wordpress open_basedir restriction in effect问题

C1G — Wed, 28 Jul 2010 06:19:22 +0000

nginx-0.8.46
php-5.2.14
mysql-5.1.37
eaccelerator-0.9.6.1
wordpress 为官方3.0英文版

安装后在页面出现错误信息

Warning: require() [function.require]: open_basedir restriction in effect. File() is not within the allowed path(s): (/opt/htdocs:/opt/lampp/htdocs:/opt/php/lib/php:/tmp/session:/tmp/upload) in /opt/lampp/htdocs/wordpress/wp-settings.php on line 132

php.ini 中的配置也没错

open_basedir = "/opt/htdocs:/opt/lampp/htdocs:/opt/php/lib/php:/tmp/session:/tmp/upload"

关闭open_basedir或去掉[eaccelerator]之后不会报错，安全起见open_basedir一定要开，eaccelerator换成0.9.5.3后没问题了。

tar jxvf eaccelerator-0.9.5.3.tar.bz2
cd eaccelerator-0.9.5.3/
/opt/php/bin/phpize
./configure --enable-eaccelerator=shared --with-php-config=/opt/php/bin/php-config
make
make install

在输入密码后就断掉了，把机器重启下后，可以登录了。

查看/var/log/messages 和 /var/log/cron
发现从凌晨3点起就没有记录了，估计是磁盘出错变成不可写适成不能登录。

RRDtool 1.4.4 安装

C1G — Thu, 22 Jul 2010 03:59:29 +0000

RRDtool介绍

RRDTool是由Tobias Oetiker开发的自由软件，它使用RRD（Round Robin Database）作为存储格式，Round robin是一种处理定量数据、以及当前元素指针的技术。RRDTool主要用来跟踪对象的变化情况，生成这些变化的走势图。

07/09/10释放的cacti-0.8.7g已支持rrdtool-1.4X

cacti 监控远程主机

C1G — Wed, 21 Jul 2010 03:47:02 +0000

环境介绍
安装cacti的监控机A,ip为 192.168.0.16
安装snmp的被监控机B,ip为 192.168.0.17
系统为centos 4/5

被监控B机安装snmp
net-snmp 安装参考

修改B机snmp配置，充许外部访问
自带的snmp配置文件在/etc/snmp/snmpd.conf;
编译安装的snmp配置文件在/usr/local/etc/snmp/snmpd.conf;
vi /etc/snmp/snmpd.conf

com2sec local localhost privatepass #安装教程中配置的本机访问要权限
com2sec mynetwork 192.168.0.16 privatepass #新增的外部访问权限，192.168.0.16为监控机ip,privatepass 为安全码可以和local不同
group MyROGroup v1 local
group MyROGroup v2c local
group MyROGroupnet v1 mynetwork #新增
group MyROGroupnet v2c mynetwork #新增
view mib2 included .iso.org.dod.internet.mgmt.mib-2 fc
view all included .1 80 #新增
access MyROGroup "" any noauth exact mib2 none none
access MyROGroupnet "" any noauth exact all none none #新增
#以下为访问项目，如果想监控磁盘空间，load等需把注释去掉
#编译安装默认已去掉，自带安装的需手动把注释去掉
# Make sure mountd is running
proc mountd #去掉前面的"#"
# Make sure there are no more than 4 ntalkds running, but 0 is ok too.
proc ntalkd 4
# Make sure at least one sendmail, but less than or equal to 10 are running.
proc sendmail 10 1
# Check the / partition and make sure it contains at least 10 megs.
disk / 10000
# Check for loads:
load 12 14 14

重启snmpd服务
#/etc/init.d/snmpd restart
或
#killall -9 snmpd
#/usr/local/sbin/snmpd

iptables规则
假如B机开启了iptables并且INPUT默认策略为DROP
在第一条插入充许192.168.0.16(监控机)以udp协议访问snmpd默认161端口的规则

/sbin/iptables -I INPUT -p udp -m udp -s 192.168.0.16 --dport 161 -j ACCEPT

保存一下,防止重启服务后失效

/etc/init.d/iptables save

测试snmp
在A机上先看下系统信息

".1.3.6.1.4.1.2021.9"代表磁盘
".1.3.6.1.4.1.2021.10"代表load,可以参考snmpd.conf中的注释

监控机cacti增加监控设备
Console -> Devices->add

在设置页面配置

Description:touareg
Hostname:192.168.0.17
Host Template:ucd/net SNMP Host

Downed Device Detection:Ping and SNMP

SNMP Version:预定义的设置

保存后在页面左上角可以看到调试信息

touareg (192.168.0.17)

