CentOS编译安装MongoDB

一、环境

系统 CentOS6.4x64最小化安装

IP 192.168.3.33

二、安装

[root@mongodb-2 ~]# curl -O https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.0.5.tgz[root@mongodb-2 ~]# tar xf mongodb-linux-x86_64-3.0.5.tgz [root@mongodb-2 ~]# ln -s /usr/local/mongodb-linux-x86_64-3.0.5/ /usr/local/mongodb

设置环境变量

[root@mongodb-2 ~]# tail -3 /etc/profile#set for mongodbexport MONGODB_HOME=/usr/local/mongodbexport PATH=$MONGODB_HOME/bin:$PATH#重新加载环境变量[root@mongodb-2 ~]# source /etc/profile[root@mongodb-2 ~]# echo $PATH/usr/local/mongodb/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin#验证结果[root@mongodb-2 ~]# mongod --versiondb version v3.0.5git version: 8bc4ae20708dbb493cb09338d9e7be6698e4a3a3

建立目录

[root@mongodb-2 ~]# mkdir -p /usr/local/mongodb/data[root@mongodb-2 ~]# mkdir -p /usr/local/mongodb/log[root@mongodb-2 ~]# mkdir -p /usr/local/mongodb/conf

建立配置文件

[root@mongodb-2 ~]# cat /usr/local/mongodb/conf/mongodb.conf#bind_ip=0.0.0.0port=27017dbpath=/usr/local/mongodb/datalogpath=/usr/local/mongodb/log/mongodb.logpidfilepath=/usr/local/mongodb/log/mongodb.piddirectoryperdb=truelogappend=trueoplogSize=1000fork=true#noprealloc=truemaster=true

增加mongodb用户及设置权限

[root@mongodb-2 ~]# useradd mongodb -M -s /sbin/nologin [root@mongodb-2 ~]# chown -R mongodb.mongodb /usr/local/mongodb-linux-x86_64-3.0.5

启动服务

[root@mongodb-2 ~]# mongod -f /usr/local/mongodb/conf/mongodb.conf about to fork child process, waiting until server is ready for connections.forked process: 1545child process started successfully, parent exiting#测试[root@mongodb-2 ~]# mongo admin

编写服务器启动脚本

[root@mongodb-2 ~]# cat /etc/init.d/mongod #!/bin/sh## mongodb      init file for starting up the MongoDB server## chkconfig:   - 20 80# description: Starts and stops the MongDB daemon that handles all \#              database requests.# Source function library.. /etc/rc.d/init.d/functionsexec="/usr/local/mongodb/bin/mongod"prog="mongod"logfile="/usr/local/mongodb/log/mongodb.log"options=" -f /usr/local/mongodb/conf/mongodb.conf "[ -e /etc/sysconfig/$prog ] && . /etc/sysconfig/$proglockfile="/var/lock/subsys/mongod"start() {    [ -x $exec ] || exit 5    echo -n $"Starting $prog: "    daemon --user mongodb "$exec --quiet $options run >> $logfile 2>&1 &"    retval=$?    echo    [ $retval -eq 0 ] && touch $lockfile    return $retval}stop() {    echo -n $"Stopping $prog: "    killproc $prog    retval=$?    echo    [ $retval -eq 0 ] && rm -f $lockfile    return $retval}restart() {    stop    start}reload() {    restart}force_reload() {    restart}rh_status() {    # run checks to determine if the service is running or use generic status    status $prog}rh_status_q() {    rh_status >/dev/null 2>&1}case "$1" in    start)        if test -f /sys/kernel/mm/transparent_hugepage/defrag; then          echo never > /sys/kernel/mm/transparent_hugepage/defrag        fi        if test -f /sys/kernel/mm/transparent_hugepage/enabled; then          echo never > /sys/kernel/mm/transparent_hugepage/enabled        fi        rh_status_q && exit 0        $1        ;;    stop)        rh_status_q || exit 0        $1        ;;    restart)        $1        ;;    reload)        rh_status_q || exit 7        $1        ;;    force-reload)        force_reload        ;;    status)        rh_status        ;;    condrestart|try-restart)        rh_status_q || exit 0        restart        ;;    *)        echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload}"        exit 2esacexit $?#赋予脚本执行权限[root@mongodb-2 ~]# chmod +x /etc/init.d/mongod#重启服务[root@mongodb-2 ~]# /etc/init.d/mongod restartStopping mongod:                                           [  OK  ]Starting mongod:                                           [  OK  ][root@mongodb-2 ~]# netstat -tunlp |grep mongtcp        0      0 0.0.0.0:27017               0.0.0.0:*                   LISTEN      1759/mongod  #添加到开机自启动[root@mongodb-2 ~]# chkconfig --add mongod[root@mongodb-2 ~]# chkconfig mongod on

mongodb配置文件的参数说明

mongodb的参数说明：--dbpath        数据库路径(数据文件)--logpath       日志文件路径--master        指定为主机器--slave         指定为从机器--source        指定主机器的IP地址--pologSize     指定日志文件大小不超过64M.因为resync是非常操作量大且耗时，最好通过设置一个足够大的oplogSize来避免resync(默认的 oplog大小是空闲磁盘大小的5%)。--logappend     日志文件末尾添加--port          启用端口号--fork          在后台运行--only          指定只复制哪一个数据库--slavedelay    指从复制检测的时间间隔--auth          是否需要验证权限登录(用户名和密码)
