五一最好的哥们结婚了，真心的祝福，婚礼很成功，洞房闹的也不错。希望你们两口子永远幸福。

今天早上回想了一下，好像离开北京要满两年了，两年里发生了好多好多事，准确的说是有点迷迷糊糊的过了两年，没有时间可以去被浪费了。要努力了。加油吧，迎接新的挑战。

ubuntu安装mrtg手记

Raselion — Sat, 03 Dec 2011 03:22:55 +0000

因为需要，需要监控下网络环境，试着安装了一下mrtg，ubuntu虽然安装简单，但也遇到了一点小波折。

安装软件：
apt-get install apache2
apt-get install mrtg
apt-get install snmpd

编辑snmpd：
vim /etc/snmp/snmpd.conf

查找到类似的行，修改为如下所示：（仅仅修改屏蔽或放开）
# sec.name source community
# com2sec paranoid default public # kommentieren
com2sec readonly default public # <- auskommentieren
#com2sec readwrite default private

重启snmpd服务：
/etc/init.d/snmpd restart

重新生成mrtg的配置文件：
cfgmaker public@localhost > /etc/mrtg.cfg

（注意）如果仅仅监视一个IP地址采用如下命令：
cfgmaker public@192.168.0.1 >> /etc/mrtg.cfg

生成mrtg的主页：
indexmaker /etc/mrtg.cfg > /var/www/mrtg/index.html

访问：

http://localhost/mrtg/

一般来说上面的步骤不会有一点问题，但有的时候会出现“Use of uninitialized value $first in hash element at /usr/bin/indexmaker line 353.”的错误。

这个错误呢一般是由于mrtg模板问题造成的，下面发一个我改的模板上来

# Created by

数据库自动备份脚本并传输到远程服务器

Raselion — Tue, 08 Nov 2011 15:38:58 +0000

公司网站需要实现自动备份数据库并且要传送到另外一台服务器以方便数据保存，折腾了半个晚上，终于解决。

下面的是数据库服务器要存放的脚本：

#! /bin/bash

echo "Weiqp.cn Database Backup Mysql V1.0"

###date stamp###
datestamp=$(date +%Y-%m-%d)

###path ###
startdir=/home/mysqlbackup

###bakfile prefix###
fileprefix=fiename
echo "Datebase backup is starting.."

###bakup command####
mysqldump -u root -ppassword -l dbname > $startdir/$fileprefix$datestamp.sql

echo "########################################################################"

#echo "Datebase backup successfully."

###tar file ###
cd $startdir

echo "the current directory is :"
pwd

tar zcvf $startdir/$fileprefix$datestamp.tgz $fileprefix$datestamp.sql
###del the sql file###
rm -rf $startdir/$fileprefix$datestamp.sql

echo "#######################################################################"

echo "Backup File Save successfully."

下面的是远程都去备份文件的脚本：

#! /bin/bash
echo "Weiqp.cn Datebase Backup For mysql V1.0"
datestamp=$(date +%Y-%m-%d)
firstname=filename
cd /home/mysqlbackup
wget http://dbbackup.server.com/$firstname$datestamp.tgz
cd ..
echo "Backup File Download Successfully."

这个远程下载脚本，网上有很都使用ssh来传送这个备份，但我在私钥的地方卡了两个小时也没有解决shh自动登陆的问题所以采用了用http方式来更新备份文件

剩下的就是执行自动执行脚本了。

在crontab下按照自己需要的规则来执行脚本就可以了。

vim /etc/crontab

25 23 * * * root sh /home/getDb.sh

我是在每天晚上11点25分开始备份数据库，可以根据自己的需求更改频率跟时间。

Strong tropical storm” nig” hit Hainan Taiwan Joan Guangdong a dangerous situation

huli — Mon, 03 Oct 2011 13:11:37 +0000

News agency Beijing, October 3 report ( reporter Ruan Yulin ) strong tropical storm,” negore” taken into China and Hainan, is expected to be 4 in the morning to noon in Hainan Sanya to Wanning along the coastal areas or from southern Sanya offshore through, and will be in Taiwan, Guangdong, Hainan and other coastal set off a dangerous situation.

The Central Meteorological Station issued 3 typhoon yellow early warning, the nineteenth this year, strong tropical storm,” negore” center 3 days 17 when located in Hainan province Lingshui County East about 360 kilometers south of the South China Sea, near the center of the largest wind 11. Expected,” negore” will be 15 km per hour speed to continue moving to the west, to the Southeast Hainan coast, and from 4 noon to evening in Hainan Wanning to Sanya along the coastal areas or through southern Hainan offshore continued westbound.

China Meteorological Bureau of public weather service meteorologists Duan Li said when accepting a reporter to interview, September 27th, tropical storm” Begonia” in Vietnam Guang Zhisheng coastal landfall; September 29th, the strong typhoon “Na Sha ” landing Hainan Wenchang and Guangdong Cape Xuwen tail rural coastal areas of the two landing. “Na Sha” is not far away,” negore” has been carrying the wind rain to Hainan.

