的 config.ini 文件

代码语言：javascript复制

[root@h102 codis]# grep -v "^#" config.ini  | grep -v "^$"
coordinator=zookeeper
zk=192.168.100.101:2180
product=test
dashboard_addr=192.168.100.102:18087
password=codis
backend_ping_period=5
session_max_timeout=1800
session_max_bufsize=131072
session_max_pipeline=1024
zk_session_timeout=30000
proxy_id=proxy_1
[root@h102 codis]#
