mongodb3.2二进制单机版安装
1.环境介绍2.配置环境变量,修改与之相关的系统参数3.创建mongodb运行用户和目录等4.上传安装包，解压安装5.创建配置文件6.启动并进行简单测试7.总结1.环境介绍：OS:Centos6.5_64MongoDB版本：mongodb-linux-x86_64-rhel62-v3.2-latest.tgzMemory:2G
2.配置环境变量,修改与之相关的系统参数在该文件中末尾添加这些参数,否则后面会有相应地告警信息# vim /etc/security/limits.conf*-fsize unlimited # (file size)*-cpu unlimited # (cpu time)*-as unlimited # (virtual memory size)*-nofile 64000 # (open files)*-nproc 64000 # (processes/threads)
mongodb soft nofile 64000mongodb hard nofile 64000mongodb soft nproc 32000mongodb hard nproc 32000
在proc中关闭NUMA# echo 0 > /proc/sys/vm/zone_reclaim_mode # sysctl -w vm.zone_reclaim_mode=0vm.zone_reclaim_mode = 0# echo never > /sys/kernel/mm/transparent_hugepage/enabled# echo never > /sys/kernel/mm/transparent_hugepage/defrag
# vim /etc/rc.local if test -f /sys/kernel/mm/transparent_hugepage/enabled; then echo never > /sys/kernel/mm/transparent_hugepage/enabledfiif test -f /sys/kernel/mm/transparent_hugepage/defrag; then echo never > /sys/kernel/mm/transparent_hugepage/defragfi
上述操作的目的是解决类似如下的告警信息：2015-03-19T00:43:27.760+0800 I CONTROL ** WARNING: /sys/kernel/mm/transparent_hugepage/enabled is 'always'.2015-03-19T00:43:27.760+0800 I CONTROL ** We suggest setting it to 'never'
3.创建mongodb运行用户和目录等因为高版本的mongodb需要独立的用户来运行mongod进程，像mysqld需要mysql用户一样,所以这里我推荐创建一个用户。如果不创建的话，也能运行，不过日志中会有相应的告警提示信息。# useradd mongodb# 注意:mongodb这个用户名可以取别的# passwd mongodbChanging password for user mongodb.New password: BAD PASSWORD: it is based on a dictionary wordBAD PASSWORD: is too simpleRetype new password: passwd: all authentication tokens updated successfully.#
创建需要的目录，并修改权限,切换到mongodb用户模式# su - mongodb$ mkdir -p {data,log,conf}$ lltotal 12drwxrwxr-x 2 mongodb mongodb 4096 Jan 25 14:03 confdrwxrwxr-x 2 mongodb mongodb 4096 Jan 25 14:03 datadrwxrwxr-x 2 mongodb mongodb 4096 Jan 25 14:03 log$
4.上传安装包，解压安装$ wget http://downloads.mongodb.org/linux/mongodb-linux-x86_64-rhel62-v3.2-latest.tgz$ lltotal 64900drwxrwxr-x 2 mongodb mongodb 4096 Jan 25 14:03 confdrwxrwxr-x 2 mongodb mongodb 4096 Jan 25 14:03 datadrwxrwxr-x 2 mongodb mongodb 4096 Jan 25 14:03 log-rw-rw-r-- 1 mongodb mongodb 66443467 Jan 23 02:47 mongodb-linux-x86_64-rhel62-v3.2-latest.tgz$ tar -zxf mongodb-linux-x86_64-rhel62-v3.2-latest.tgz $ mv mongodb-linux-x86_64-rhel62-3.2.1-83-g187028f/ mongodb3.2.1$ rm -f mongodb-linux-x86_64-rhel62-v3.2-latest.tgz# 可以不用删除
5.创建配置文件$ vim /home/mongodb/.bash_profile export PATH=/home/mongodb/mongodb3.2.1/bin:$PATH$ source /home/mongodb/.bash_profile $ vim conf/mongodb.conf# bind_ip=192.168.0.100 # ip绑定port=37000# 端口号dbpath=/home/mongodb/data/logpath=/home/mongodb/log/mongodb.log # 输出日志文件名称pidfilepath=/home/mongodb/mongobd.pid # pid文件名称journal=truemaxConns=50000 # 最大连接数logappend=true# 日志输出方式fork=true # 以守护进程的方式运行，创建服务器进程# httpinterface=false # web界面noauth=true cpu=true$
6.启动并进行简单测试启动有两种方式启动，直接命令行启动，还有一种就是使用配置文件启动,强烈建议使用配置文件启动。

可见,使用db.shutdownServer()和使用kill -2 比较放心些。所以我们最好能采用这两种的其中一个即可。
7.总结 本文档是基于目前相对较新的版本在测试过境中搭建的过程,而且是单机环境。目的是从头开始尝试mongodb这种NoSQL数据库的使用。个人看重的除了mongodb自身的优势外,最喜欢它的复制集和分片功能。在这两点上,目前关系型数据库实现起来相对较复杂，不易维护管理。
