8 THE SURVIVAL OF THE FITTEST 8

9 Chapter 1. SHARED HOSTING 9

10 NOT ALL HOSTINGS ARE THE SAME Requirements: some Linux Apache PHP MySQL FTP SSH access Unlimited everything Disk Transfer Domains Databases Users 10

11 HITTING THE WALL The limits CPU Memory Database Caching (APC, opcache) Extra PHP stuff (uploadprogress, xdebug) Tweaks 11

12 DREAMHOST: LOVE & HATE Tuned: Users: unlimited! Memory:.htaccess raised! Database: horor, hell. Caching (APC, opcache) added! Extra PHP stuff added! (uploadprogress, xdebug) Tweaks totally customized :D 12

13 Chapter 2. EVALUATING DRUPAL HOSTING OPTIONS 13

14 ASSUME NOTHING My favourite 8086 assembler directive 14

15 IMPORTANT QUESTIONS Who you are? Service or VPS? Who your clients are? Service or VPS? System skill level Will you be able to cope with system maintaining Resources needed Service or VPS? Sites Memory CPU Disk Transfer SSL IP Budget Client expectations, sensitivity Security, maintenance, performance World region Proximity to client market 15

16 Chapter 3. TESTING FOR VPS 16

17 AWS FREE TIER MICRO INSTANCE EC2 t2.micro: 1 CPU 1 GB 30 GB of EBS World region Spot vs Reserved Load balancing 17

18 Chapter 4. BUILDING THE VPS 18

19 $10 = 1 CPU, 1GB, 30GB Cheaper plan is just too small. 1GB is enough for moderate use but will not allow Solr and memory use will be ~ MB active 2GB would raise MySQL cache, allow for Solr (~200MB) and leave some room for more performance. 4GB is expensive -> Dedicated 19

20 INSTANCE BUILD: DEBIAN 7 32BIT Debian: 6 or 7 Ubuntu CentOS FreeBSD Darwin/Mac? some exotic? 32 bit No need for less than 4GB 64 bit Imperative if you have more than 4GB 20

21 SUPPORTED LTS OS 32/64BIT MINIMAL ON SERVER OR DESKTOP ON LOCALHOST Debian 7 Wheezy (recommended) Debian 6 Squeeze (fully supported with automatic upgrade to Wheezy available) Ubuntu Trusty (limited support) Ubuntu Precise (limited support) Ubuntu Lucid (limited support) 21

25 REQUIREMENTS FOR BOA wget must be installed. The git standard port 9418 must be open. SMTP standard port 25 (or SMTP relay) must be open for outgoing connections. Minimum 1 GB of RAM Locales with UTF-8 support, otherwise en_us.utf-8 (default) is forced. Basic sysadmin skills and experience. Willingness to accept BOA PI (paranoid idiosyncrasies). 25

26 BOA INSTALLATION IMPORTANT! Don't run any installer via sudo. You must be logged in as root or `sudo -i` first. Don't run any system updates before running Barracuda installer. You should use vanilla system. # cd # wget -q -U icab # bash BOA.sh.txt You are prepared now. But before starting installation, you have to configure it first. 26

27 BARRACUDA IMPORTANT! Don't run any installer via sudo. You must be logged in as root or `sudo -i` first. Don't run any system updates before running Barracuda installer. You should use vanilla system. # cd # wget -q -U icab # bash BOA.sh.txt # { make changes in.barracuda.cnf and.octopus.cnf } # boa in-stable public server.mydomain.org my@ o1 # boa in-stable public server2.mydomain2.org my2@ o2 mini 27
