Linux (CentOS) installation configuration zeromq, JZMQ (solve various problems)

Today for Hadoop configuration Zeromq, JZMQ encountered a variety of problems, first compile error, to compile a successful test error, and so on, the following I encountered the problem to share with you.

The first note is: You must compile and install ZEROMQ, and then compile JZMQ, otherwise you will be reported zmq.h file cannot be found.

Official installation Configuration link: Http://zeromq.org/bindings:java

Step 1: Install the necessary dependent packages:

sudo Yum Install GCC GCC  make Libuuid-dev git java-1.6. 0-openjdk-devel

Note: Some of these packages are different depending on the operating system, so it is not the name above, please use the Yum list avaiable *package name* to query the available packages and install them. For example: Look for OpenJDK, the blue background is what we are looking for.

Step 2: Compile and install zeromq-2.1.7

2.1 Unpacking the Package

tar -zxvf zeromq-2.1. 7. tar. gz

2.2 Build&&install

./autogen.sh. /Configuremakesudomakeinstall

Step 3: Compile and install JZMQ

3.1 Clone JZMQ from GitHub

$ git clone https://github.com/zeromq/jzmq.git

3.2 Bulid&&install (official offer steps, unfortunately not)

$ cd jzmq$. /autogen. SH $ . /make#在执行make的时候报 make[1]: *** No rule to make target `classdist_noinst.stamp‘, needed by `org/zeromq/ZMQ.class‘. Stop.   sudo make install 

3.3 Error Exclusions

1) Ensure that the Step 1 dependency pack is fully installed

2) Check that the JDK is not used openjdk6, if not please java_home temporarily point to/usr/lib/jvm/java-1.6.0-openjdk.x86_64/

Echo $JAVA _home/usr/java/jdk1. 6 . 0_45  ~]$ java_home=/usr/lib/jvm/java-1.6. 0-openjdk.x86_64/

3.4 Resolving errors

1) Switch the directory to JZMQ/SRC

2)touch classdist_noinst.stamp

3) Execution:

classpath=.:./.: $CLASSPATH javac-d. Org/zeromq/zmq.java Org/zeromq/zmqexception.java Org/zeromq/zmqqueue.java Org/zeromq/zmqforwarder.java org/zeromq/ Zmqstreamer.java

4)

CD ... /autogen. SH . /Configuremakesudomakeinstall

5) test whether the installation is successful, switch to the jzmq/perf/directory, execute sh local_lat.sh tcp://127.0.0.1:5000 1 to test:

[Email protected] jzmq]$ CD perf/[email protected] perf]$SHLocal_lat.SHTcp://127.0.0.1:5000 1ExceptioninchThread"Main"Java.lang.UnsatisfiedLinkError:no jzmq   in Java.library.path at Java.lang.ClassLoader.loadLibrary (Classloader.java:1738) at Java.lang.Runtime.loadLibrary0 (Runtime.java:823) at Java.lang.System.loadLibrary (System.java:1028) at Org.zeromq.ZMQ.<clinit> (Zmq.java: the) at Local_lat.main (Local_lat.java: $)

No jzmq in Java.library.path???

Workaround:

Export java_library_path=/usr/local/lib or export Ld_library_path=/usr/local/Lib It is best to join it ~/   VI ~/. BASHRC Export Ld_library_path=/usr/local/lib

Then in the test everything OK, first executed under a terminal:sh local_lat.sh tcp://127.0.0.1:5000 1

[[email protected] perf]$ source ~/sh local_lat.sh tcp://127.0.0.1:5000 1 100 

At this point, open another terminal execution:sh remote_lat.sh tcp://127.0.0.1:5000 1

[[Email protected] jzmq]$ CD perf/pwd/home/mdrill01/component/jzmq/sh remote_ Lat.sh tcp://127.0.0.1:5000 11  [B] # # # # #说明测试成功 10 0140.0
