tcp reverse proxy tutorial

scenario

• execute zookeeper(example process which is publishing tcp port)
• execute nginx for reverse proxing
• connect zk through nginx

execute zookeeper

bin $ pwd
/Users/yubi.lee/workspace/zk/zookeeper-3.4.11/bin

bin $ ls ../conf/
configuration.xsl log4j.properties  zoo.cfg           zoo_sample.cfg

bin $ cat ../conf/zoo.cfg
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=/tmp/zookeeper
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1

bin $ ./zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /Users/yubi.lee/workspace/zk/zookeeper-3.4.11/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

$ ./zkCli.sh -server localhost:2181
[zk: localhost:2181(CONNECTED) 0]

execute nginx

$ ./configure     --sbin-path=/Users/yubi.lee/workspace/nginx --prefix=/Users/yubi.lee/workspace/nginx --conf-path=/Users/yubi.lee/workspace/nginx/conf/nginx.conf --pid-path=/Users/yubi.lee/workspace/nginx/pid/nginx.pid --with-stream
$ ./make
$ ./objs/nginx

• nginx.conf

  events {
  worker_connections  1024;
  }
  stream {
  server {
  listen 8080;
  proxy_pass localhost:2181; // zookeeper
  }
  }

• zkCli.sh 로 접속 시도
  • 성공, localhost:8080 (nginx) -> localhost:2181 (zookeeper)

    $ ./zkCli.sh -server localhost:8080
    [zk: localhost:8080(CONNECTED) 0] ls /
    [zookeeper]
    [zk: localhost:8080(CONNECTED) 1] ls /
    [zookeeper]
    [zk: localhost:8080(CONNECTED) 2] ls /zookeeper
    [quota]
    [zk: localhost:8080(CONNECTED) 3] ls /zookeeper/quota
    []
