Deux façons de configurer Linux pour démarrer automatiquement l'exécution des scripts au démarrage

Script qidong.sh à démarrer au démarrage

[root@c69-01 scripts]<span class="hljs-comment"># vim /server/scripts/qidong.sh</span>

[root@c69-01 scripts]<span class="hljs-comment"># cat /server/scripts/qidong.sh</span>
<span class="hljs-meta">#!/bin/bash</span>
/bin/<span class="hljs-built_in">echo</span> $(/bin/date +%F_%T) >> /tmp/qidong.log

Méthode 1 : Modifier /etc/rc.local

/etc/rc.local, ce fichier est un fichier lien

[root@c69<span class="hljs-number">-01</span> ~]# ll /etc/rc.<span class="hljs-keyword">local</span> 
lrwxrwxrwx. <span class="hljs-number">1</span> root root <span class="hljs-number">13</span> Feb  <span class="hljs-number">5</span> <span class="hljs-number">10</span>:<span class="hljs-number">03</span> /etc/rc.<span class="hljs-keyword">local</span> -> rc.d/rc.<span class="hljs-keyword">local</span>

Modifiez le fichier /etc/rc.local

[root<span class="hljs-variable">@c69</span>-<span class="hljs-number">01</span> scripts]<span class="hljs-comment"># tail -n 1 /etc/rc.local </span>
/bin/bash /server/scripts/qidong.sh ><span class="hljs-regexp">/dev/null</span> <span class="hljs-number">2</span>><span class="hljs-regexp">/dev/null</span>

Redémarrez le système et vérifiez les résultats

<span class="hljs-selector-attr">[root@c69-01 ~]</span># <span class="hljs-selector-tag">cat</span> /<span class="hljs-selector-tag">tmp</span>/<span class="hljs-selector-tag">qidong</span><span class="hljs-selector-class">.log</span> 
<span class="hljs-selector-tag">2018-02-19_23</span><span class="hljs-selector-pseudo">:30</span><span class="hljs-selector-pseudo">:56</span>

Ce script a été démarré automatiquement après le démarrage

Méthode 2 : gestion chkconfig

Supprimer la configuration de la méthode 1

[root@c69-01 ~]<span class="hljs-comment"># vim /etc/init.d/test </span>
<span class="hljs-meta">#!/bin/bash</span>
<span class="hljs-comment"># chkconfig: 3 88 88</span>
/bin/bash /server/scripts/qidong.sh >/dev/null 2>/dev/null

[root@c69-01 ~]<span class="hljs-comment"># chmod +x /etc/init.d/test</span>

Ajouter à chkconfig et démarrer automatiquement au démarrage

[root<span class="hljs-variable">@c69</span>-<span class="hljs-number">01</span> ~]<span class="hljs-comment"># chkconfig --add test</span>

[root<span class="hljs-variable">@c69</span>-<span class="hljs-number">01</span> ~]<span class="hljs-comment"># chkconfig --list test</span>
test           	<span class="hljs-number">0</span><span class="hljs-symbol">:off</span>	<span class="hljs-number">1</span><span class="hljs-symbol">:off</span>	<span class="hljs-number">2</span><span class="hljs-symbol">:off</span>	<span class="hljs-number">3</span><span class="hljs-symbol">:on</span>	<span class="hljs-number">4</span><span class="hljs-symbol">:off</span>	<span class="hljs-number">5</span><span class="hljs-symbol">:off</span>	<span class="hljs-number">6</span><span class="hljs-symbol">:off</span>

Redémarrez le système et vérifiez les résultats

<span class="hljs-selector-attr">[root@c69-01 ~]</span># <span class="hljs-selector-tag">cat</span> /<span class="hljs-selector-tag">tmp</span>/<span class="hljs-selector-tag">qidong</span><span class="hljs-selector-class">.log</span> 
<span class="hljs-selector-tag">2018-02-19_23</span><span class="hljs-selector-pseudo">:30</span><span class="hljs-selector-pseudo">:56</span>
2018-02-19_23:59:10

Opération réussie

Éteignez et démarrez

[root<span class="hljs-variable">@c69</span>-<span class="hljs-number">01</span> ~]<span class="hljs-comment"># chkconfig test off</span>
[root<span class="hljs-variable">@c69</span>-<span class="hljs-number">01</span> ~]<span class="hljs-comment"># chkconfig --list test</span>
test           	<span class="hljs-number">0</span><span class="hljs-symbol">:off</span>	<span class="hljs-number">1</span><span class="hljs-symbol">:off</span>	<span class="hljs-number">2</span><span class="hljs-symbol">:off</span>	<span class="hljs-number">3</span><span class="hljs-symbol">:off</span>	<span class="hljs-number">4</span><span class="hljs-symbol">:off</span>	<span class="hljs-number">5</span><span class="hljs-symbol">:off</span>	<span class="hljs-number">6</span><span class="hljs-symbol">:off</span>

Supprimer le test de la gestion chkconfig

[root<span class="hljs-variable">@c69</span>-<span class="hljs-number">01</span> ~]<span class="hljs-comment"># chkconfig --list test</span>
test           	<span class="hljs-number">0</span><span class="hljs-symbol">:off</span>	<span class="hljs-number">1</span><span class="hljs-symbol">:off</span>	<span class="hljs-number">2</span><span class="hljs-symbol">:off</span>	<span class="hljs-number">3</span><span class="hljs-symbol">:off</span>	<span class="hljs-number">4</span><span class="hljs-symbol">:off</span>	<span class="hljs-number">5</span><span class="hljs-symbol">:off</span>	<span class="hljs-number">6</span><span class="hljs-symbol">:off</span>

[root<span class="hljs-variable">@c69</span>-<span class="hljs-number">01</span> ~]<span class="hljs-comment"># chkconfig --del test</span>

[root<span class="hljs-variable">@c69</span>-<span class="hljs-number">01</span> ~]<span class="hljs-comment"># chkconfig --list test</span>
service test supports chkconfig, but is <span class="hljs-keyword">not</span> referenced <span class="hljs-keyword">in</span> any runlevel (run <span class="hljs-string">'chkconfig --add test'</span>)

Les deux méthodes ci-dessus de scripts à démarrage automatique au démarrage sont uniquement à titre de référence. Les lecteurs peuvent les configurer en fonction de leurs propres circonstances !

Remarque : le système que j'utilise est la version CentOS 6.9 (finale)
