这是单机版本的MongoDB自动部署，手动部署可以参考我的另一篇文章：
首先下载mongodb-linux-x86_64-2.2.0.tgz, 解压后放到工程目录mongodb下。
然后准备启动脚本mongodb:
#!/bin/sh ### BEGIN INIT INFO # Provides: mongodb # Required-Start: # Required-Stop: # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: mongodb # Description: mongo db server ### END INIT INFO . /lib/lsb/init-functions PROGRAM=/usr/mongodb/bin/mongod MONGOPID=`ps -ef | grep 'mongod' | grep -v grep | awk '{print $2}'` test -x $PROGRAM || exit 0 case "$1" in start) ulimit -n 3000 log_begin_msg "Starting MongoDB server" $PROGRAM --fork --quiet -journal -maxConns=100 -rest --logpath /data/db/journal/mongdb.log log_end_msg 0 ;; stop) log_begin_msg "Stopping MongoDB server" if [ ! -z "$MONGOPID" ]; then kill -15 $MONGOPID fi log_end_msg 0 ;; status) ;; *) log_success_msg "Usage: /etc/init.d/mongodb {start|stop|status}" exit 1 esac exit 0最后看一下install.sh
#!/bin/bash source ../common/tool.sh copyFolder ./mongodb-linux-x86_64-2.2.0 /usr/mongodb-linux-x86_64-2.2.0 createLink "./mongodb-linux-x86_64-2.2.0" "/usr/mongodb" createFolder "/data/db/journal" chmod -R 777 /data/db/ copyFile mongodb $PWD /etc/init.d chmod +x /etc/init.d/mongodb update-rc.d mongodb defaults service mongodb start看一下目前经常用到的common/tool.sh脚本的全貌：
