This article mainly introduces "how to install and configure Redis service under CentOS7". In daily operation, I believe many people have doubts about how to install and configure Redis service under CentOS7. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubt of "how to install and configure Redis service under CentOS7". Next, please follow the editor to study!

1. Installation depends on ➜yum install-y gcc gcc-c++ kernel-devel2. Download the source code package # it is recommended to store the source code of each software in this directory ➜cd / usr/local/src# download the specified version➜ wget http://download.redis.io/releases/redis-5.0.5.tar.gz# download the latest stable version ➜wget http://download.redis.io/redis-stable.tar.gz# to view the specific version of the source code➜ cat redis-stable/src/version.h3. Compile and install ➜tar zxvf redis-5.0.5.tar.gz➜ cd redis-5.0.5 ➜make# install to the specified directory➜ make PREFIX=/usr/local/redis-5.0.5 install# copy the default configuration file to the specified directory ➜mkdir / usr/local/redis-5.0.5/etc➜ cp redis.conf / usr/local/redis-5.0.5/etc/# creator soft link To update the cd / usr/local/ln-s redis-5.0.5 redis# configuration environment variables in a later version, to verify ➜redis-cli-vredis-cli 5.0.54 globally using the Redis-related command➜ echo 'export PATH= "$PATH:/usr/local/redis/bin" > / etc/profile ➜source / etc/profile#. Modify the default profile

Here are just some recommended basic configurations

➜cd / usr/local/redis/etc# to facilitate the management of multiple Redis services Use the version number as the name suffix of the configuration file ➜mv redis.conf redis_6379.conf# to start editing the configuration file➜ vi redis_6379.conf#-# the following are common configuration items #-# run the daemonize yes# process in daemon (background) mode The file pidfile / var/redis/run/redis_6379.pid# allows only specified host connections By default, there is no limit on how long the client will be idle (in s) with bind 127.0.0.The port 637 clients will be idle # default 0, unlimited timeout 30 local persistent data filename dbfilename dump_6379.rdb# setting working directory dir / var/redis/db/# log level #-debug is suitable for development and testing, printing more information #-verbose is simpler than debug #-notice default Ordinary verbose, for production environment #-warning warnings and some serious information loglevel notice# log file # is an empty string by default, indicating standard output (stdout) # if running as a daemon and standard output is used here, the log is sent to the / dev/nulllogfile / var/redis/log/redis_6379.log# client connection password # to ensure service security It is recommended to open and set a complex password requirepass pwd2019#-# save the above modified configuration file #-# create a directory ➜mkdir-p / var/redis/ {run,log,db} 5 that does not exist in the configuration. Start the service

In CentOS7+, it is recommended to use the systemctl command for unified management of Redis services, as follows:

# check service status ➜systemctl status redis_6379 ● redis_6379.service-LSB: Redis data structure server Loaded: loaded (/ etc/rc.d/init.d/redis_6379; bad; vendor preset: disabled) Active: active (running) since Mon 2019-11-11 02:21:03 UTC 3s ago Docs: man:systemd-sysv-generator (8) Process: 1042 ExecStop=/etc/rc.d/init.d/redis_6379 stop (code=exited, status=0/SUCCESS) Process: 1056 ExecStart=/etc/rc.d/init.d/redis_6379 start (code=exited Status=0/SUCCESS) CGroup: / system.slice/redis_6379.service └─ 1058 / usr/local/redis/bin/redis-server 127.0.0.1:6379Nov 11 02:21:03 cnetos7-localhost systemd [1]: Starting LSB: Redis data structure server...Nov 11 02:21:03 cnetos7-localhost redis_6379 [1056]: Starting Redis server...Nov 11 02:21:03 cnetos7-localhost redis_6379 [1056]: 1057 Nov 11 Nov 2019 02 CGroup 21 CGroup 03.594 # oO0OoO0OoO0Oo Re...0OoNov 11 02:21:03 cnetos7-localhost redis_6379 [1056]: 1057:C 11 Nov 2019 02:21:03.594 # Redis version=5....tedNov 11 02:21:03 cnetos7-localhost redis_6379 [1056]: 1057:C 11 Nov 2019 02:21:03.594 # Configuration loadedNov 11 02:21:03 cnetos7-localhost systemd [1]: Started LSB: Redis data structure server.Hint: Some lines were ellipsized Use-l to show in full.# startup service ➜systemctl start redis_6379# shutdown service➜ systemctl stop redis_6379 to this point The study on "how to install and configure Redis services under CentOS7" is over.
