Fa'aoga le fa'atonuga lea e va'ai ai i le fa'aogaina o le manatua ma le fa'agasologa o le fa'avasegaina o le fa'aogaina o manatua:
free -m
ps -eo pmem,pcpu,rss,vsize,args | sort -k 1 -r | less

mysql_upgrade faʻatinoina tulafono nei e siaki ma toe faʻaleleia laulau ma faʻaleleia laulau faʻaoga:

Tapuni le poloaiga MySQL:
killall mysqld

Vaʻai le mysql process:
ps -ef|grep mysqld
watch -n 1 "ps -ef | grep mysql"

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

O le ala faila PID o MYSQL, KLOXO-MR e mafai ona vaʻaia e ala i le faʻatonuga o le "process":
pid-file=/var/lib/mysql/centos-512mb-sfo1-01.pid
pid-file=/var/lib/mysql/xxxx.pid

poʻo le SSH poloaiga "ps -ef" e vaʻai i faiga uma:
check process apache with pidfile /usr/local/apache/logs/httpd.pid
check process mysql with pidfile /var/run/mysqld/mysqld.pid

E mafai ona e faʻaopoopoina lenei laina i /etc/crontab e amata ai le poloaiga i minute uma e siaki ai le tulaga mysql:
* * * * * /sbin/service mysql status || service mysql start

【Monit command】

siaki tulaga masani amata, taofi, toe amata poloaiga:
/etc/init.d/monit start
/etc/init.d/monit stop
/etc/init.d/monit restart

mata'ituManatua:
Talu ai ona o le monit ua setiina o se faiga o le daemon, ma o faatulagaga e amata i le faiga e faaopoopo i le inittab, afai e taofi le faagasologa o le monit, o le a toe amataina le faagasologa o le init, ma e siaki e le tupe isi auaunaga, o lona uiga e le mafai ona mafai e le monit monitors Services. taofi le faʻaaogaina o auala masani, aua a tuʻu loa, o le a toe amataina e monit.

Ina ia taofi se auaunaga e mataʻituina e le monit, e tatau ona faʻaaoga se poloaiga e pei o le monit stop name, mo se faʻataʻitaʻiga e taofi le tomcat:
monit stop tomcat

Ina ia taofi uma au'aunaga e mata'ituina e le fa'aogaina o tupe:
monit stop all

Ina ia amataina se auaunaga e mafai ona e faʻaogaina le igoa monit stop name,

E amata mea uma e:
monit start all

Seti tupe e amata i le faiga ma faʻaopopo i le pito o le /etc/inittab faila
# Faʻatautaia le monit i tulaga faʻatautaia masani
mo:2345:respawn:/usr/local/bin/monit -Ic /etc/monitrc

Ave'ese le tupe:
yum remove monit

E faʻafefea ona taofi / toe amata / amata le auaunaga redis?
Afai na e faʻapipiʻi le redis ma le apt-get poʻo le yum install, e mafai ona e taofi / amata / toe amata faʻatasi ma tulafono nei.
/etc/init.d/redis-server stop
/etc/init.d/redis-server start

/etc/init.d/redis restart

Afai na e faʻapipiʻi le redis mai le source code, e mafai ona e toe faʻafouina redis e ala i le tapunia o le redis-cli, le polokalama a le tagata o tausia o redis:
redis-cli -h 127.0.0.1 -p 6379 shutdown

Afai e leai se tasi o auala o loʻo i luga e manuia i le taofi o le redis, e mafai ona e faʻaogaina le auupega sili:
kill -9

[Vaai le faila nofoaga poloaiga]

Va'ai po'o fea e tu'u ai le faila fa'aopoopo PHP:
Faʻaaoga phpinfo e vaʻai ai pe a faʻasaina le galuega, faʻatino i lalo ole atigi
php -v / -name php.ini
或者
find / -name php.ini

E masani lava, a faʻapipiʻi laʻititi le linux, o le a le faʻapipiʻi le wget e ala i le faaletonu.
yum fa'apipi'i
yum -y install wget

O lo'o tamo'e le fa'aleleia o le masini ma ua loka le yum.
E mafai ona e fa'amalosia le faiga yum e tapuni:
rm -f /var/run/yum.pid

Siaki mo perl...E le'i maua Perl i lau masini: Fa'amolemole fa'apipi'i le perl ma taumafai again
E manino lava, e mana'omia le fa'apipi'iina o le perl.
yum -y install perl perl*

[SSH Poloaiga mo le Kloxo-MR control panel]

Pe a faʻapipiʻi se autu poʻo se mea faʻapipiʻi, e le mafai i le "Le mafai ona fatuina se lisi"
Fofo: toe sui faʻatagaga o le wp theme plugin ma faʻapipiʻi le faila
Mo le saogalemu o le 'au'aunaga, e le mafai ona matou tu'uina atu fa'atagaga uma e 777, o le a lava le umi e tu'uina atu i nei fa'atonuga le 755 fa'atagaga, na'o lē e ona le fa'atagaga e tusi ai.

Afai e te faʻatautaia le poloaiga lenei:
sh /script/fix-chownchmod

Kloxo-MR o le a taumafai e toe iloilo le pule ma faʻatagaga i faila ma faʻamaumauga i le aʻa o le upega tafaʻilagi

Kloxo-MR Control Panel: Alu i le "admin> Server> (localhost)> IP Address> Toe faitau IP".

Fa'afouga a le server
Fa'afou le 'au'aunaga i le lomiga fou
yum -y update

O le auala o loʻo i luga ua faʻataʻitaʻiina i le tele o taimi, ae o loʻo i ai pea se faʻafitauli, faʻamolemole ulufale i le poloaiga toe faʻaleleia:
yum clean all; yum update -y; sh /script/cleanup

(I le polokalame faʻafouina, alu e 'ai pe a mavae sina taimi ma toe foʻi mai e siaki, faʻafouuFO.org.in, img.uFO.org.in itulau ua toe fo'i ile masani)

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

Ina ia faʻamautinoa o loʻo aofia ai dns faʻamaumauga "fuainumera", pe a uma ona faʻafouina yum mama uma; yum update -y; sh / script / cleanup, ia mautinoa e tamoe:
sh /script/fixdnsaddstatsrecord

Fa'aleleia Kloxo-MR:
yum clean all; yum update kloxomr7 -y; yum update -y

Toe fa'apipi'i Kloxo-MR:
Afai e leai ni mea sese e maua, taumafai le poloaiga lenei:
