Lamulo la funso la mtundu wa CentOS:

1. Onani mtundu wa Linux Kernel
uname -r

2. Onani mtundu wa CentOS
cat /etc/redhat-release

3. Onani mtundu wa PHP

4. Onani MySQL mtundu

5. Onani mtundu wa Apache
rpm -qa httpd

6. Onani zambiri za CPU

【pulogalamu】

rpm -qa
# onani zonse zomwe zayikidwa软件Phukusi

# Yambitsaninso lamulo la ntchito wamba
service memcached restart

service monit restart
service mysqld restart
service mysql restart
service httpd restart

monit start all

service nginx restart

# kuyambitsanso CWP
service cwpsrv restart

# kuyambitsanso memcached
service memcached restart
service memcached start
service memcached stop

# boot kuyamba memcached
chkconfig memcached on

Yambitsaninso httpd kuti code igwire ntchito:
service httpd restart
service httpd start
service httpd stop

chkconfig httpd on

tsegulaninso lamulo la httpd:
service httpd force-reload
service httpd reload

Lamulo loyambitsanso la Nginx:
/etc/init.d/nginxd restart

service nginxd force-reload
service nginxd reload
service nginxd restart

php-fpm kuyambitsanso lamulo:
/etc/init.d/php-fpm restart
service php-fpm restart
service php-fpm start

Ikaninso php-fpm:
sudo yum reinstall php-fpm

service mysql restart
service mysqld restart

service mysql stop
service mysqld stop

service mysql start
service mysqld start

Gwiritsani ntchito lamulo ili kuti muwone kagwiritsidwe ntchito ka kukumbukira ndikusintha masanjidwe ogwiritsira ntchito kukumbukira:
free -m
ps -eo pmem,pcpu,rss,vsize,args | sort -k 1 -r | less

MySQL_upgrade amatsatira malamulo otsatirawa kuti ayang'ane ndikukonza matebulo ndikukweza matebulo adongosolo:
mysqlcheck --all-databases --check-upgrade --auto-repair

Tsekani lamulo la MySQL:
killall mysqld

Onani ndondomeko ya mysql:
ps -ef|grep mysqld
watch -n 1 "ps -ef | grep mysql"

pid-file=/var/lib/mysql/centos-cwl.pid

Njira ya fayilo ya PID ya MYSQL, KLOXO-MR imatha kuwonedwa kudzera pagawo lowongolera "njira":
pid-file=/var/lib/mysql/centos-512mb-sfo1-01.pid
pid-file=/var/lib/mysql/xxxx.pid

kapena SSH lamula "ps -ef" kuti muwone njira zonse:
check process apache with pidfile /usr/local/apache/logs/httpd.pid
check process mysql with pidfile /var/run/mysqld/mysqld.pid

Mutha kuwonjezera mzerewu ku /etc/crontab kuti muyambe lamulo mphindi iliyonse kuti muwone momwe mysql ilili:
* * * * * /sbin/service mysql status || service mysql start

【Mot Command】

monit standard start, siyani, yambitsaninso malamulo:
/etc/init.d/monit start
/etc/init.d/monit stop
/etc/init.d/monit restart

yang'ananiChidziwitso:
Popeza monit imayikidwa ngati njira ya daemon, ndipo zosintha zomwe zimayamba ndi dongosolo zimawonjezedwa ku inittab, ngati njira ya monit itayima, init idzayambiranso, ndikuyang'anira ntchito zina, zomwe zikutanthauza kuti ntchito zoyang'aniridwa ndi monit sizingatheke. anasiya kugwiritsa ntchito njira wamba, chifukwa kamodzi anasiya, monit adzawayambitsanso.

Kuti muyimitse ntchito yoyang'aniridwa ndi monit, lamulo ngati monit stop name liyenera kugwiritsidwa ntchito, mwachitsanzo kuyimitsa tomcat:
monit stop tomcat

Kuyimitsa ntchito zonse zomwe zimayang'aniridwa ndi kugwiritsa ntchito monit:
monit stop all

Kuti muyambe ntchito mutha kugwiritsa ntchito lamulo monit stop name,

Kuyamba zonse ndi:
monit start all

Khazikitsani monit kuti muyambe ndi dongosolo ndikuwonjezera kumapeto kwa fayilo /etc/inittab
# Thamangani monit mumayendedwe okhazikika
mo:2345:respawn:/usr/local/bin/monit -Ic /etc/monitrc

Chotsani monit:
yum remove monit

【Koperani ndi decompress】

下载 WordPress 最新 版本
wget http://zh.wordpress.org/latest-zh_CN.tar.gz

unzip
tar zxvf latest-zh_CN.tar.gz

Sunthani mafayilo omwe ali mufoda ya wordpress (njira yamtheradi) kupita kumalo omwe alipo
mv wordpress/* .

