##【CentOS Uiui putanga ratonga]
Putanga ratonga CentOS tono patai:

1. Tirohia te putanga Linux Kernel
uname -r

2. Tirohia te putanga CentOS
cat /etc/redhat-release

3. Tirohia te putanga PHP
php -v

4. Tirohanga MySQL putanga
mysql -v

5. Tirohia te putanga Apache
rpm -qa httpd

6. Tirohia nga korero PTM o naianei
cat /proc/cpuinfo

7. Tirohia te auau CPU o naianei
cat /proc/cpuinfo | grep MHz

【hōtaka】

rpm -qa
# tirohia nga mea katoa kua whakauruhia软件Paepae

#Tikia ano te whakahau mo nga ratonga noa
service memcached restart

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

monit start all

service nginx restart

#whakahou CWP
service cwpsrv restart

# whakaara ano i te memcached
service memcached restart
service memcached start
service memcached stop

#boot timata memcached
chkconfig memcached on

Tīmatahia te httpd kia whai mana te waehere:
service httpd restart
service httpd start
service httpd stop

chkconfig httpd on

utaina ano te whakahau httpd:
service httpd force-reload
service httpd reload

whakahau whakaara ano Nginx:
/etc/init.d/nginxd restart

service nginxd force-reload
service nginxd reload
service nginxd restart

php-fpm whakahau whakaara ano:
/etc/init.d/php-fpm restart
service php-fpm restart
service php-fpm start

Tāuta anōtia te 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

Whakamahia te whakahau e whai ake nei ki te kite i te whakamahinga mahara me te tukatuka i te raupapatanga whakamahi mahara:
free -m
ps -eo pmem,pcpu,rss,vsize,args | sort -k 1 -r | less

mysqlKa mahia e _upgrade nga whakahau e whai ake nei hei tirotiro me te whakatika i nga ripanga me te whakahou i nga ripanga punaha:
mysqlcheck --all-databases --check-upgrade --auto-repair

Katia te whakahau MySQL:
killall mysqld

Tirohia te tukanga mysql:
ps -ef|grep mysqld
watch -n 1 "ps -ef | grep mysql"

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

Ko te ara konae PID o MYSQL, KLOXO-MR ka taea te tiro ma te paewhiri mana "tukatuka":
pid-file=/var/lib/mysql/centos-512mb-sfo1-01.pid
pid-file=/var/lib/mysql/xxxx.pid

ranei SSH whakahau "ps -ef" ki te kite i nga tukanga katoa:
check process apache with pidfile /usr/local/apache/logs/httpd.pid
check process mysql with pidfile /var/run/mysqld/mysqld.pid

Ka taea e koe te taapiri i tenei raina ki /etc/crontab ki te tiimata i te whakahau ia meneti ki te tirotiro i te mana o mysql:
* * * * * /sbin/service mysql status || service mysql start

【Te tono monit】

aroturukihia te tiimata, ka mutu, ka timata ano nga whakahau:
/etc/init.d/monit start
/etc/init.d/monit stop
/etc/init.d/monit restart

TuhingaTuhipoka:
I te mea kua whakaritea te monit hei tukanga daemon, ka honoa nga tautuhinga ka tiimata me te punaha ki te inittab, mena ka mutu te mahi monit, ka timata ano te tukanga init, ka tirotirohia e te monit etahi atu ratonga, ko te tikanga ka aroturuki te monit Kaore e taea e te ratonga. kia mutu te whakamahi i te tikanga noa, na te mea ka mutu, ka timata ano te monit.

Hei aukati i tetahi ratonga e aro turukihia ana e monit, me whakamahi he whakahau penei i te ingoa mutu monit, hei tauira ki te aukati tomcat:
monit stop tomcat

Hei whakamutu i nga ratonga katoa e aroturukihia ana e te whakamahi monit:
monit stop all

Hei timata i tetahi ratonga, whakamahia te ingoa mooni mutu whakahau,

Hei timata katoa ko:
monit start all

Tautuhia te monit hei tiimata me te punaha ka taapiri atu ki te mutunga o te konae /etc/inittab
# Whakahaerehia te monit i roto i nga taumata oma paerewa
mo:2345:respawn:/usr/local/bin/monit -Ic /etc/monitrc

Wetetāuta moni:
yum remove monit

【Tikiake ka wetewetehia】

下载 wordPress Ko te putanga hou o
wget http://zh.wordpress.org/latest-zh_CN.tar.gz

wetewete
tar zxvf latest-zh_CN.tar.gz

Nukuhia nga konae kei te kōpaki wordpress (ara tino) ki te waahi whaiaronga o naianei
mv wordpress/* .

