No ka mea, ua hoʻonoho ʻia ka monit ma ke ʻano he daemon, a ua hoʻohui ʻia nā hoʻonohonoho e hoʻomaka me ka ʻōnaehana i inittab, inā pau ke kaʻina monit, e hoʻomaka hou ke kaʻina hana, a nānā ʻo monit i nā lawelawe ʻē aʻe, ʻo ia hoʻi, ʻaʻole hiki i ka monit monitor ke lawelawe. e ho'ōki i ka hoʻohana ʻana i ke ʻano maʻamau, no ka mea, i ka wā i kū ai, e hoʻomaka hou ka monit.

No ka ho'ōkiʻana i kahi lawelawe i nānāʻia e ka monit, pono e hoʻohanaʻia kahi kauoha e like me ka monit stop name, no ka laʻana e ho'ōki i ka tomcat:
monit stop tomcat

No ka hooki ʻana i nā lawelawe āpau i nānā ʻia e ka hoʻohana monit:
monit stop all

No ka hoʻomaka ʻana i kahi lawelawe hiki iā ʻoe ke hoʻohana i ke kauoha monit stop name,

E hoʻomaka i nā mea a pau:

E hoʻonohonoho i ka monit e hoʻomaka me ka ʻōnaehana a hoʻohui iā ia ma ka hopena o ka faila /etc/inittab
# Holo i ka monit ma nā pae holo maʻamau

【Hoʻoiho a hoʻopau i ka hoʻoemi】

Hoʻoiho wordpress ʻO ka mana hou loa o

Pehea e hooki/hoʻomaka/hoʻomaka i ka lawelawe redis?
Inā hoʻokomo ʻoe i ka redis me ka apt-get a i ʻole yum install, hiki iā ʻoe ke hoʻōki/hoʻomaka/hoʻomaka hou i ka redis pololei me kēia mau kauoha.
/etc/init.d/redis-server stop
/etc/init.d/redis-server start
/etc/init.d/redis-server restart
/etc/init.d/redis restart

Inā hoʻokomo ʻoe i ka redis mai ka code source, hiki iā ʻoe ke hoʻomaka hou i ka redis ma o ke kauoha pani o ka redis client program redis-cli:
redis-cli -h 127.0.0.1 -p 6379 shutdown

Inā ʻaʻole kūleʻa kekahi o nā ala i luna i ka hoʻōki ʻana i ka redis, hiki iā ʻoe ke hoʻohana i ka mea kaua hope loa:
kill -9

[Nānā i ke kauoha wahi waihona]

E ʻike i kahi i waiho ʻia ai ka faila hoʻonohonoho PHP:
E hoʻohana i ka phpinfo e ʻike inā pāpā ʻia ka hana, e hoʻokō ma lalo o ka pūpū
php -v / -name php.ini
或者
find / -name php.ini

ʻO ka maʻamau, ke hoʻokomo liʻiliʻi ʻia ka linux, ʻaʻole e hoʻokomo ʻia ʻo wget ma ka paʻamau.
yum hoʻokomo
yum -y install wget

Ke holo nei ka hoʻonui ʻana i ka ʻōnaehana a paʻa ka yum.
Hiki iā ʻoe ke koi i ke kaʻina hana yum e pani:
rm -f /var/run/yum.pid

Ke nānā nei no ka perl...ʻaʻole i loaʻa ʻo Perl ma kāu ʻōnaehana: E ʻoluʻolu e hoʻokomo i ka perl a hoʻāʻo iā again
ʻIke ʻia, pono e hoʻokomo ʻia ka perl. Penei ke kauoha hoʻokomo perl:
yum -y install perl perl*

[Nā kauoha SSH no Kloxo-MR control panel]

Ke hoʻokomo ʻana i kahi kumumanaʻo a i ʻole plugin, hāʻule me "ʻAʻole hiki ke hana i ka papa kuhikuhi"
Pane: hoʻololi hou i nā ʻae o ka wp theme plugin a hoʻouka i ka waihona
No ka palekana o ke kikowaena, ʻaʻole hiki iā mākou ke hāʻawi i nā ʻae 777 a pau, no laila ke hāʻawi ʻia kēia mau papa kuhikuhi i nā ʻae 755, ʻo ka mea nona ka ʻae e kākau.

Inā holo ʻoe i kēia kauoha:
sh /script/fix-chownchmod

E hoʻāʻo ʻo Kloxo-MR i ka hoʻoponopono ʻana i ka mana a me nā ʻae i nā faila a me nā papa kuhikuhi ma ke kumu palapala o ka pūnaewele

Kloxo-MR Control Panel: E hele i "admin> Server> (localhost)> IP Address> Reread IP".

Hoʻohou kikowaena
Hoʻohou i ke kikowaena i ka mana hou loa
yum -y update

Ua ho'āʻo pinepine ʻia nā ʻano hana i luna, akā aia ka pilikia, e ʻoluʻolu e hoʻokomo i kēia kauoha hoʻoponopono:
yum clean all; yum update -y; sh /script/cleanup

(Ma ka polokalamu hou, hele e ʻai ma hope o kekahi manawa a hoʻi mai e nānā, hōʻoluʻoluufo.org.in, img.ufoUa hoʻi nā ʻaoʻao .org.in i ka mea maʻamau)

yum clean all; yum update -y; sh /script/cleanup
service httpd restart

No ka hōʻoia ʻana e hoʻopaʻa ʻia nā dns i nā "statistics", ma hope o ka hoʻonui ʻana i ka yum clean all; yum update -y; sh /script/cleanup, e holo pono:
sh /script/fixdnsaddstatsrecord

Hoʻonui Kloxo-MR:
yum clean all; yum update kloxomr7 -y; yum update -y

E hoʻouka hou iā Kloxo-MR:
Inā ʻaʻohe hewa, e hoʻāʻo i kēia kauoha:
