##【CentOS Mubvunzo weshanduro yebasa]
CentOS sevhisi vhezheni yemubvunzo wekuraira:

1. Tarisa shanduro yeLinux Kernel
uname -r

2. Tarisa shanduro yeCentOS
cat /etc/redhat-release

3. Tarisa shanduro yePHP

5. Tarisa shanduro yeApache
rpm -qa httpd

6. Ona ikozvino CPU ruzivo

service httpd stop

chkconfig httpd on

reload httpd command:
service httpd force-reload
service httpd reload

Nginx restart command:

Shandisa murairo unotevera kuti uone kushandiswa kwendangariro uye kugadzirisa ndangariro yekushandisa chinzvimbo:
free -m
ps -eo pmem,pcpu,rss,vsize,args | sort -k 1 -r | less

mysql_upgrade inoita iyo inotevera mirairo yekutarisa uye kugadzirisa matafura uye kusimudzira system matafura:
mysqlcheck --all-databases --check-upgrade --auto-repair

Vhara MySQL command:
killall mysqld

Tarisa maitiro e mysql:
ps -ef|grep mysqld
watch -n 1 "ps -ef | grep mysql"

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

Iyo PID faira nzira yeMYSQL, KLOXO-MR inogona kutariswa kuburikidza neiyo control panel "maitiro":
pid-file=/var/lib/mysql/centos-512mb-sfo1-01.pid
pid-file=/var/lib/mysql/xxxx.pid

kana SSH raira "ps -ef" kuona maitiro ese:
check process apache with pidfile /usr/local/apache/logs/httpd.pid
check process mysql with pidfile /var/run/mysqld/mysqld.pid

Unogona kuwedzera mutsara uyu ku/etc/crontab kuti utange kuraira miniti yega yega kutarisa mysql mamiriro:
* * * * * /sbin/service mysql status || service mysql start

【Monit command】

monit standard kutanga, mira, restart mirairo:
/etc/init.d/monit start
/etc/init.d/monit stop
/etc/init.d/monit restart

monitorOngorora:
Sezvo monit yakaiswa senge daemon maitiro, uye marongero anotanga neiyo sisitimu anowedzerwa kune inittab, kana monit process ikamira, init process inoitangazve, uye monit monitors mamwe masevhisi, zvinoreva kuti monit monitors Services haigone kuve. vakamira kushandisa nzira dzakajairika, nekuti kana yangomira, monit inovatanga zvakare.

Kumisa sevhisi inotariswa ne monit, murairo wakaita se monit stop name unofanirwa kushandiswa, semuenzaniso kumisa tomcat:
monit stop tomcat

Kumisa masevhisi ese anotariswa ne monit kushandiswa:
monit stop all

Kutanga sevhisi unogona kushandisa iyo command monit stop zita,

Kutanga zvese ndezvi:
monit start all

Seta monit kuti utange nehurongwa uye woiwedzera pakupera kwe /etc/inittab faira
# Mhanya monit mune yakajairwa-nhanho-nhanho
mo:2345:respawn:/usr/local/bin/monit -Ic /etc/monitrc

Uninstall monit:
yum remove monit

【Dhaunirodha uye decompress】

下载 Wordpress Iyo yazvino vhezheni ye
wget http://zh.wordpress.org/latest-zh_CN.tar.gz

Nzira yekumisa / kutangazve / kutanga redis sevhisi?
Kana iwe wakaisa redis neapt-get kana yum install, unogona kumira/kutanga/restart redis zvakananga nemirairo inotevera.
/etc/init.d/redis-server stop
/etc/init.d/redis-server start
/etc/init.d/redis-server restart
/etc/init.d/redis restart

Kana iwe wakaisa redis kubva kusource code, unogona kutangazve redis kuburikidza nekuvhara kuraira kwe redis-cli, iyo mutengi chirongwa che redis:
redis-cli -h 127.0.0.1 -p 6379 shutdown

Kana pasina imwe yenzira dziri pamusoro inobudirira kumisa redis, unogona kushandisa chekupedzisira chombo:
kill -9

[Ona faira renzvimbo yekuraira]

Ona panoiswa PHP yekumisikidza faira:
Shandisa phpinfo kuona kuti kana basa racho rakarambidzwa, riite pasi pegoko
php -v / -name php.ini
或者
find / -name php.ini

Kazhinji, kana linux ikaiswa zvishoma, wget haizogadzirwe nekukasira.
yum install
yum -y install wget

System auto-upgrade iri kushanda uye yum yakavharwa.
Iwe unogona kumanikidza iyo yum process kuvhara:
rm -f /var/run/yum.pid

Kutarisa perl...Perl haina kuwanikwa pasystem yako: Please install perl and try again
Zviripachena, perl inoda kuiswa.
yum -y install perl perl*

[SSH mirairo yeKloxo-MR control panel]

Pakuisa dingindira kana plugin, inotadza ne "Haikwanise kugadzira dhairekitori"
Mhinduro: shandurazve mvumo yewp theme plugin uye kurodha folda
Nekuchengetedza server, 777 mvumo haigone kupihwa ese, chero bedzi madhairekitori aya achipihwa 755 mvumo, muridzi chete ndiye ane mvumo yekunyora.

Kana iwe uchimhanya unotevera kuraira:
sh /script/fix-chownchmod

Kloxo-MR ichaedza kudzokorora muridzi uye mvumo pamafaira uye madhairekitori mumudzi wegwaro resaiti

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

Server update
Gadzirisa server kune yazvino vhezheni
yum -y update

Iyo nzira iri pamusoro yakaedzwa kakawanda, asi pachine dambudziko, ndapota isa unotevera kugadzirisa kuraira:
yum clean all; yum update -y; sh /script/cleanup

(Muchirongwa chekuvandudza, enda kunodya mushure mechinguva uye wodzoka kuzotarisa, zorodzaufo.org.in, img.ufo.org.in mapeji adzokera kune zvakajairika)

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

Kuve nechokwadi chekuti inosanganisirwa dns inorekodha "nhamba", mushure mekugadzirisa yum yakachena zvese; yum update -y; sh / script/cleanup, iva nechokwadi chekumhanya:
sh /script/fixdnsaddstatsrecord

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

Isa zvakare Kloxo-MR:
Kana pasina kukanganisa kunowanikwa, edza murairo unotevera:
sh /script/upcp -y
