Troubleshoot Redis neeg rau zaub mov pib tsis ua hauj lwm: daws teeb meem ntawm kev rov pib dua thiab tsis tuaj yeem tau txais kev sib txuas ntawm cov chaw taws teeb

Kuv tau teeb tsa Redis server rau ntawm lub tshuab CentOS 7 tshiab , tab sis kuv tsis tuaj yeem pib nws siv systemctl.

Sim pib qhov kev pabcuam Redis ▼

systemctl start redis.service

• Redis ua tsis tau tejyam pib (tsis muaj cov zis).

Nov yog qhov tshwm sim thaum sim txuas rau Redis:

redis-cli
Could not connect to Redis at 127.0.0.1:6379: Connection refused
not connected>

Tab sis pib Redis manually ua haujlwm:

[root@redis ~]# redis-cli
127.0.0.1:6379>

Query Redis xwm txheej, nws qhia tau tias Redis tsis qhib ▼

[root@redis ~]# systemctl status redis.service
redis-server.service - Redis persistent key-value database
Loaded: loaded (/usr/lib/systemd/system/redis-server.service; disabled)
Active: inactive (dead)

November 25 18:52:16 redis systemd[1]: Starting Redis persistent key-value database...
November  25 18:52:16 redis systemd[1]: Started Redis persistent key-value database.

Cov hauv qab no yog lwm cov lus nug los nug cov xwm txheej ntawm Redis, uas qhia txog qhov piv txwv ntawm Redis tsis ua haujlwm ▼

daws qhov teeb meem uas Redis server tsis pib

Txhawm rau khiav qhov tseeb version ntawm Redis nrog systemd, koj yuav tsum hloov kho Redis cov ntaub ntawv teeb tsa:

/etc/redis.conf

Tsim thiab teeb tsa Redis nrog kev txhawb nqa systemd ▼

daemonize no

supervised auto

Kuv yuav ua li cas yog tias Redis tsis tuaj yeem tau txais kev sib txuas hauv thaj chaw deb tom qab rov pib VPS server?

Yog tias koj rov pib dua VPS neeg rau zaub mov, Redis tsis tuaj yeem pib tau txais kev sib txuas hauv thaj chaw deb, koj tuaj yeem tshem tawm cov ntaub ntawv dump.rdb (nco snapshot) ▼

cd /var/lib/redis
mv dump.rdb dump.rdb_bak

Xyuas seb qhov kev pabcuam Redis puas tau pib ▼

ps -ef|grep redis

• Sim rov pib dua VPS server Yog tias Redis tuaj yeem pib li qub, nws txhais tau hais tias Redis cov ntaub ntawv teeb tsa tsuas yog kho ua haujlwm.
