## 【CentOS Service version lus nug]
CentOS kev pabcuam version lus nug hais kom ua:

1. Tshawb xyuas Linux Kernel version
uname -r

2. Txheeb xyuas CentOS version
cat /etc/redhat-release

3. Tshawb xyuas PHP version
php -v

4. Saib MySQL version
mysql -v

5. Txheeb xyuas Apache version
rpm -qa httpd

6. Saib cov ntaub ntawv CPU tam sim no
cat /proc/cpuinfo

7. Txheeb xyuas qhov zaus cpu tam sim no
cat /proc/cpuinfo | grep MHz

【Program】

rpm -qa
# saib tag nrho cov teeb tsaSoftwarePob

#Restart cov lus txib rau cov kev pab cuam
service memcached restart

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

monit start all

service nginx restart

#restart CWP
service cwpsrv restart

# rov pib memcached
service memcached restart
service memcached start
service memcached stop

#boot pib memcached
chkconfig memcached on

Rov pib httpd los ua kom cov cai siv cov lus txib:
service httpd restart
service httpd start
service httpd stop

chkconfig httpd on

reload httpd hais kom ua:
service httpd force-reload
service httpd reload

Nginx restart command:
/etc/init.d/nginxd restart

service nginxd force-reload
service nginxd reload
service nginxd restart

php-fpm restart hais kom ua:
/etc/init.d/php-fpm restart
service php-fpm restart
service php-fpm start

Reinstall 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

Siv cov lus txib hauv qab no kom pom kev siv lub cim xeeb thiab cov txheej txheem kev siv cim xeeb qeb:
free -m
ps -eo pmem,pcpu,rss,vsize,args | sort -k 1 -r | less

mysql_upgrade executes cov lus txib hauv qab no los xyuas thiab kho cov ntxhuav thiab txhim kho cov kab ke:
mysqlcheck --all-databases --check-upgrade --auto-repair

Kaw MySQL hais kom ua:
killall mysqld

Saib cov txheej txheem mysql:
ps -ef|grep mysqld
watch -n 1 "ps -ef | grep mysql"

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

Txoj kev PID cov ntaub ntawv ntawm MYSQL, KLOXO-MR tuaj yeem pom los ntawm kev tswj vaj huam sib luag "txheej txheem":
pid-file=/var/lib/mysql/centos-512mb-sfo1-01.pid
pid-file=/var/lib/mysql/xxxx.pid

los yog SSH hais kom ua "ps -ef" kom pom tag nrho cov txheej txheem:
check process apache with pidfile /usr/local/apache/logs/httpd.pid
check process mysql with pidfile /var/run/mysqld/mysqld.pid

Koj tuaj yeem ntxiv cov kab no rau /etc/crontab los pib cov lus txib txhua feeb los xyuas mysql xwm txheej:
* * * * * /sbin/service mysql status || service mysql start

【Monit hais kom ua】

monit standard start, stop, restart commands:
/etc/init.d/monit start
/etc/init.d/monit stop
/etc/init.d/monit restart

tsom kwmNco tseg:
Txij li thaum monit tau teeb tsa ua tus txheej txheem daemon, thiab cov chaw pib nrog lub kaw lus tau ntxiv rau inittab, yog tias cov txheej txheem monit nres, cov txheej txheem init yuav rov pib dua nws, thiab saib xyuas lwm cov kev pabcuam, uas txhais tau hais tias monit monitors Services tsis tuaj yeem ua tau. nres siv txoj kev li ib txwm, vim tias ib zaug nres, monit yuav pib lawv dua.

Txhawm rau nres qhov kev pabcuam saib xyuas los ntawm monit, cov lus txib zoo li monit nres lub npe yuav tsum tau siv, piv txwv li kom nres tomcat:
monit stop tomcat

Txhawm rau txwv txhua qhov kev pabcuam saib xyuas los ntawm kev siv monit:
monit stop all

Txhawm rau pib qhov kev pabcuam koj tuaj yeem siv cov lus txib monit nres lub npe,

Yuav pib txhua yam yog:
monit start all

Teem monit pib nrog lub kaw lus thiab ntxiv rau qhov kawg ntawm cov ntaub ntawv /etc/inittab
# Khiav monit hauv tus qauv khiav-qib
mo:2345:respawn:/usr/local/bin/monit -Ic /etc/monitrc

Uninstall monit:
yum remove monit

【Download thiab decompress】

Saib wordpress Qhov tseeb version ntawm
wget http://zh.wordpress.org/latest-zh_CN.tar.gz

unzip
tar zxvf latest-zh_CN.tar.gz

Txav cov ntaub ntawv hauv wordpress folder (txoj kev meej) mus rau qhov chaw teev npe tam sim no
mv wordpress/* .