Sunthani / cgi-bin chikwatu ku chikwatu chapano
$mv wwwroot/cgi-bin .

Koperani mafayilo onse omwe ali m'ndandanda wamakono ku bukhu lapitalo

Momwe mungayimitse / kuyambitsanso / kuyambitsanso ntchito ya redis?
Ngati mudayika redis ndi apt-get kapena yum install, mutha kuyimitsa / kuyambitsa / kuyambitsanso redis mwachindunji ndi malamulo awa.
/etc/init.d/redis-server stop
/etc/init.d/redis-server start
/etc/init.d/redis-server restart
/etc/init.d/redis restart

Ngati mwayika redis kuchokera ku code source, mutha kuyambitsanso redis kudzera mu lamulo lotseka la redis-cli, pulogalamu ya kasitomala ya redis:
redis-cli -h 127.0.0.1 -p 6379 shutdown

Ngati palibe njira zomwe zili pamwambazi zomwe zapambana kuyimitsa redis, mutha kugwiritsa ntchito chida chachikulu:
kill -9

[Onani lamulo lamalo a fayilo]

Onani komwe fayilo yosinthira PHP imayikidwa:
Gwiritsani ntchito phpinfo kuti muwone kuti ngati ntchitoyo ndi yoletsedwa, perekani pansi pa chipolopolo
php -v / -name php.ini
或者
find / -name php.ini

Nthawi zambiri, linux ikayikidwa pang'ono, wget sidzakhazikitsidwa mwachisawawa.
yum kukhazikitsa
yum -y install wget

Kusintha kwadongosolo kukuchitika ndipo yum yatsekedwa.
Mutha kukakamiza njira ya yum kutseka:
rm -f /var/run/yum.pid

Kuyang'ana perl...Perl sanapezeke pa makina anu: Chonde ikani perl ndikuyesa again
Mwachiwonekere, perl iyenera kukhazikitsidwa.
yum -y install perl perl*

[Malamulo a SSH a gulu lowongolera la Kloxo-MR]

Zalephera kukhazikitsa mitu kapena mapulagini okhala ndi "Simungathe kupanga chikwatu"
Yankho: sinthaninso zilolezo za pulogalamu yowonjezera ya wp ndikukweza foda
Pachitetezo cha seva, zilolezo za 777 sizingaperekedwe zonse, bola ngati maulalo awa akupatsidwa zilolezo za 755, eni ake okha ali ndi chilolezo cholemba.

Ngati mutayendetsa lamulo ili:
sh /script/fix-chownchmod

Kloxo-MR idzayesa kukonzanso umwini ndi zilolezo pamafayilo ndi zolemba pamasamba atsambali

Kloxo-MR Control Panel: Pitani ku "admin> Server> (localhost)> IP Address> Reread IP".

Kusintha kwa seva
Sinthani seva kukhala mtundu waposachedwa
yum -y update

Njira yomwe ili pamwambayi yayesedwa nthawi zambiri, koma pakadali vuto, chonde lowetsani lamulo lokonzekera:
yum clean all; yum update -y; sh /script/cleanup

(Muzosintha za pulogalamuyo, pitani mukadye pakapita nthawi ndikubwerera kuti mudzawone, tsitsimutsaniufo.org.in, izi.ufoMasamba a .org.in abwerera mwakale)

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

Kuonetsetsa kuti ma dns akuphatikizidwa "ziwerengero", mutatha kukonzanso yum kuyeretsa zonse; yum update -y; sh /script/cleanup, onetsetsani kuti mukuthamanga:
sh /script/fixdnsaddstatsrecord

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

Ikaninso Kloxo-MR:
Ngati palibe zolakwika zomwe zapezeka, yesani lamulo ili:
