先找 osx 這個軟體 ssh secret socks , download : http://nihilex.com/secret-socks
如這頁說明裝好 ssh secret socks
http://www.pairsdoll.com/secret-socks.html/
在 OSX 的 網路 setting 那邊應該 這軟體會幫忙設好, 若沒有就照下面畫面設定
那頁假設是用 local 的 SOCKS PORT 是 9999 那麼 Firefox 的 設定就這樣設定

進 vmware management console 加一個 Harddisk 後, 這樣讓 linux 重新 scan 一次 device:
# echo "- - -" > /sys/class/scsi_host/host#/scan fdisk -l tail -f /var/log/message #
那個 host# 這樣找:
# ls /sys/class/scsi_host
再下 dmesg 看看有沒有出現
首先 ubuntu server 上 /etc/ssh/sshd_config , 加這一行:
putty 的設定要設兩種: for big5 的 跟 for utf8 的 兩種 config , 在連接 server 時選擇要要那種字元集
Continue reading ‘big5 utf8 很難搞系列 , 現在比較順利可以切換 兩種不同字元集環境了… ubuntu / LANG’ »

Getting a new virtual machine up and running from the default AMI is easy. Here’s my cookbook:
Install basic services
yum install mysql mysql-server mysql-devel
yum install httpd httpd-devel
yum install php php-devel php-mysql php-gd php-dom php-pear php-json
yum install svn
Configure those services to start at boot
chkconfig –level 345 httpd on
chkconfig –level 345 mysqld on
chkconfig –list
Install APC
I couldn’t find a package, and this bug report explains why we have to use the beta.
yum install gcc pcre-devel
pecl install apc-beta
echo extension=apc.so > /etc/php.d/apc.ini
Install memcached
yum install libevent libevent-devel
curl -O http://memcached.googlecode.com/files/memcached-1.4.5.tar.gz
cd memcached-1.4.5
./configure
make ; make install

以前 打 www.apache.org 可能就是看到 apache web server 的 download , document ….等等, 但隨著越來越多開發者把他們的 project 標記成 apache license , apache 於是變成一個巨大的 project 集中地 – The Apache Software Foundation ….
apache web server 是排名第一的 web server 這不用說, 今天認識了 Lucene , Solr 這個應該算是 apache 第二大
Apache Lucene Java 分類是 database
http://projects.apache.org/projects/lucene_java.html
Apache Solr 是被分類在 web-framework, network-server
http://projects.apache.org/projects/solr.html
Supports a variety of Cross Language Clients and Protocols from Java, C, C++, C#, Ruby, Perl, Python, PHP
Features : http://activemq.apache.org/features-overview.html
有時需要用 vm 模擬一堆 server 的環境 , 開了 guest vm (linux) , 但是就是要進 console 後才能知道 IP address , 有些麻煩
這個 script 可以幫助一下, 把 該 server 取得的 IP address 顯示在 console 上, 把它寫成一個 bash 或加到 /etc/rc.local 去
IPADD=`/sbin/ifconfig | sed '/Bcast/!d' | awk '{print $2}'| awk '{print $2}' FS=":"`
echo " $IPADD" >> /etc/issue
VBoxManage clonehd <uuid>|<filename> <outputfile>
