Отказоустойчивый сервер для хостинга сайтов


Инсталляция Apache



[root@server1 ~]# yum install -y httpd && ssh server2 yum install -y httpd
[root@server1 ~]# chkconfig --level 345 httpd on && ssh server2 chkconfig --level 345 httpd on


[root@server1 ~]# cp /etc/httpd/conf/httpd.conf /etc/httpd/conf/httpd.conf.orig && ssh server2 cp /etc/httpd/conf/httpd.conf /etc/httpd/conf/httpd.conf.orig

[root@server1 ~]# vi /etc/httpd/conf/httpd.conf Добавляю в блок userdir: <IfModule mod_userdir.c> UserDir disabled UserDir enabled hoster UserDir public_html <Directory /home/*/public_html> AllowOverride FileInfo AuthConfig Limit Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec <Limit GET POST OPTIONS> Order allow,deny Allow from all </Limit> <LimitExcept GET POST OPTIONS> Order deny,allow Deny from all </LimitExcept> </Directory>


Разрешено использовать userdir только для пользователя hoster

[root@server1 ~]# scp /etc/httpd/conf/httpd.conf server2:/etc/httpd/conf/httpd.conf


[root@server1 ~]# service httpd restart && ssh server2 service httpd restart 

Создание пользователя hoster на обоих узлах с uid 10001


[root@server1 ~]# useradd \
-d /home/hoster \
-m hoster \
-u 10001

[root@server1 ~]# passwd hoster



[root@server1 ~]# su - hoster

[hoster@server1 ~]$ mkdir public_html
[hoster@server1 ~]$ cd public_html/
[hoster@server1 ~]$ vi index.html


http://192.168.1.21/~hoster/
ok



[root@server1 ~]# ssh server2

# useradd \
-d /home/hoster \
-m hoster \
-u 10001







Инсталляция ftp сервера


[root@server1 ~]# rpm -ivh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
[root@server1 ~]# ssh server2 rpm -ivh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

[root@server1 ~]# yum install -y proftpd && ssh server2 yum install -y proftpd
[root@server1 ~]# chkconfig --level 345 proftpd on && ssh server2 chkconfig --level 345 proftpd on

[root@server1 ~]# service proftpd restart && ssh server2 service proftpd restart


Инсталляция xinetd и rsync

[root@server1 ~]# yum install -y xinetd && ssh server2 yum install -y xinetd
[root@server1 ~]# chkconfig --level 345 xinetd on && ssh server2 chkconfig --level 345 xinetd on


[root@server1 ~]# yum install -y rsync && ssh server2 yum install -y rsync


[root@server1 ~]# vi /etc/xinetd.d/rsync

меняем
disable = yes
на 
disable = no


[root@server1 ~]# scp /etc/xinetd.d/rsync server2:/etc/xinetd.d/rsync

[root@server1 ~]# service xinetd restart && ssh server2 service xinetd restart

Убеждаемся, что xinetd слушает rsync
[root@server1 ~]# netstat -lnpt | grep 873

[root@server1 ~]# ssh server2

[root@server2 ~]# vi /etc/rsyncd.conf

pid file = /var/run/rsyncd.pid

[home]
        uid = root
        use chroot = yes
        path = /home
        read only = no
        hosts allow = server1.localdomain


CTRL + D

[root@server1 ~]# rsync server2::
home  

[root@server1 ~]# rsync server2::home
drwxr-xr-x        4096 2014/01/31 23:40:39 .
drwx------        4096 2014/01/31 23:42:19 hoster
drwxr-xr-x        4096 2013/03/10 05:11:09 projects


[root@server1 ~]# rsync -av --delete /home/ server2::home
