mongodb学习之:mongo安装以及远程访问
在linux下通过apt-get install mongo的方式一键式安装mongo
安装后mongo的配置文件位于/etc/mongodb.conf. 里面有mongo的各项配置,文件内容如下:重要的主要有下面几项:
1 dbpath:存放数据库文件的地方
2 logpath: 存放log的地方
3 bind_ip = 127.0.0.1。安装好之后默认只允许本地访问。限制访问的IP为127.0.0.1。如果要允许所有的地址访问。需要将此行注释掉
4 port:访问的端口号
5 auth=true (添加帐号,密码认证)
root@zhf-maple:/home/zhf# cat /etc/mongodb.conf
# mongodb.conf
# Where to store the data.
dbpath=/var/lib/mongodb
#where to log
logpath=/var/log/mongodb/mongodb.log
logappend=true
bind_ip = 127.0.0.1
#port = 27017
# Enable journaling, http://www.mongodb.org/display/DOCS/Journaling
journal=true
# Enables periodic logging of CPU utilization and I/O wait
#cpu = true
# Turn on/off security. Off is currently the default
#noauth = true
#auth = true
# Verbose logging output.
#verbose = true
# Inspect all client data for validity on receipt (useful for
# developing drivers)
#objcheck = true
# Enable db quota management
#quota = true
# Set oplogging level where n is
# 0=off (default)
# 1=W
# 2=R
# 3=both
# 7=W+some reads
#oplog = 0
# Diagnostic/debugging option
#nocursors = true
# Ignore query hints
#nohints = true
# Disable the HTTP interface (Defaults to localhost:27018).
#nohttpinterface = true
# Turns off server-side scripting. This will result in greatly limited
# functionality
#noscripting = true
# Turns off table scans. Any query that would do a table scan fails.
#notablescan = true
# Disable data file preallocation.
#noprealloc = true
# Specify .ns file size for new databases.
# nssize = <size>
# Accout token for Mongo monitoring server.
#mms-token = <token>
# Server name for Mongo monitoring server.
#mms-name = <server-name>
# Ping interval for Mongo monitoring server.
#mms-interval = <seconds>
# Replication Options
# in replicated mongo databases, specify here whether this is a slave or master
#slave = true
#source = master.example.com
# Slave only: specify a single database to replicate
#only = master.example.com
# or
#master = true
#source = slave.example.com
# Address of a server to pair with.
#pairwith = <server:port>
# Address of arbiter server.
#arbiter = <server:port>
# Automatically resync if slave data is stale
#autoresync
# Custom size for replication operation log.
#oplogSize = <MB>
# Size limit for in-memory storage of op ids.
#opIdMem = <bytes>
# SSL options
# Enable SSL on normal ports
#sslOnNormalPorts = true
# SSL Key file and password
#sslPEMKeyFile = /etc/ssl/mongodb.pem
#sslPEMKeyPassword = pass
安装后之后输入mongo命令进入shell界面
root@zhf-maple:/home/zhf# mongo

设置远程连接:
配置文件修改如下:注释掉bind_ip,
#bind_ip = 127.0.0.1
