## 第一种最简启动 启动服务端 ~~~ redis-server //默认使用6379端口 ~~~ 打开另一个ssh终端,用客户端进行连接 ~~~ redis-cli -h 127.0.0.1 -p 6379 ~~~ 连接成功 ~~~ [root@localhost ~]# redis-cli -h 127.0.0.1 -p 6379 127.0.0.1:6379> ~~~ ## 第二种(动态参数) 服务端使用6380端口 ~~~ redis-server --port 6380 //指定使用6380端口启动redis ~~~ 客户端 ~~~ redis-cli -p 6380 ~~~ ## 第三种使用配置文件的方式启动(生产环境) 单机多实例配置文件可以用端口区分开. 进入Redis安装目录, 创建confing文件夹 . 拷贝redis.conf文件至config文件 . 因为Redis是单线程的,但是我们服务器基本都是多核的,所以我们经常在一台服务器上部署很多的Redis . 这样我们就需要配置很多的端口 . 这样我们的配置文件就以端口来进行区分 . 比如将redis.conf文件名修改成redis-6381 . ~~~ cat redis-6381 | grep -v "#" |grep -v "^$" > redis-6382 //对原6381文件进行"#"注释行进行过滤并重定向 为redis-6382 ~~~ 得到配置文件 ~~~ daemonize no pidfile /var/run/redis.pid //这里为进程存放的位置 port 6379 tcp-backlog 511 timeout 0 tcp-keepalive 0 loglevel notice logfile "" databases 16 save 900 1 save 300 10 save 60 10000 stop-writes-on-bgsave-error yes rdbcompression yes rdbchecksum yes dbfilename dump.rdb dir ./ slave-serve-stale-data yes slave-read-only yes repl-diskless-sync no repl-diskless-sync-delay 5 repl-disable-tcp-nodelay no slave-priority 100 appendonly no appendfilename "appendonly.aof" appendfsync everysec no-appendfsync-on-rewrite no auto-aof-rewrite-percentage 100 auto-aof-rewrite-min-size 64mb aof-load-truncated yes lua-time-limit 5000 slowlog-log-slower-than 10000 slowlog-max-len 128 latency-monitor-threshold 0 notify-keyspace-events "" hash-max-ziplist-entries 512 hash-max-ziplist-value 64 list-max-ziplist-entries 512 list-max-ziplist-value 64 set-max-intset-entries 512 zset-max-ziplist-entries 128 zset-max-ziplist-value 64 hll-sparse-max-bytes 3000 activerehashing yes client-output-buffer-limit normal 0 0 0 client-output-buffer-limit slave 256mb 64mb 60 client-output-buffer-limit pubsub 32mb 8mb 60 hz 10 aof-rewrite-incremental-fsync yes ~~~ 修改为以下 ~~~ daemonize yes //修改为yes, 以守护进程的方式进行启动 port 6382 //端口号修改为6382 dir "/opt/soft/redis/data" //工作目录,就是我们的日志文件和持久化的文件存在哪个目录 logfile "6382.log" //日志文件 logfile //redis系统日志,只是一个文件名 ~~~ 启动 ~~~ redis-server config/redis-6382 ~~~ 查看进程是否存在 ~~~ ps -ef | grep 6382 ~~~ 结果,说明启动成功 ~~~ root 18534 1 0 00:41 ? 00:00:00 redis-server *:6382 root 18538 18300 0 00:41 pts/0 00:00:00 grep --color=auto 6382 ~~~ 客户端连接成功 ~~~ redis-cli -p 6382 127.0.0.1:6382> ~~~ 查看日志文件 ~~~ 18552:M 29 Mar 00:44:52.035 * Increased maximum number of open files to 10032 (it was originally set to 1024). _._ _.-``__ ''-._ _.-`` `. `_.
