配置Apache支持PHP程序:

cat >>/etc/httpd/httpd.conf <<EOF
AddType application/x-httpd-php .php
AddType application/x-httpd-source-php .phps
EOF
sed -i 's/index.html/index.html index.php/g' /etc/httpd/httpd.conf
/etc/init.d/httpd restart

测试PHP:

cat >> /usr/local/httpd/htdocs/phpinfo.php <<EOF
<?php  
phpinfo();  
?> 
EOF

Apache运行模式选择prefork和worker

发布时间:May 22, 2012 // 分类:Apache // No Comments

prefork是Unix平台上默认的MPM,编译时可使用参数./configure –with-mpm=worker自定义。
查看当前MPM:

#https://www.haiyun.me
httpd -V|grep mpm
 -D APACHE_MPM_DIR="server/mpm/prefork"

prefork采用预派生子进程方式,用单独的子进程来处理不同的请求,每个进程时间内只能维持一个连接,进程之间彼此独立。
prefork配置:

<IfModule prefork.c>
ServerLimit      256 #服务器端连接数限制,最大2000
StartServers       8 #初始启动8个进程
MinSpareServers    5 #最小空闲进程数
MaxSpareServers   20 #最大空闲进程数,超过限制父进程将杀死多余的子进程。
MaxClients       256 #最大连接、进程数,一般和ServerLimit相同,超过此限制的请求进入等候队列。
MaxRequestsPerChild  4000 #每个进程生存期间可处理请求次数,超过终结此进程。
</IfModule>

worker支持多线程和多进程混合模型的MPM,使用多线程来处理,可以处理相对大量的请求,而系统资源的开销要小于基于prefork的服务器。
worker配置:

<IfModule worker.c>
StartServers         10 #默认启动子进程数
MaxClients         150 #同一时间最大连接数
MinSpareThreads     25 #最小空闲线程数
MaxSpareThreads     75 #最大空闲线程数
ThreadsPerChild     25 #每个进程建立的常驻线程数
MaxRequestsPerChild  40000 #每个进程生存期间可处理请求次数,超过终结此进程。
</IfModule>

Linux下清除登录记录及历史命令

发布时间:May 22, 2012 // 分类:Linux基础 // No Comments

查看历史登录记录:

last
utmpdump /var/log/btmp

清除历史登录记录:

echo > /var/log/wtmp

查看失败登录记录:

lastb
utmpdump /var/log/btmp

清除失败登录记录:

echo > /var/log/btmp

清除历史命令:

history -c
echo > ~/.bash_history 

inotify配合rsync实时同步备份服务器数据

发布时间:May 21, 2012 // 分类:备份存储 // No Comments

主服务器需安装配置inotify-tools,用于实时监控服务器文件变化。
inotify-tool实时监控并发送文件到rsync从服务器脚本:

#/bin/bash
host=https://www.haiyun.me
src=/var/www/html
dst=www
user=back
passwd=passwd
echo "$passwd" > /etc/rsync.pass
chmod 600 /etc/rsync.pass
inotifywait -mrq -e close_write,create,delete,attrib --timefmt '%d/%m/%y %H:%M' --format '%T %w%f %e' $src\
|while read files 
do
    file=`echo $files|awk '{print $3}'`
    rsync -vzrtopg --delete --progress $file $user@$host::$dst --password-file=/etc/rsync.pass
    echo "$files was rsynced" >> /var/log/rsync.log
done

从服务器配置rsync:

uid = nobody
gid = nobody
use chroot = no
max connections = 10
strict modes = yes
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsyncd.lock

[www]
path = /home/wwwroot
comment = www file
ignore errors
hosts allow = *
list = false
auth users = onovps
secrets file = /etc/server.pass
read only = no
write only = no
uid = root
gid = root

建立验证文件,root权限可查看:

echo "onovps:passwd" > /etc/server.pass 
chmod 600 /etc/server.pass

启动rsync进程:

rsync --daemon
echo "rsync --daemon" >> /etc/rc.local

tar打包排除指定目录无效解决

发布时间:May 20, 2012 // 分类:Linux基础 // No Comments

用tar打包备份时使用tar exclude排除指定目录,测试了很多次都不成功,正确的用法是:

tar zcv -f etc.tar.gz /etc  --exclude=/etc/passwd --exclude=/etc/sysconfig

打包的目录和排除的目录后都不要带/号,否则排除目录无效。
