[Linux] CentOS + Dropbox + git

1. CentOS上用command line安裝Dropbox
> wget --no-check-certificate -O dropbox.tar.gz "https://www.dropbox.com/download?plat=lnx.x86_64"

> tar xvfz dropbox.tar.gz

> cd .dropbox-dist ; ./dropboxd

這時候會出現一串URL，用browser去連那個URL，然後輸入dropbox的帳號密碼。

> ./dropboxd &

2. 安裝git

> sudo yum install git

3. 設定git

> git config --global user.name "yourname"

> git config --global user.email "username@e-mail"

> git config --global alias.st status

> git config --global alias.co checkout

> git config --global color.ui true

> git config --global credential.helper cache

> git config --global credential.helper 'cache --timeout=3600'

> git config --global http.sslVerify false

4. dropbox上repository設定

> mkdir -p ~/Dropbox/Project/newproject

> cd ~/Dropbox/Project/newproject

> git init --bare

5. 開發目錄repository設定

> mkdir -p ~/Project/newproject

> cd ~/Project/newproject

> git init

把code copy進~/Project/newproject目錄下

6. commit code到dropbox

> git add .

> git commit -m "initial version"

> git remote add dropbox ~/Dropbox/Project/newproject
> git push dropbox master

7. 測試pull

刪除project目錄

> rm -rf ~/Project/newproject

重建project目錄

> mkdir ~/Project/newproject

> git init
> git remote add dropbox ~/Dropbox/Project/newproject

> git pull dropbox master

SSH 免密碼登錄備忘

$ ssh-keygen -t rsa
$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
$ chmod 600 ~/.ssh/authorized_keys
這個步驟經常忘記
$ ssh localhost

[Linux] CentOS的apache設定with selinux

安裝好CentOS，啟動httpd後，在/var/www/html下建了新目錄後，browse時會發現：
403 Forbidden
到error_log去看，會發現：
(13)Permission denied: access to /search/ denied

解法方法：

方法1
# vi /etc/sysconfig/selinux
SELINUX=enforcing --> SELINUX=disabled

# reboot

方法2
# ls -Z
drwxr-xr-x apache apache user_u:object_r:user_home_t search

＃ sudo chcon -R -h -t httpd_sys_content_t search

要連線遠端的mysql時，error_log會出現：（遠端的mysql帳號，密碼，權限設定都沒問題）
Can't connect to MySQL server on '192.168.0.9'

解法方法：

＃ sudo setsebool -P httpd_can_network_connect_db 1
# sudo service httpd restart

用curl時，command line正常，但在httpd下，卻出現：
curl error no 7
Permission denied

解決方法：

＃ sudo setsebool -P httpd_can_network_connect 1
# sudo service httpd restart

[Ubuntu] stardict擴充字典檔

1. 下載字典檔

http://stardict.sourceforge.net/Dictionaries.php

2. 安裝字典檔

[Ubuntu] 升級9.10後,vmware滑鼠失靈了

Ubuntu升級9.10後,vmware滑鼠失靈了
一整個很怪,無法點任何東西,然後鼠標會亂飄

解決方法如下:

修改 /etc/vmware/bootstrap 這個檔案
加入一行
VMWARE_USE_SHIPPED_GTK=force

重新執行vmware

[Linux] kubuntu的software update一直有4個blocked updates

kubuntu的software update一直有4個blocked updates
要如何消除呢?

sudo apt-get update
sudo apt-get dist-upgrade

[Linux] CentOS無法升級時

CentOS在yum update時，有時候會有Dependency的Error。
此時，執行

yum clean metadata

有時候，可以解決問題。

[Kubuntu] apt-get update時，GPG error

修改完/etc/apt/sources.list後，
在做apt-get update時，出現

W: GPG error: http://ppa.launchpad.net jaunty Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 632D16BB0C713DA6
W: You may want to run apt-get update to correct these problems

此時，執行

gpg --keyserver subkeys.pgp.net --recv 632D16BB0C713DA6
gpg --export --armor 632D16BB0C713DA6 | sudo apt-key add -

即可解決。

[Linux] 在現有的Hadoop Cluster上安裝與運行NUTCH

This tutorial uses 5 CentOS Linux Servers to build Hadoop cluster.
machine1(192.168.0.1) : namenode, jobtracker
machine2-5(192.168.0.2-5) : datanode

1. Add a user and create working directories for Nutch and Hadoop.

sudo useradd -d /home/nutch nutch
sudo mkdir /home/search
sudo chown -R hadoop:hadoop /home/search
sudo as hadoop and change to the home directory.

Apply this step to machine1-5.

2. Download and upgrade JAVA

download the latest java package from the link blow:
http://www.java.com/en/download/manual.jsp#lin
chmod a+x jdk-6u14-linux-i586-rpm.bin
./jdk-6u14-linux-i586-rpm.bin

Apply this step to machine1-5.

3. Modify /etc/hosts
Add these hosts to /etc/hosts

machine1 192.168.0.1
machine2 192.168.0.2
machine3 192.168.0.3
machine4 192.168.0.4
machine5 192.168.0.5

Apply this step to machine1-5.

[Linux] 無法compile pftp shit edition的問題

在Linux下，compile pftp shit edition時，會出現

In function ‘int open(const char*, int, ...)’, inlined from ‘bool CTCP::ReadFile(char*, long int)’ at tcp.cc:1180:
/usr/include/bits/fcntl2.h:51: error: call to ‘__open_missing_mode’ declared with attribute error: open with O_CREAT in second argument needs 3 arguments make[1]: *** [tcp.o] Error 1

解決方法：

編輯src/tcp.cc
跳到1180行
找到
open(name, O_CREAT | O_TRUNC | O_RDWR | O_BINARY)) == -1) {
改成
open(name, O_CREAT | O_TRUNC,0664 | O_RDWR | O_BINARY)) == -1) {
然後make dynamic

[Linux] SSH的Remote Forwarding

早大的網路，管的真的很嚴。
但還是有辦法突破^_^

A : 學校的個人電腦 (Linux, Private IP)
B : SSH Server (Linux, Public IP, 有Firewall,對外只能用port 22)
C : 家裏的電腦 (皆可)

A可以連到B,C
B可以連到C，但不能連到A
C可以連到B，但不能連到A

要如何從C連到A呢？
可以用SSH Remote Forwarding

在A上執行

ssh -N -R 55588:localhost:22 user_of_B@ip.of.B

此時就可以從C用SSH到B之後，再從B SSH到A了

C_SHELL> ssh user_of_B@ip.of.B
B_SHELL> ssh -p 55588 user_of_A@localhost