1) ucd/net - CPU Usage Not Being Graphed (cpu负载,system,user,nice)
2) ucd/net - Load Average Not Being Graphed (系统平均负载,1分钟,5分钟,15分钟)
3) ucd/net - Memory Usage Not Being Graphed (内存使用,free,buffers,cache)

1) SNMP - Interface Statistics (网卡流量,in,out)
2) ucd/net - Get Monitored Partitions (根分区,free,used)

Not Being Graphed 表示还末生成图像,创建图像后会变成Is Being Graphed
我们可以再添加一些更详细的监控
Host MIB - Processes 监控进程数量
Host MIB - Logged in Users 监控登录用户

SNMP - Get Mounted Partitions 更多分区大小,Memory Buffer,Real Memory,Swap Space
SNMP - Get Processor Information 每个cpu的负载

临控对像增加图表
左则New Graphs
在host中选择touareg

勾选右则后选择create,就完成了图表创建，真是很方便。

添加到Graph Trees
图表创建后在Graph Management里可以看到图表，但点击导航上方的"graphs"是看不到的，需要添加到graph trees中。
Console -> Graph Trees -> (Edit) -> Graph Tree Items

Tree Item Type:host
Host:touareg

创建后就可以在graph中看到了

在 Android 手机上运行 PHP

C1G — Fri, 16 Jul 2010 08:56:19 +0000

PHP可不仅仅只能在互联网站上发展，一个PHP for Android (PFA)网站表示他们将可以发布编程模型、工具盒文档让PHP在Android上实现应用。该项目的主要赞助商是开源公司IronTec，PFA使用Scripting Layer for Android (SL4A)，也就是Androd Scripting Environment (ASE)来实现这一点，您可以参看他们的网站来了解更多技术内幕。

1.下载并安装ASE
扫描下面的二维码,可在你的手机上安装个条码扫描器(BarcodeScanner)

或用浏览器下载并安装
http://phpforandroid.net/files/ASEr26unofficial.apk

2.安装PhpForAndroid.apk

或用浏览器下载并安装
http://phpforandroid.net/files/PhpForAndroid_r1.apk

3.运行
安装好PhpForAndroid_r1.apk后再运行ASE就可以看到5个php demo
hello_world.php

require_once("Android.php");
$droid = new Android();
$name = $droid->getInput("Hi!", "What is your name?");
$droid->makeToast('Hello, ' . $name['result']);

list_items.php

require_once("Android.php");
$droid = new Android();
$droid->dialogCreateAlert();
$droid->dialogSetItems(range(0, 9));
$droid->dialogShow();

phpinfo.php

require_once("Android.php");
... phpinfo（）;#这里是我编辑器问题改成了全角

testnow.php

require_once("Android.php");

cacti 安装npc 整合 nagios

C1G — Thu, 15 Jul 2010 08:19:02 +0000

Cacti是一套PHP程序，它使用snmpget命令采集数据、RRDTool绘图。Cacti界面简洁直观，让你根本无需明白RRDTool的众多参数即可轻松绘制出漂亮的图形。另外，它还提供了强大的数据管理和用户管理功能。在图像管理上，Cacti采用了树状结构的查看界面，在用户管理上，能对用户的权限进行细致划分，甚至支持使用LDAP进行用户验证。Cacti主要功能包括：数据定时采集、图像绘制与显示、树状的主机和图像管理、RRDTool信息管理、用户和权限管理以及模板导入导出等。

1.Cacti系统组成

　　Cacti系统由4个部分组成：

　　Cacti页面(PHP)——用户控制的平台，用户在此进行所有的设置；

　　SNMP采集工具——Unix下使用 Net-SNMP软件包自带的“snmpget”和“snmpwalk”等程序，Windows下使用PHP的SNMP功能；

　　RRDTool绘图引擎——性能数据的存储和绘画图像；

　　MySQL数据库——储存RRDTool绘图所需的信息，如模板、rra、主机对应的信息等，要注意的是MySQL数据库并不保存性能数据，性能数据保存在RRDTool自己的数据库格式rrd文件中。利用Cacti可以对校园网络进行很好的实时监控，从而做到运筹帷幄。
2.菜单功能介绍

　　Console菜单包括了New Graphs(创建新图像)、Graph Management(图像管理)、Graph Trees(图像树)、Data Sources(管理rrd文件)、Devices(设备管理)、 Data Queries 和Data Input Methods(采集数据方式)、Graph Templates(图像模板)、Host Templates(主机类型模板)、Data Templates(数据模板)、Import Templates(模板导入)、Export Templates(模板导出)Settings(Cacti的主要配置菜单)、System Utilities(显示Cacti系统的一些cache和log信息)、User Management(用户管理)、Logout User (用户退出登录)等菜单选项。

