在Linux上部署Java访问MongoDB

1.环境

OS: CentOS 6.5 x64

MongoDB：3.2.7

Java：1.6

开发环境：win7 eclipse

2.写好java程序

3.部署

在CentOS 6.5安装好java 1.6，并配置好环境变量。

将写好的java程序编译好压缩成包：

我的singleI.class属于mongodb包所以在mongodb目录下，把mongodb目录打包压缩成mongodb.zip。

将mongodb.zip和mongo-java-driver-3.2.2.jar（mongodb的java驱动包）上传到CentOS，例如传到test目录下：

[mongodb@VM6-58 test]$ ls

mongodb.zip  mongo-java-driver-3.2.2.jar

[mongodb@VM6-58 test]$ cd 

[mongodb@VM6-58 ~]$ vi .bash_profile     #配置环境变量

在最追加

CLASSPATH=/home/mongodb/test/mongodb.zip:/home/mongodb/test/mongo-java-driver-3.2.2.jar:$CLASSPATH

export CLASSPATH

[mongodb@VM6-58 ~]$ source .bash_profile 

[mongodb@VM6-58 ~]$ echo $CLASSPATH

/home/mongodb/test/mongodb.zip:/home/mongodb/test/mongo-java-driver-3.2.2.jar:.:/opt/web_app/jdk/lib/dt.jar:/opt/web_app/jdk/lib/tools.jar:/opt/web_app/jdk/jre/lib:     #dt.jar tool.jar也不能少

4.运行

[mongodb@VM6-58 ~]$ java mongodb.singleI
