时间过得真快呀
一眨眼
我到这个公司、这个部门已经快5年了
想想5年前
正是互联网行业的第一个春天
年少轻狂的我
那是一年换一个公司呀
没想到
经历过短暂失业的我
对于这份工作是如此的在意
我都有点佩服我自己了
呵呵
居然在一个公司的一个部门呆了5年时间之久
我想如果不是公司搬家
我可能会在长安街上的那幢写字楼里的某一个固定位置呆上5年也不一定哟
（公司搬家前，3年多的时间我一直就坐在那个位置没动过，这在公司我想应该是少有的）
在这5年间
我娶妻生子
我置业安家
这5年，可能是我人生中最重要的5年
5年来
我一直就呆在NO部门
领导换了一茬又一茬
不变的唯有像我一样的普通员工
连老板都说我们部门是忠诚度很高的部门：）
忠诚度高也没见加薪
呵呵
做一个优秀的系统管理员曾经是我的理想
（现在好像都没有“理想”了：）
从参加工作到现在
倒也是一直在为之而努力
但到现在
这个目标好像还没有完全达到：（
今天是我作为NO的员工最后一次值晚班
下周我就要搬到一个几乎全是年轻人的团队里去了
面临着新的工作、新的挑战
我不但有点好奇
还有点兴奋
嗯啦
看来我还没老
呵呵
http://httpd.apache.org/docs/2.2/new_features_2_2.html
相对于以前的版本
2.2的配置文件更结构清晰了
因为他把原来一个配置文件httpd.conf
变成了分功能的conf.d/*.conf
不过需要在httpd.conf中把相应的注释去掉才行
而且
从2.2的版本还是
缺省打开了大文件支持
这样再碰上大于2G的文件的时候
系统也不会有问题
原文是英文的，在这里
最简单的办法就是
rm ./-filename
(这里"-filename"在当前目录下)
很多命令，尤其是那些使用"getopt(3)"做常规参数解析的
会接受"–"作为参数，而且这意味着“这是最后一个选项”
所以，你的rm的版本也许能够操作"rm — -filename"这种方式
还有一些没有用getopt()的版本的rm认为单个"-"跟上面提到的"–"一样的作用
所以在这种版本的rm，可以用命令"rm - -filename"
以下的例子都使用了下面的这几个变量
TXTFILE=/tmp/textfile
ATTFILE=/tmp/binary_file
SUBJECT="Your attachment"
MAILTO=user@where.ever
一共可以有n种办法
下面列出几种
uuencode $ATTFILE $ATTFILE | \
mail -s "$SUBJECT" $MAILTO
(uuencode $FILE1 $FILE1; uuencode $FILE2\
$FILE2)| mail -s "$SUBJECT" $MAILTO
echo "From: $LOGNAME\n\
To: $MAILTO\nSubject: $SUBJECT\n\
Mime-Version: 1.0\n\
Content-Type: text/plain\n\
" > /tmp/file
cat $TXTFILE >> /tmp/file
/usr/lib/sendmail -t -oi < /tmp/file
metasend -b -s "$SUBJECT"\
-f $TXTFILE -m text/plain -e none -n \
-f $ATTFILE -m application/octet-stream \
-e base64 -t $MAILTO
mpack -s "$SUBJECT" -c \
application/octet-stream $ATTFILE $MAILTO
mutt -a $ATTFILE -s "$SUBJECT" $MAILTO <\
$TXTFILE
elm -s"$SUBJECT" -A $ATTFILE $MAILTO < $TXTFIL
uuenview -m $MAILTO -b -a $ATTFILE < $TXTFILE
nail -s "$SUBJECT" -a $ATTFILE $MAILTO < $TXTFILE
For a single file:
cat $TXTFILE | zmail.small -subject "$SUBJECT"\
-attach application/octet-stream:${ATTFILE}\
$MAILTO Bart Schaefer offers the following\
for multiple attachments.\
(untested by myself)
zmail.small -rf /dev/null -e \
'mail -z -s "$SUBJECT" $MAILTO' \
-e 'compcmd attach-file $ATTACHFILE \
application/msword base64 \
"$DESCRIPTION"' \
-e! 'compcmd send'
用techtips的两个T
配以本站缺省的theme的颜色–黄色
做了个简单的favicon
就是这样子
按照文档一步一步走
ssh登上这台sun fire v20z的sp
sp update flash all -i 192.168.111.111
此时在192.168.111.111这台update server上看到升级已经开始的log
但是到log显示传升级的image到正在升级的sp上了的时候
发现原来连到运行升级的程序的sp的session居然断了
按照以往的经验
感觉这次升级是失败了
于是停掉update server
又试了n回
都是这样
于是开始怀疑文档：）
终于有一次
当session断掉后
我没有停掉update server
突然某一刻我看update server上的log显示升级过程居然还在继续！！
于是我知道有戏了
果然
再过几分钟
升级完毕
再连上去
系统软件已经是新的版本了
公司机房有2台巨强的sun fire v20z的机器
这个机器也有远程管理口
一直以来也不知道怎么用的
直到今天出了点事情
如果有远程管理的话就可以不去机房
但是……
所以痛定思痛
我翻了下文档把远程管理配上了
这里是文档，文档来自http://www.sun.com/products-n-solutions/hardware/docs/html/817-5246-16/chap2.html#pgfId-999743
The Sun Fire V20z and Sun Fire V40z servers include a dedicated SP for complete server independence and maximum availability of server management. The SP is an embedded PowerPC that provides the following functions:
After supplying AC power to the server, you are ready to begin configuring the SP by setting an IP address and associated network settings for the SP. You can configure the SP network settings by using DHCP or by using a static IP address.
This section contains two alternate methods you can use to define SP network settings:
The following procedure describes how to set the SP network settings using DHCP from the Operator Panel. If your network does not use DHCP, or you want to assign a static IP address to the SP, follow the instructions in Assigning Static SP Network Settings.
1. Press any operator panel button on the server front panel (see FIGURE 2-1).
The LCD panel displays the first menu option:
FIGURE 2-1 Operator Panel Buttons
2. Press the Forward button until you reach the SP menu:
3. Press the Select button to display the SP menu options.
The following prompt appears with the default response:
5. Press the Forward button to change to Yes, then press the Select button.
6. Press the Select button at the confirmation prompt.
The server attempts to contact a DHCP server for an IP address. When the server receives a DHCP response, the LCD panel displays the DHCP-assigned SP IP addresses. The SP address is configured and the server is ready for use.
7. Continue with Creating the Initial Manager Account for instructions on creating the initial manager account.
From the operator panel, follow these steps to set the SP network settings using a static IP address. You must specify a subnet mask and default gateway. This example uses the following sample settings:
IP Address: 10.10.30.5
Subnet Mask: 255.255.255.0
Default Gateway: 10.10.30.254
1. Press any operator panel button on the server front panel (see FIGURE 2-1).
The LCD panel displays the first menu option:
2. Press the Forward operator panel button until you reach the SP menu:
3. Press the Select operator panel button to display the SP menu options.
4. Press the Select operator panel button. The following prompt displays with the default response:
5. Press the Select operator panel button.
6. With the cursor in the first field, increase or decrease the value using the Back or Forward operator panel button.
This field can hold a value between 0 and 255.
7. After reaching your desired value, press the Select operator panel button to advance the cursor to the next field.
8. Repeat Step 6 and Step 7 for each field until the desired IP address is displayed, then use the Enter button combination to save the IP Address.
The process continues to the next network setting, the Subnet Mask. The LCD displays as follows:
9. Edit the subnet mask setting in the same manner as you did for the IP address. When finished, use the Enter button combination to save the subnet mask.
The process continues to the next network setting, the default gateway. The LCD displays as follows:
10. Edit the default gateway setting in the same manner as you did for the IP address and the subnet mask. When finished, use the Enter button combination to save the default gateway.
The LCD displays the following confirmation prompt:
11. Press the Select operator panel button to use the new data, or use the Cancel button combination to disregard.
The SP address is now configured and the server is ready for use.
12. Continue with Creating the Initial Manager Account.
Creating the Initial Manager Account
After you install the server and configure the SP’s network settings, you must create the initial manager account. You can then perform initial configuration of the server and create additional user accounts. Only the administrator who does the initial system configuration can create the initial manager account.
A setup account is included with each server. This setup account has no password. When you log in to the SP the first time using the setup account, you are prompted to define the initial manager account with a password and an optional public key.
Usernames and passwords are strings that consist of any alphanumeric character, underscore, hyphen, or period.
There are two methods you can use to create the initial manager account:
Log in to the setup account and create the initial manager account by following this procedure:
1. Using an SSHv1 or SSHv2 client, connect to the IP address of the SP.
2. Authenticate as the user setup with no password required:
3. Follow the on-screen prompts to create the initial manager account.
After you create the initial manager account, the setup account is deleted and you are logged out of the server. You can then log in using the new initial manager account, from which you can create other user accounts.
After you create the initial manager account, continue with Defining a Name for the Server or Server Management and Platform Software.
To create the initial manager account from the SM Console:
1. Enter the SP name or IP address as the URL or address in a browser, to enter the SM Console.
2. At the Create Initial Manager-Level User ID screen, enter a user ID for this account.
3. Enter a password for the account.
4. Re-enter the password to confirm.
5. Click the check mark button.
6. Use the SM Console to select initial configuration options.
After you create the initial manager-level user, the Initial Configuration Checklist screen displays in the SM Console. This enables you to determine the options you want for the initial setup of the SP.
The Initial Configuration Checklist is a table that lists the SM Console menu options and the commands you use to configure each option. It also includes links to the online help that provides instructions for each option.
After you create the initial manager account, continue with Defining a Name for the Server or Server Management and Platform Software.
If desired, you can define a name for the server that will be displayed in the operator-panel LCD when the SP is idle. After you define a name, the name and the IP address of the SP alternate every few seconds in the LCD.
1. When the server is in background state, press any operator-panel button (see FIGURE 2-1).
After you press a button, the LCD panel displays the first menu option:
2. Press the Forward button until you reach the Panel menu:
3. Press the Select button to display the Panel menu options.
4. Press the Forward button until the Name for LCD menu option displays:
5. Press the Select button to enable data entry.
6. Enter an alphanumeric string to display on the first line of the LCD.
You can enter letters A through Z, digits 0 through 9, hyphen and space.
a. Use the Forward and Back buttons to locate the character you wish to enter in each field.
b. Press the Select button when you locate the character you want.
c. Repeat this process until the entire name is complete.
7. Use the Enter button combination (Forward plus Select) to save your entry.