　　Grapes菜单包括三种查看图像的形式，分别为setting、树形显示、列表型显示和预览型显示。

在线demo:
http://status.pulpfree.org/cacti/graph_view.php?action=tree&tree_id=3&leaf_id=28&select_first=true
http://www.querx.com/cacti/graph_view.php?action=tree&tree_id=1&leaf_id=9
http://www.kende.com/cacti/graph_view.php?action=tree&tree_id=1&leaf_id=7&select_first=true
更多demo:
http://www.cacti.net/sites_that_use_cacti.php

最新版本:
The latest stable version is 0.8.7g, released 07/09/10.
http://www.cacti.net/download_cacti.php
0.8.7g版本和某些插件有兼容型问题，如npc,thold，我安装下来在顶部不能正常显示导航菜单。
cacti的版本要和插件架构匹配，我装0.8.7e+cacti-plugin-0.8.7f-PA可以使用，但顶部导航显示不正确。
这里选用0.8.7e+cacti-plugin-0.8.7e-PA

依赖关系：
安装之前需lamp环境安装参考
net-snmp 安装参考
RRDTool 安装参考
php扩展安装参考
php_json
pdo_mysql
sockets
nagios 安装参考
ndoutils 安装参考

下载cacti：
cd /opt/htdocs/www
wget wget http://www.cacti.net/downloads/cacti-0.8.7e.tar.gz
wget http://mirror.cactiusers.org/downloads/plugins/cacti-plugin-0.8.7e-PA-v2.6.zip
wget http://www.constructaegis.com/downloads/npc-2.0.4.tar.gz

constructaegis.com域名已过期
可以使用svn checkout
http://svn2.assembla.com/svn/npc/trunk

安装cacti:
我的nginx运行用户为www组为website
安装路径为/opt/htdocs/www

tar zxvf cacti-0.8.7e.tar.gz
mv cacti-0.8.7e cacti
chown -R www:website cacti
chmod -R 0775 cacti

安装cacti数据库:
创建cacti库,并创建cacti用户给予它cacti库权限,也可以使用phpmyadmin来完成.
导入cacti.sql到cacti库

mysql –u root –p
mysql>create database cacti;
mysql>use cacti;
Mysql>source /opt/htdocs/www/cacti/cacti.sql
Mysql>grant all privileges on cacti.* to cacti@localhost identified by ‘cactipass’;
#添加一个数据库账号cacti 密码为cactipass 用以访问cacti库
Mysql>flush privileges; #刷新权限信息

配置cacti数据库信息
#cd cacti
#vi include/config.php

$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cactiuser";
$database_password = "cacti";

配置cacti自动运行:
#crontab -e

*/5 * * * * /opt/php/bin/php /opt/htdocs/www/cacti/poller.php > /dev/null 2>&1

Spine更有效率可以选择性安装

配置cacti:
访问cacti的web地址，就会显示安装界面
http://nagios.c1gstudio.com/cacti/

1.选择"新的安装"

2.配置路径(以系统中实际安装路径为准)
/usr/local/rrdtool/bin/rrdtool
/opt/php/bin/php
/usr/local/bin/snmpwalk
/usr/local/bin/snmpget
/usr/local/bin/snmpbulkwalk
/usr/local/bin/snmpgetnext

3.默认用户名及密码
admin/admin
接着输入新的密码

4.进入cacti后台
设置相应版本及验证码
settings->General
RRDTool Utility Version = RRDTool1.3.X
SNMP Version = 2
SNMP Community = 你的验证码(privatepass )
save

5.查看报表
点graphs选项5分钟后应该可以看到4个报表.
memory usage
load average
logged in users
processers

6.创建磁盘监控
在首页点击Create graphs然后在Data Query栏目中勾上需要监控的分区保存.

以上完成了cacti安装，下面安装插件
在安装插件前需先安装"插件框架"

安装插件框架:
1.解压

cd /opt/htdocs/www
unzip cacti-plugin-0.8.7e-PA-v2.6.zip
chown -R www:website cacti-plugin-arch/
chmod -R 0775 cacti-plugin-arch

2.导入数据库结构

mysql -u cacti -p cacti

3.覆盖文件
方法一:覆盖

cp –rf cacti-plugin-arch/files-0.8.7e/* /opt/htdocs/www/cacti

方法二:打补丁

cp cacti-plugin-arch/cacti-plugin-0.8.7e-PA-v2.6.diff /opt/htdocs/www/cacti/
cd /opt/htdocs/www/cacti/
patch -p1 -N

我用方法一

4.配置插件的数据库信息
#cd /opt/htdocs/www/cacti/
#vi include/global.php
#插件数据库需再配置一下

$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cactiuser";
$database_password = "cacti";

