首先从官网下载mongodb的安装包http://www.mongodb.org/downloads我的系统是redhat5.8所有选择相应的版本包就ok现在最新版是3.0.3
解压mongodb-linux-x86_64-rhel55-3.0.3.tgz
[[email protected] ~]# tar zxvf mongodb-linux-x86_64-rhel55-3.0.3.tgz -C /opt/ mongodb-linux-x86_64-rhel55-3.0.3/README mongodb-linux-x86_64-rhel55-3.0.3/THIRD-PARTY-NOTICES mongodb-linux-x86_64-rhel55-3.0.3/GNU-AGPL-3.0 mongodb-linux-x86_64-rhel55-3.0.3/bin/mongodump mongodb-linux-x86_64-rhel55-3.0.3/bin/mongorestore mongodb-linux-x86_64-rhel55-3.0.3/bin/mongoexport mongodb-linux-x86_64-rhel55-3.0.3/bin/mongoimport mongodb-linux-x86_64-rhel55-3.0.3/bin/mongostat mongodb-linux-x86_64-rhel55-3.0.3/bin/mongotop mongodb-linux-x86_64-rhel55-3.0.3/bin/bsondump mongodb-linux-x86_64-rhel55-3.0.3/bin/mongofiles mongodb-linux-x86_64-rhel55-3.0.3/bin/mongooplog mongodb-linux-x86_64-rhel55-3.0.3/bin/mongoperf mongodb-linux-x86_64-rhel55-3.0.3/bin/mongod mongodb-linux-x86_64-rhel55-3.0.3/bin/mongos mongodb-linux-x86_64-rhel55-3.0.3/bin/mongo [[email protected] opt]# ln -sv mongodb-linux-x86_64-rhel55-3.0.3/ mongodb create symbolic link `mongodb' to `mongodb-linux-x86_64-rhel55-3.0.3/'
3.创建mongodb用户
[[email protected] /]# useradd mongodb
4.创建相应文件目录并修改权限
[[email protected] /]# mkdir /data/db -p [[email protected] /]# chown mongodb:mongodb /data/ -R [[email protected] opt]# chown -R mongodb:mongodb /opt/*
5.添加PATH环境变量在shell下正常访问mongodb的应用工具
[[email protected] bin]# vim /etc/profile.d/mongodb.sh export PATH=$PATH:/opt/mongodb/bin [[email protected] bin]# source /etc/profile.d/mongodb.sh [[email protected] bin]# echo $PATH /usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/opt/mongodb/bin
6.创建mongodb的PID存放目录
[[email protected] run]# mkdir /var/run/mongodb [[email protected] run]# chown mongodb:mongodb /var/run/mongodb/ -R [root[email protected] opt]# mongod --dbpath /data/db/ --logpath /var/log/mongodb.log --logappend --port 27017 --pidfilepath /var/run/mongodb/mongodb.pid --maxConns 250 --rest --httpinterface --fork about to fork child process, waiting until server is ready for connections. forked process: 4060 child process started successfully, parent exiting --maxConns 250 ：表示最大连接数是250个 --rest --httpinterface : web接口，指定这项28017端口才能启用 --fork ：后台运行
7.安装过程中遇见的问题
装好之后连接出现以下警告
(1).[[email protected] ~]# mongo MongoDB shell version: 3.0.3 connecting to: test Server has startup warnings: 2015-06-15T20:27:49.892+0800 I CONTROL [initandlisten] ** WARNING: You are running this process as the root user, which is not recommended. 2015-06-15T20:27:49.892+0800 I CONTROL [initandlisten]
出现这个问题就查看关于mongodb的文件权限，主要是/opt /data/db/ /var/run/mongodb/ /var/log/mongodb.log的权限因为启动初始化时以root用户的权限在运行，所以这些目录下的权限可能会变成root root
(2).[[email protected] db]$ mongod --dbpath /data/db/ --logpath /var/log/mongodb.log --logappend --port 27017 --pidfilepath /var/run/mongodb/mongodb.pid --maxConns 250 --rest --httpinterface --fork 2015-06-15T17:41:25.721+0800 I CONTROL [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/enabled is 'always'. 2015-06-15T17:41:25.721+0800 I CONTROL [initandlisten] ** We suggest setting it to 'never' 2015-06-15T17:41:25.721+0800 I CONTROL [initandlisten] 2015-06-15T17:41:25.721+0800 I CONTROL [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/defrag is 'always'. 2015-06-15T17:41:25.721+0800 I CONTROL [initandlisten] ** We suggest setting it to 'never'
