MongoDB:

https://docs.mongodb.com/manual/tutorial/install-mongodb-on-linux/#install-mongodb-community-edition

一、下载安装
# curl -O https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel62-3.2.9.tgz 或
# wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel62-3.2.9.tgz # tar -xf mongodb-linux-x86_64-rhel62-3.2.9.tgz -C /opt/
# ln -s /opt/mongodb-linux-x86_64-rhel62-3.2.9/ /opt/mongodb
# cat >>/etc/profile <<HERE
PATH=$PATH:/opt/mongodb/bin
HERE
# source /etc/profile
# mkdir -p /opt/mongodb/{log,db,conf}

二；启动
# mongod --fork --httpinterface --rest --jsonp --setParameter enableLocalhostAuthBypass=0 --pidfilepath /opt/mongodb/mongod.pid --dbpath /opt/mongodb/db --logpath /opt/mongodb/log/mongod.log --logappend --logRotate rename --timeStampFormat ctime
/** 可以加入/etc/rc.d/rc.local，以随操作系统重启时自启动 **/

/** 部分参数解释 **/
--fork #后台daemon运行
--bind_ip #监听IP地址列表,以逗号分隔
--port #监听端口,默认27017
--setParameter enableLocalhostAuthBypass=0 #所有接口都需要认证
--pidfilepath #pid文件
--dbpath #db存放路径
--logpath #日志文件
--config #配置文件
--auth #启用认证
--httpinterface #启用web接口
--rest #rest api
--jsonp #json api
/** 如果闲命令参数太多，可以指定配置文件 **/
WARNING
Ensure that the HTTP status interface, the REST API, and the JSON API are all disabled in production environments to prevent potential data exposure and vulnerability to attackers
root@master:~#netstat -tunlp|grep mongod
tcp 0 0 0.0.0.0:28017 0.0.0.0:* LISTEN 11896/mongod
tcp 0 0 0.0.0.0:27017 0.0.0.0:* LISTEN 11896/mongod
默认监听端口，db端口为27017, web端口为28017
# vi /etc/sysconfig/iptables
-A INPUT -p tcp -m state --state NEW -m tcp --dport 27017 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 28017 -j ACCEPT

三、关闭
# mongod --shutdown --dbpath /opt/mongod/db
还可以
命令行模式执行shutdown
# use admin
db.shutdownServer()
或
mongo admin --port 27017 --eval "db.shutdownServer()"

四、配置文件
默认的二进制包没有配置文件模板，可以从源码包内提取
# cp -rp /usr/local/src/mongodb-src-r3.2.9/rpm/mongod.conf /opt/mongodb/conf/

/** 以下是一个简单的对应以上命令行参数的配置文件 **/

# mongod.conf
# for documentation of all options, see:
# http://docs.mongodb.org/manual/reference/configuration-options/ # where to write logging data.
systemLog:
destination: file
logAppend: true
logRotate: rename
timeStampFormat: ctime
path: /opt/mongodb/log/mongod.log

# Where and how to store data.
storage:
dbPath: /opt/mongodb/db
journal:
enabled: true
# engine:
# mmapv1:
# wiredTiger:
# how the process runs
processManagement:
fork: true # fork and run in background
pidFilePath: /opt/mongodb/mongod.pid # location of pidfile

# network interfaces
net:
port: 27017
#bindIp: 127.0.0.1 # Listen to local interface only, comment to listen on all interfaces.
http:
enabled: true
JSONPEnabled: true
RESTInterfaceEnabled: true
setParameter:
enableLocalhostAuthBypass: false

#security:
#operationProfiling:
#replication:

## Enterprise-Only Options
#auditLog:
#snmp:
更多参数和解释请参看官方文档

五、 init管控启动脚本
# useradd -s /sbin/nologin -r mongod
# chown -R mongod: /opt/mongodb-linux-x86_64-rhel62-3.2.9
# cp -rp/usr/local/src/mongodb-src-r3.2.9/rpm/init.d-mongod /etc/init.d/mongod
　/**　模板仍可以从 源码包里面取 **/
# chmod +x /etc/init.d/mongod
# sed -i '/CONFIGFILE=/i MONGOD="/opt/mongodb/bin/mongod"' /etc/init.d/mongod
# sed -i '/CONFIGFILE=/s:/etc/mongod.conf:/opt/mongodb/conf/mongod.conf:g' /etc/init.d/mongod

六、修改内核参数
# cat >>/etc/rc.d/rc.local <<HERE
# echo never > /sys/kernel/mm/transparent_hugepage/enabled
# echo never > /sys/kernel/mm/transparent_hugepage/defrag
# HERE

七，重启服务访问；
# service mongod restart http://IP:28017/
