遇到的问题

启动时的警告信息

2015-03-06T21:01:15.526-0800 I CONTROL  [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/defrag is 'always'.

stackoverflow上的回答

Official MongoDB documentation gives several solutions for this issue. You can also try this solution, which worked for me:
Open /etc/init/mongod.conf file.
Add the lines below immediately after chown $DEAMONUSER /var/run/mongodb.pid and before end script.
Restart mongod (service mongod restart).
Here are the lines to add to /etc/init/mongod.conf:
if test -f /sys/kernel/mm/transparent_hugepage/enabled; then
echo never > /sys/kernel/mm/transparent_hugepage/enabled
fi
if test -f /sys/kernel/mm/transparent_hugepage/defrag; then
echo never > /sys/kernel/mm/transparent_hugepage/defrag
fi
That's it!

可惜我英语太渣，居然没有理解这句话（看漏了个单词before，然后就加在end script后面了）：Add the lines below immediately after chown $DEAMONUSER /var/run/mongodb.pid and before end script.

service mongod stop 不起作用

返回信息：

stop: Unknown instance

解决方法：
删除/var/lib/mongodb/mongod.lock，然后重启。

Atom

不能显示中文？

步骤

打开 style.less 文件 ( 唤出 Command Palette 找到 Open Your Stylesheet )。
粘贴下面代码并保存。(其中 "ubuntu mono" 、"ubuntu" 替换为你希望的西文字体名)。

/* 等宽字体 */
@mono-font-family: "ubuntu mono", "Hiragino Sans GB", "Microsoft YaHei","WenQuanYi Micro Hei", sans-serif;
/* 非等宽字体 */
@font-family: "ubuntu", "Hiragino Sans GB", "Microsoft YaHei","WenQuanYi Micro Hei", sans-serif;