Nukuhia te whaiaronga /cgi-bin ki te whaiaronga onāianei
$mv wwwroot/cgi-bin .

Tārua ngā kōnae katoa i te whaiaronga o nāianei ki te whaiaronga o mua
cp -rpf -f * ../

Me pehea te whakamutu/whakahoutanga/tīmata i te ratonga redis?
Mena kua whakauruhia e koe te redis me te apt-get or yum install, ka taea e koe te whakamutu/tīmata/whakahou i te redis tika me nga whakahau e whai ake nei
/etc/init.d/redis-server stop
/etc/init.d/redis-server start
/etc/init.d/redis-server restart
/etc/init.d/redis restart

Mena kua whakauruhia e koe te redis mai i te waehere puna, ka taea e koe te whakaara ano i te redis ma te whakahau kati o te redis client program redis-cli:
redis-cli -h 127.0.0.1 -p 6379 shutdown

Mena kaore tetahi o nga tikanga o runga ake nei e angitu ki te aukati i te redis, ka taea e koe te whakamahi i te patu mutunga:
kill -9

[Tirohia te tono tauwāhi kōnae]

Tirohia kei hea te konae whirihoranga PHP:
Whakamahia te phpinfo ki te kite mena ka rahuitia te mahi, mahia i raro i te anga
php -v / -name php.ini
或者
find / -name php.ini

I te nuinga o te waa, ka whakauruhia te linux, ka kore te wget e whakauruhia ma te taunoa.
yum tāuta
yum -y install wget

Kei te haere te whakamohoatanga aunoa o te punaha, kua maukati te yum.
Ka taea e koe te kati i te tukanga yum:
rm -f /var/run/yum.pid

Takina mo te perl...Kaore a Perl i kitea i to punaha: Tena koa whakauruhia te perl ka whakamatau again
Ko te tikanga, me whakauru te perl. Ko te whakahau whakauru perl e whai ake nei:
yum -y install perl perl*

[Nga whakahau SSH mo te paewhiri mana Kloxo-MR]

I te wa e whakauru ana i te kaupapa, i te mono ranei, ka rahua "Kaore e taea te hanga whaiaronga"
Rongoā: huri ano i nga whakaaetanga o te mono kaupapa wp me te tukuake kōpaki
Mo te haumarutanga o te tūmau, 777 nga whakaaetanga kaore e taea te hoatu katoa, na te mea ka tukuna enei raarangi 755 whakaaetanga, ko te rangatira anake te whakaaetanga ki te tuhi.

Mena ka whakahaere koe i te whakahau e whai ake nei:
sh /script/fix-chownchmod

Ka ngana a Kloxo-MR ki te whakahou i te mana pupuri me nga whakaaetanga mo nga konae me nga raarangi i te pakiaka tuhinga o te waahi

Paewhiri Mana Kloxo-MR: Haere ki te "admin> Server> (localhost)> IP Wāhitau> Pānuihia IP".

Whakahoutanga tūmau
Whakahoutia te tūmau ki te putanga hōu
yum -y update

He maha nga wa i whakamatauria ai te tikanga i runga ake nei, engari he raru tonu, whakauruhia te whakahau whakatika e whai ake nei:
yum clean all; yum update -y; sh /script/cleanup

(I roto i te whakahoutanga o te hotaka, haere ki te kai i muri i etahi wa ka hoki mai ki te tirotiro, whakamauufo.org.in, img.ufoKua hoki mai nga wharangi .org.in ki te tikanga)

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

Hei whakarite kia tuhia e nga dns nga "tatauranga", i muri i te whakahou i te yum ma katoa; yum whakahou -y; sh /script/cleanup, kia rere:
sh /script/fixdnsaddstatsrecord

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

Tāuta anō Kloxo-MR:
Mena karekau he hapa, whakamatauria te whakahau e whai ake nei:
sh /script/upcp -y