The meteorological expert indicated that, compared with “Na Sha”,” negore” landing when the strength is expected to be a strong tropical storm, although the “Na Sha”,” negore” brings to Hainan storm of small effect, brought to Hainan the influence of wind and rain will be concentrated in the Southeast region. But Hainan a short time successively encounters” Begonia”, “Na Sha”,” negore” three typhoon, disaster prevention pressure still nots allow small gaze.

The central meteorological station is expected,” negore” and cold air joint influences, 3 day 20 when to 4 days 20 when, most of the East China Sea, the Taiwan Strait, northern South China Sea, Zhejiang, Fujian and central coast coastal, coastal Taiwan, Guangdong coastal areas and the Pearl River Estuary, coastal Guangxi, Hainan coast, the Qiongzhou Strait, Northern Bay will have 7 to 9 levels of gales,” negore” center through the waters near or region will have 10 to 11 winds, wind gusts up to grade 12-13; Hainan, western Guangdong coastal, Eastern Taiwan and other places will have heavy rain, rainfall is 40-70 mm, wherein, parts of southeastern Hainan is big heavy rainfall, rainfall is 100-200 mm.

In order to effectively cope with the strong tropical storm,” negore” brings the influence of wind and rain, the China Meteorological Administration, 3 to start the major meteorological disaster and emergency response.

新岗位2

Raselion — Tue, 27 Sep 2011 15:05:11 +0000

到了新岗位一个星期了，总体来说压力山大啊，开始的几天快速的解决了几个问题，但在昨天开始遇到了很棘手的问题，整体规划和实施方案，这个有点超出我的范围了，整个机房技术对我来说是完全陌生的，交换机，防火墙都是之前没接触过的。。并且这个星期做了一个到这个公司第一个开除人的决定，虽然很不情愿，但真的没有办法啊。周四开始做网络割接了，希望顺利，希望可以搞定交换机。十一别出事，安安稳稳的过个假期吧。

discuz x2管理员无法登陆的解决方法

Raselion — Tue, 27 Sep 2011 14:47:32 +0000

新安装的Discuz! X2，
在添加一个新用户并设置为管理员后，无法登录后台“管理中心”，并且无任何错误提示。
解决方法如下：

1. 用创始人账户新建一帐户，并添加到管理员组。

2. 将bbs_common_member表中该用户的allowadmincp字段设置为1。

3. 修改config/config_global.php文件，将该用户的ID添加到创始人里面：

// ————————– CONFIG ADMINCP ————————– //
// ——– Founders: $_config['admincp']['founder'] = ’1,2,3′; ——— //

$_config['admincp']['founder'] = ’1,newid’;

通过这个方法我是顺利解决了，网上其他方法都无效。。

新岗位第一天

Raselion — Wed, 21 Sep 2011 01:33:28 +0000

接手的第一天上午基本是没做什么事情，主要是在看，看每个人的工作状态，看每个人的工作态度，总体来说不是很满意，需要调动起来积极性和协调每个人的工作。并且确立汇报制度。并且开始整合机房等部门，还要增加一个库管的职位。

新工作的第一天，忙的头大。不过进度有所增加，挺好，争取一个月内可以走流程，而不是看人干活。

Come on，Go，Go。

xen server 之路

两个月了，思杰的xenserver在我的测试下跑了俩月了。目前遇到了，整个柜子白屏死机，还有主板会出现无法格式化硬盘的问题，暂时只知道，主板不放到机箱里就不会有问题，放进机箱里就会出现问题，目前无解，还有，那个鸟交换机，完全不明白，难受啊。。

新的挑战

又长草了，很久没写博客了。前段日子太忙，大部分时间都是忙着新公司的事情，看着一个在自己管理下的从带着实习生开始，逐渐的完善起来，到现在可以做一般的简单网站项目，真的是很欣慰，明天开始，要进入新的团队了，整合整个公司机房技术团队。难度好大，计算机所有领域里，最不熟悉的就是网络了，xenserver，交换机，都不是很明白。还要整合公司几个位置的人来，难度不小啊。。加油努力，明天开始写一个技术主管的日志吧，希望可以

之前一直都是用ubuntu来做服务器，但现在的机器都是centos了，还得重新学习下.下面是安装记录.

1. 安装Apahce, PHP,以及php连接mysql库组件。
yum -y install httpd php php-mysql

2. 配置开机启动服务
/sbin/chkconfig httpd on             [设置apache服务器httpd服务开机启动]
/sbin/chkconfig –add mysqld         [在服务清单中添加mysql服务]
/sbin/chkconfig mysqld on             [设置mysql服务开机启动]
/sbin/service httpd start             [启动httpd服务,与开机启动无关]

3.
//安装apache扩展
yum -y install httpd-manual mod_ssl mod_perl mod_auth_mysql
//安装php的扩展
yum install php-gd
yum -y install php-gd php-xml php-mbstring php-ldap php-pear php-xmlrpc

4.apache的配置文件是/etc/httpd/conf下
modules放在/usr/lib/httpd下
php的配置文件在/etc/php.d/下和/etc/php.ini
php的modules放在/usr/lib/php/modules下

apache 默认支持php