5.配制插件

#我的cacti安装在域下的cacti目录，这里也需修改
$config['url_path'] = '/cacti/';
#为后面安装npc增加变量
$plugins[] = 'npc';

注:0.8.7g开始上面两变量改放在includes/config.php中，如果参照以前的教程会找不到了囧
参见Change Log
http://forums.cacti.net/viewtopic.php?t=38492

安装NPC插件:
1.解压后移到plugins目录下

cd /opt/htdocs/www
unzip npc.zip
chown -R www:website npc
chmod -R 0775 npc
mv npc cacti/plugins/

2.启用cacti的插件功能，
以admin用户登陆cacti，在console中的user management里对admin的用户权限进行编辑，
勾选上Plugin Management、NPC、NPC Global Commands
然后到Plugin Management
安装并启用NPC即可。
在Settings->npc中
勾上Remote Commands
Nagios Command File Path=/usr/local/nagios/var/rw/nagios.cmd
Nagios URL=你的地址(http://nagios.c1gstudio.com/nagios/)

3.配置ndoutils
参见

如果一切正常点击导航菜单npc后就可以看到信息了。
没有显示可能有以下原因：

cacti和npc版本不兼容
cacti和plugin框架版本不一致
npc没有正确安装(数据库结构不对)
ndoutils没有正确配置(数据库中无信息)
php-json,pdo_mysql,sockets没有安装(php -m 检查一下)

lvm在线增加磁盘空间

C1G — Mon, 05 Jul 2010 04:25:29 +0000

一。查看当前空间
#df -h

Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
97G 1.9G 91G 3% /
/dev/mapper/VolGroup00-LogVol01
194G 140G 44G 77% /home
/dev/mapper/VolGroup00-LogVol04
97G 17G 75G 19% /var
/dev/mapper/VolGroup00-LogVol03
97G 52G 41G 56% /opt
/dev/mapper/VolGroup00-LogVol02
9.7G 158M 9.1G 2% /tmp
/dev/sda1 99M 12M 82M 13% /boot
tmpfs 1010M 4.0K 1010M 1% /dev/shm

/home 增加200G
/opt 增加100G

fdisk 查看下磁盘为1T大小,并全部分给lvm
#fdisk -l

Disk /dev/sda: 1000.2 GB, 1000203804160 bytes
255 heads, 63 sectors/track, 121601 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/sda3 536 121601 972462645 8e Linux LVM

vgdisplay查看卷组空间,还有400G空闲空间
#vgdisplay

Free PE / Size 13357 / 417.41 GB
VG UUID 4Wzdqp-f3RH-1lEP-YfXN-01Vp-3K5c-EmtcBE

二.开始增加空间
(错误的方式)
#lvextend -L +100G /dev/mapper/VolGroup00-LogVol03

Volume group "mapper" not found
Volume group mapper doesn't exist

这里的设备名写错了(另注意一定要加"+")，正确的是
#lvextend -L +100G /dev/VolGroup00/LogVol03

Extending logical volume LogVol03 to 200.00 GB
Logical volume LogVol03 successfully resized

三.lvextend修改了lvm的大小，下面还需修改文件系统大小。
可以用umount+resize2fs 或ext2online
umount通常会碰到device is busy，这里用ext2online

下载ext2online
http://www.mirrorservice.org/sites/download.sourceforge.net/pub/sourceforge/e/project/ex/ext2resize/ext2resize/ext2resize-1.1.19/

1.下载i386的rpm
#wget http://www.mirrorservice.org/sites/download.sourceforge.net/pub/sourceforge/e/project/ex/ext2resize/ext2resize/ext2resize-1.1.19/ext2resize-1.1.19-1.i386.rpm

2.创建sct用户
#useradd sct
#rpm -ivh ext2resize-1.1.19-1.i386.rpm
-----------------
安装完成后会有三个命令：
ext2online ext2prepare ext2resize
-----------------
注意：安装此工具，必须有sct用户(当前用户不用是sct)

3.运行
#ext2online /dev/VolGroup00/LogVol03
ext2online v1.1.18 - 2001/03/18 for EXT2FS 0.5b

四.最后检查
#df -h

Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
97G 1.9G 91G 3% /
/dev/mapper/VolGroup00-LogVol01
194G 140G 44G 77% /home
/dev/mapper/VolGroup00-LogVol04
97G 17G 75G 19% /var
/dev/mapper/VolGroup00-LogVol03
194G 52G 133G 28% /opt
/dev/mapper/VolGroup00-LogVol02
9.7G 158M 9.1G 2% /tmp
/dev/sda1 99M 12M 82M 13% /boot
tmpfs 1010M 0 1010M 0% /dev/shm

/opt 已增加到200G.同样的方式再增加/home就可以了。
