## 第一種最簡啟動 啟動服務端 ~~~ redis-server //默認使用6379端口 ~~~ 打開另一個ssh終端,用客戶端進行連接 ~~~ redis-cli -h 127.0.0.1 -p 6379 ~~~ 連接成功 ~~~ [root@localhost ~]# redis-cli -h 127.0.0.1 -p 6379 127.0.0.1:6379> ~~~ ## 第二種(動態參數) 服務端使用6380端口 ~~~ redis-server --port 6380 //指定使用6380端口啟動redis ~~~ 客戶端 ~~~ redis-cli -p 6380 ~~~ ## 第三種使用配置文件的方式啟動(生產環境) 單機多實例配置文件可以用端口區分開. 進入Redis安裝目錄, 創建confing文件夾 . 拷貝redis.conf文件至config文件 . 因為Redis是單線程的,但是我們服務器基本都是多核的,所以我們經常在一臺服務器上部署很多的Redis . 這樣我們就需要配置很多的端口 . 這樣我們的配置文件就以端口來進行區分 . 比如將redis.conf文件名修改成redis-6381 . ~~~ cat redis-6381 | grep -v "#" |grep -v "^$" > redis-6382 //對原6381文件進行"#"注釋行進行過濾并重定向 為redis-6382 ~~~ 得到配置文件 ~~~ daemonize no pidfile /var/run/redis.pid //這里為進程存放的位置 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 ~~~ 修改為以下 ~~~ daemonize yes //修改為yes, 以守護進程的方式進行啟動 port 6382 //端口號修改為6382 dir "/opt/soft/redis/data" //工作目錄,就是我們的日志文件和持久化的文件存在哪個目錄 logfile "6382.log" //日志文件 logfile //redis系統日志,只是一個文件名 ~~~ 啟動 ~~~ redis-server config/redis-6382 ~~~ 查看進程是否存在 ~~~ ps -ef | grep 6382 ~~~ 結果,說明啟動成功 ~~~ 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 ~~~ 客戶端連接成功 ~~~ 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). _._ _.-``__ ''-._ _.-`` `. `_.