Txav mus rau /cgi-bin directory rau cov npe tam sim no
$mv wwwroot/cgi-bin .

Luam tag nrho cov ntaub ntawv hauv daim ntawv teev npe tam sim no mus rau cov ntawv teev dhau los
cp -rpf -f * ../

Yuav ua li cas nres / restart / pib redis kev pab cuam?
Yog tias koj tau nruab redis nrog apt-get lossis yum nruab, koj tuaj yeem nres / pib / rov pib dua tshiab ncaj qha nrog cov lus txib hauv qab no
/etc/init.d/redis-server stop
/etc/init.d/redis-server start
/etc/init.d/redis-server restart
/etc/init.d/redis restart

Yog tias koj tau teeb tsa redis los ntawm qhov chaws, koj tuaj yeem rov pib dua redis los ntawm kev kaw lus ntawm redis-cli, tus neeg siv khoom ntawm redis:
redis-cli -h 127.0.0.1 -p 6379 shutdown

Yog tias tsis muaj txoj hauv kev saum toj no ua tiav hauv kev txwv redis, koj tuaj yeem siv riam phom kawg:
kill -9

[Saib cov ntaub ntawv qhov chaw hais kom ua]

Saib qhov twg PHP configuration file muab tso rau:
Siv phpinfo kom pom tias yog qhov ua haujlwm raug txwv, ua rau hauv qab lub plhaub
php -v / -name php.ini

find / -name php.ini

Feem ntau, thaum linux tau nruab tsawg kawg nkaus, wget yuav tsis raug ntsia los ntawm lub neej ntawd.
yim install
yum -y install wget

System auto-upgrade yog khiav thiab yum raug kaw.
Koj tuaj yeem yuam cov txheej txheem yum kaw:
rm -f /var/run/yum.pid

Tshawb xyuas perl...Perl tsis pom ntawm koj lub cev: Thov nruab perl thiab sim again
Obviously, perl yuav tsum tau muab ntsia.

[SSH cov lus txib rau Kloxo-MR tswj vaj huam sib luag]

Thaum txhim kho lub ntsiab lus lossis plugin, nws ua tsis tiav nrog "Unable to create directory"
Kev daws: rov hloov cov kev tso cai ntawm wp ntsiab plugin thiab upload folder
Rau kev ruaj ntseg neeg rau zaub mov, peb tsis tuaj yeem muab tag nrho 777 kev tso cai, tsuav yog cov npe no tau muab 755 tso cai, tsuas yog tus tswv tau tso cai sau.

Yog tias koj khiav cov lus txib hauv qab no:
sh /script/fix-chownchmod

Kloxo-MR yuav sim kho cov tswv cuab thiab kev tso cai ntawm cov ntaub ntawv thiab cov npe hauv lub vev xaib cov ntaub ntawv hauv paus

Kloxo-MR Control Vaj Huam Sib Luag: Mus rau "admin> Server> (localhost)> IP chaw nyob> Rov nyeem IP".

Server hloov tshiab
Hloov kho lub server mus rau qhov tseeb version
yum -y update

Cov txheej txheem saum toj no tau sim ntau zaus, tab sis tseem muaj teeb meem, thov nkag mus rau cov lus qhia kho hauv qab no:
yum clean all; yum update -y; sh /script/cleanup

(Nyob rau hauv qhov kev pab cuam hloov tshiab, mus noj tom qab ib pliag thiab rov los xyuas, refreshufo.org.in, ib.ufo.org.in nplooj ntawv rov qab mus rau qhov qub)

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

Txhawm rau kom ntseeg tau tias cov ntaub ntawv dns suav nrog "kev txheeb cais", tom qab hloov kho yum huv tag nrho; yum hloov tshiab -y; sh /script / cleanup, nco ntsoov khiav:
sh /script/fixdnsaddstatsrecord

Txhim kho Kloxo-MR:
yum clean all; yum update kloxomr7 -y; yum update -y

Reinstall Kloxo-MR:
Yog tias tsis pom qhov yuam kev, sim cov lus txib hauv qab no:
sh /script/upcp -y