修改两个参数即可
echo "never" > /sys/kernel/mm/transparent_hugepage/enabled echo "never" > /sys/kernel/mm/transparent_hugepage/defrag
8.安装成功并登录
[[email protected] ~]# ss -tanlp | grep mongod 0 0 *:27017 *:* users:(("mongod",4095,6)) 0 0 *:28017 *:* users:(("mongod",4095,8)) [[email protected] ~]# mongo MongoDB shell version: 3.0.3 connecting to: test > help db.help() help on db methods db.mycoll.help() help on collection methods sh.help() sharding helpers rs.help() replica set helpers help admin administrative help help connect connecting to a db help help keys key shortcuts help misc misc things to know help mr mapreduce show dbs show database names show collections show collections in current database show users show users in current database show profile show most recent system.profile entries with time >= 1ms show logs show the accessible logger names show log [name] prints out the last segment of log in memory, 'global' is default use <db_name> set current database db.foo.find() list objects in collection foo db.foo.find( { a : 1 } ) list objects in foo where a == 1 it result of the last line evaluated; use to further iterate DBQuery.shellBatchSize = x set default number of items to display on shell exit quit the mongo shell
登录web接口 28017端口
9.关闭服务器
(1).[[email protected] ~]# mongod --shutdown killing process with pid: 3936 (2).[[email protected] ~]# killall mongod
10.给mongodb编写配置文件/etc/mongodb.conf
[[email protected] ~]# grep -v ^# /etc/mongodb.conf logpath=/var/log/mongodb.log logappend=true fork = true dbpath=/data/db pidfilepath = /var/run/mongodb/mongodb.pid rest = true httpinterface = true
启动
[[email protected] ~]# mongod -f /etc/mongodb.conf about to fork child process, waiting until server is ready for connections. forked process: 4169 child process started successfully, parent exiting [[email protected] ~]# ss -tanlp | grep mongod 0 0 *:27017 *:* users:(("mongod",4169,6)) 0 0 *:28017 *:* users:(("mongod",4169,8))
11.用service mongodb * 来启动mongodb
启动脚本：/etc/rc.d/init.d/mongod
#!/bin/bash
# mongod - Startup script for mongod
# chkconfig: 35 85 15

NUMACTL_ARGS="--interleave=all"
if which numactl >/dev/null 2>/dev/null && numactl $NUMACTL_ARGS ls / >/dev/null 2>/dev/null
then
NUMACTL="numactl $NUMACTL_ARGS"
else
NUMACTL=""
fi
start()
{
echo -n $"Starting mongod: "
daemon --user "$MONGO_USER" $NUMACTL $mongod $OPTIONS
RETVAL=$?
echo
[ $RETVAL -eq 0 ] && touch /var/lock/subsys/mongod
}
stop()
{
echo -n $"Stopping mongod: "
killproc -p "$PIDFILE" -d 300 /opt/mongodb/bin/mongod
RETVAL=$?
echo
[ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/mongod
}
restart () {
stop
start
}
ulimit -n 12000
RETVAL=0
case "$1" in
start)
start

stop

restart|reload|force-reload)
restart

condrestart)
[ -f /var/lock/subsys/mongod ] && restart || :

status)
status $mongod
RETVAL=$?
;;

echo "Usage: $0 {start|stop|status|restart|reload|force-reload|condrestart}"
RETVAL=1
esac
exit $RETVAL
测试启动
