mySQL 5.5 auf Debian Squeeze installieren

mySQL Server 5.5 auf Debian Squeeze

Wer einen performanten mySQL Server 5.5 unter Debian Squeeze betreiben will – muss auf das normale Debian Packet verzichten und manuell installieren, da die “offizielle” Variante aus dem Repositry leider etwas stark veraltet ist.

Ist aber grundsätzlich kein Hexenwerk – so gehts:

Sofern bestehende Datenbanken vorhanden sind – Backup erstellen! Ich gehe davon aus dass es hierzu kein HowTo braucht

Alte Installation bereinigen, sofern vorhanden:

apt-get remove mysql-server mysql-common --purge &amp;&amp; apt-get autoremove

Danach sollte die “asynchronous I/O library”, kurz AIO aus dem Repository installiert werden – damit kann die spätere Performance von InnoDB massiv verbessert werden.

apt-get install libaio-dev

Analog zu Debian, sollte mySQL auch weiterhin unter einem eigenen Benutzer laufen, dazu legen wir diesen mit entsprechender Gruppe an, sofern notwendig.

useradd mysql
groupadd mysql

Danach werden die benötigten Ordner auf dem Filesystem angelegt und mit den nötigen Rechten versehen. In diesem Beispiel wird die Struktur analog zur normalen Packetinstallation aufgebaut. Diese sollte aber wenn möglich weiter optimiert werden. Ein paar Gedanken dazu sind in einem anderen Artikel zu finden.

mkdir /var/log/mysql &amp;&amp; chown -R mysql:mysql /var/log/mysql
mkdir -p /var/run/mysqld &amp;&amp; chown -R mysql:root /var/run/mysqld &amp;&amp; chmod -R 755 /var/run/mysqld
mkdir -p /var/lib/mysql &amp;&amp; chown -R mysql:mysql /var/lib/mysql &amp;&amp; chmod -R 700 /var/lib/mysql

Als nächstes brauchen wir nun das aktuellste “Linux Generic Tar Archive” von mySQL:
http://www.mysql.com/downloads/mysql/#downloads

Wählen sie unbedingt das korrekte Packet. Sollten sie unsicher sein bezüglich 32 oder 64 Bit – Fragen sie doch mal ihr System dazu

getconf LONG_BIT

In meinem Fall wurde die Version 5.5.15 (64 Bit) von Switch.ch heruntergeladen und entpackt:

cd /usr/local/src/ &amp;&amp; mkdir mysql5.5 &amp;&amp; cd mysql5.5
wget http://dev.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.15-linux2.6-x86_64.tar.gz/from/http://mirror.switch.ch/ftp/mirror/mysql/ -O mysql-5.5.15-linux2.6-x86_64.tar.gz
tar xzvf mysql-5.5.15-linux2.6-x86_64.tar.gz

In meinem Setup werden die Dateien anschliessen nach /usr/share/mysql verschoben und an den User mysql zugewiesen:

mv mysql-5.5.15-linux2.6-x86_64 /usr/local/mysql
chown mysql:mysql /usr/local/mysql/ -R

Als nächstes muss das mySQL-Bin Verzeichniss noch in den Path aufgenommen werden:

export PATH=/usr/local/mysql/bin:$PATH

Wenn alles klappt – sollte mySQL nun startklar sein. Ein kleiner Test schaded aber sicherlich nicht:

mysql -V &amp;&amp; mysqld -V

Sollte folgendes ans Licht bringen:

mysql  Ver 14.14 Distrib 5.5.15, for linux2.6 (x86_64) using readline 5.1
mysqld  Ver 5.5.15 for linux2.6 on x86_64 (MySQL Community Server (GPL))

Wenn alles geklappt hat, sollte noch die /etc/profile mit dem neuen Pfad ergänz werden damit diese Änderung permant wird. Auszug:

...
if [ "`id -u`" -eq 0 ]; then
  PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/mysql/bin"
else
  PATH="/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/usr/local/mysql/bin"
fi
export PATH
...

Nun brauchen wir noch die Konfiguration als /etc/mysql/my.cnf. Hierzu gibt es gute Templates welche übernommen werden können. In meinem Beispiel wurde die my-innodb-heavy-4G.cnf gewählt – es gäbe aber noch diverse Alternativen – am identischen Ort.

cp /usr/local/mysql/support-files/my-innodb-heavy-4G.cnf /etc/my.cnf

Folgende Anpassungen sind hier notwendig (anpassen/ergänzen):

[client]
socket          = /var/run/mysqld/mysqld.sock

[mysqld]
socket          = /var/run/mysqld/mysqld.sock
basedir         = /usr/local/mysql
datadir         = /var/lib/mysql/data
tmpdir          = /tmp
log_error       = /var/log/mysql/error.log

init.d Script erstellen:

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql &amp;&amp; chmod +x /etc/init.d/mysql

Hier sind nun noch 2 weitere Anpassungen notwendig:

basedir=/usr/local/mysql
datadir=/var/lib/mysql/data

Basisdatenbanken anlegen:

/usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql

Fertig – ein erster Startversuch:

/etc/init.d/mysql start

Sicherheits-Konfiguration setzten, dafür braucht es allerdings noch einen Symlink für den Socken:

ln -s /var/run/mysqld/mysqld.sock /tmp/mysql.sock
/usr/local/mysql/bin/mysql_secure_installation

Wird AIO auch wirklich angewendet? Ein Blick ins Log hilft weiter, folgender Eintrag muss erscheinen:

****** **:**:** InnoDB: Using Linux native AIO

Wenn alls OK ist – Server automatisch mit Bootprozess starten:

update-rc.d mysql defaults

Hallo habe lauter fehler sowie beim starten von mysql

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!

In order to log into MySQL to secure it, we’ll need the current
password for the root user. If you’ve just installed MySQL, and
you haven’t set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’ (2)

Test mal die Rechte auf deinem Datenordner (z.B. /usr/local/mysql/data). Ist dort etwas drin?

Hat das mysql_install_db fehlerfrei funktioniert?

Damit das mysql_secure_installation funktioniert, brauchst du den Symlink – wie in der Anleitung beschrieben. Aber erstmal musst den den Server zum fliegen bringen.

die rechte sind ok, ja da sind so einige dateien und ordner.
mysql_install_db hat ohne fehler funktioniert
wird die pid datei selber von mysql erstellt?
ich probier mal einen neustart dann probier ichs noch mal.
danke für die vorschläge

Thats it

Basisdatenbank anlegen ist falsch.
Es müsste so sein: /usr/local/mysql/scripts/mysql_install_db –user=mysql –ldata=/usr/local/mysql/data –basedir=/usr/local/mysql

ldata war falsch.

Vielen Dank fïr das Tutorial. Es muss jedoch /var/lib/mysql/data/ bei datadir sein.

[client]
socket = /var/run/mysqld/mysqld.sock

[mysqld]
socket = /var/run/mysqld/mysqld.sock
basedir = /usr/local/mysql
datadir = /var/lib/mysql/data/
tmpdir = /tmp
log_error = /var/log/mysql/error.log
