启动redis
redis可执行文件说明:
redis-server:redis服务器
redis-cli:redis命令行客户端
redis-benchmark:redis性能测试工具
redis-check-aof:aof文件修复工具
redis-check-dump:rdb文件检查工具
1、直接启动
直接运行redis-server即可以启动redis
redis服务器默认会使用6379端口,通过--port参数可以自定义端口号:
redis-server --port 6380
如果出现警告:
WARNING overcommit_memory is set to 0! Background save may fail under low memory condition.
To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
过量使用内存设置为0!在低内存环境下,后台保存可能失败。为了修正这个问题,请在/etc/sysctl.conf 添加一项 'vm.overcommit_memory = 1' ,然后重启(或者运行命令'sysctl vm.overcommit_memory=1' )使其生效。
按这个提示来做,警告排除。
2、通过初始化脚本启动redis
redis源码目录的utils文件夹中有一个名为redis-init_script的初始化脚本文件
步骤
(1)配置初始化脚本。
首先将初始化脚本复制到/etc/init.d目录中,文件名为redis_端口号(redis_6379),然后修改脚本第6行的REDISPORT的变量值为同样的端口号(ubuntu)
如果是centos或者redhat则使用以下脚本(端口号根据实际情况修改)
#chkconfig: 2345 90 10 #description: Redis is a persistent key-value database PATH=/usr/local/bin:/sbin:/usr/bin:/bin REDISPORT=6379 EXEC=/usr/local/bin/redis-server REDIS_CLI=/usr/local/bin/redis-cli PIDFILE=/var/run/redis_6379.pid CONF="/etc/redis/6379.conf" case "$1" in start) if [ -f $PIDFILE ] then echo "$PIDFILE exists, process is already running or crashed" else echo "Starting Redis server..." $EXEC $CONF fi if [ "$?"="0" ] then echo "Redis is running..." fi ;; stop) if [ ! -f $PIDFILE ] then echo "$PIDFILE does not exist, process is not running" else PID=$(cat $PIDFILE) echo "Stopping ..." $REDIS_CLI -p $REDISPORT SHUTDOWN while [ -x ${PIDFILE} ] do echo "Waiting for Redis to shutdown ..." sleep 1 done echo "Redis stopped" fi ;; restart|force-reload) ${0} stop ${0} start ;; *) echo "Usage: /etc/init.d/redis_6379 {start|stop|restart|force-reload}" >&2 exit 1 esac
(2)建立需要的文件夹
/etc/redis 存放redis配置文件
/var/redis/端口号 存放redis的持久化文件
(3)修改配置文件
把配置文件模板复制到/etc/redis目录中,已端口号命名(如“6379.conf”)
需要修改的配置及说明:
daemonize yes:使redis以守护进程模式运行
pidfile /var/run/redis_端口号.pid:设置redis的pid文件位置
port 端口号:设置redis监听的端口号
dir /var/redis/端口号:设置持久化文件存放位置
设置开机启动服务:
sudo update-rc.d redis_端口号 defaults // 告诉系统启动时候,自动执行redis_端口号 这个脚本。(ubuntu)

Redis goes beyond SQL databases because of its high performance and flexibility. 1) Redis achieves extremely fast read and write speed through memory storage. 2) It supports a variety of data structures, such as lists and collections, suitable for complex data processing. 3) Single-threaded model simplifies development, but high concurrency may become a bottleneck.

Redis is superior to traditional databases in high concurrency and low latency scenarios, but is not suitable for complex queries and transaction processing. 1.Redis uses memory storage, fast read and write speed, suitable for high concurrency and low latency requirements. 2. Traditional databases are based on disk, support complex queries and transaction processing, and have strong data consistency and persistence. 3. Redis is suitable as a supplement or substitute for traditional databases, but it needs to be selected according to specific business needs.

Redis is primarily a database, but it is more than just a database. 1. As a database, Redis supports persistence and is suitable for high-performance needs. 2. As a cache, Redis improves application response speed. 3. As a message broker, Redis supports publish-subscribe mode, suitable for real-time communication.

Redis is an open source memory data structure storage used as a database, cache and message broker, suitable for scenarios where fast response and high concurrency are required. 1.Redis uses memory to store data and provides microsecond read and write speed. 2. It supports a variety of data structures, such as strings, lists, collections, etc. 3. Redis realizes data persistence through RDB and AOF mechanisms. 4. Use single-threaded model and multiplexing technology to handle requests efficiently. 5. Performance optimization strategies include LRU algorithm and cluster mode.

Redis's functions mainly include cache, session management and other functions: 1) The cache function stores data through memory to improve reading speed, and is suitable for high-frequency access scenarios such as e-commerce websites; 2) The session management function shares session data in a distributed system and automatically cleans it through an expiration time mechanism; 3) Other functions such as publish-subscribe mode, distributed locks and counters, suitable for real-time message push and multi-threaded systems and other scenarios.
