Using DNS Server domain name resolution for simple polling, two httpd servers for simple load balancing. NFS acts as the root directory for site resources. Two httpd share a MySQL service store

The same method installs another httpd+php on the same host but changes the apache1 to apache2 php1 PhP2 Note When installing Apache2 on the same host , Apr and apr-util To reinstall a copy, the second host cannot start the listening process .

In addition, to edit the vim/etc/apache2/httpd.conf Monitor the second NIC port such as:

At this point, the MARIADB installation succeeds to create an NFS share: Vim/etc/exports content is as follows: The shared directory creates a directory for/myweb Mkdir/myweb

Put the Discuz installation file upload into this directory and modify the permissions because Apache runs daemon user so chown-r daemon:daemon/mywebchmod-r 755/mywebnfs and installation files will accompany. Create the database for the installation site Mysql-uroot-p-E "Create databse myweb" Mysql-uroot-p-E "Grant all on myweb.* to ' myweb ' @ ' 172.16.101.35 ' IDE Ntified by ' hzm132 ' "Mysql-uroot-p-E" Grant all on myweb.*-' myweb ' @ ' 172.16.101.36 ' identified by ' hzm132 ' "Mysql-uroo T-p-E "flush privileges" view

Okay, the data is ready.

Now to the Apache server hangs the NFS shared files to the site root directory

Mount-t NFS 172.16.101.100:/myweb/usr/local/apache2/htdocs/

Mount-t NFS 172.16.101.100:/myweb/usr/local/apache1/htdocs/

Start the installation process select any host can install the process no longer repeat details refer to the previous blog

Test:

Upload data is accessible via any host
