一、redis安裝
[root@localhost ~]# yum install gcc gcc-c++ make -y
[root@localhost ~]# cd /opt/redis-5.0.4/
[root@localhost ~]# make #echo $?檢驗該命令是否執行成功
[root@localhost redis-5.0.4]# mkdir -p /data/redis/
[root@localhost redis-5.0.4]# make prefix=/data/redis install #echo $?檢驗該命令是否執行成功
[root@localhost redis-5.0.4]# mkdir /data/redis/conf
[root@localhost redis-5.0.4]# cp -p redis.conf /data/redis/conf/
二、生成的指令
[root@localhost redis-5.0.4]# cd /data/redis/bin/
[root@localhost bin]# ll
total 32700
-rwxr-xr-x. 1 root root 4366576 jun 20 16:25 redis-benchmark
-rwxr-xr-x. 1 root root 8101248 jun 20 16:25 redis-check-aof
-rwxr-xr-x. 1 root root 8101248 jun 20 16:25 redis-check-rdb
-rwxr-xr-x. 1 root root 4806800 jun 20 16:25 redis-cli
lrwxrwxrwx. 1 root root 12 jun 20 16:25 redis-sentinel -> redis-server
-rwxr-xr-x. 1 root root 8101248 jun 20 16:25 redis-server
三、啟動
[root@localhost bin]# /data/redis/bin/redis-server -h
[root@localhost bin]# /data/redis/bin/redis-server /data/redis/conf/redis.conf(此時服務已啟動,但程序未退出,重新開啟終端測試)
[root@localhost ~]# ps -ef | grep redis
root 12690 7705 0 16:27 pts/0 00:00:00 /data/redis/bin/redis-server 127.0.0.1:6379
root 12843 12714 0 16:30 pts/1 00:00:00 grep --color=auto redis
退出時,ctrl+c即可殺死程序,推出服務
若要程序一致執行,將程序放在後台使用
[root@localhost bin]# /data/redis/bin/redis-server /data/redis/conf/redis.conf &
關閉服務:
[root@localhost ~]# /data/redis/bin/redis-cli shutdown
[root@localhost ~]# ps -ef | grep redis
root 13012 12714 0 16:33 pts/1 00:00:00 grep --color=auto redis
四、調優
(1)核心引數
[root@localhost ~]# cat /proc/sys
sys/ sysrq-trigger sysvipc/
[root@localhost ~]# cat /proc/sys/net/core/somaxconn
128[root@localhost ~]# echo 1024 > /proc/sys/net/core/somaxconn
[root@localhost ~]# echo 1 > /proc/sys/vm/overcommit_memory
[root@localhost ~]# cat /sys/kernel/mm/transparent_hugepage/enabled
[always] madvise never
[root@localhost ~]# echo never > /sys/kernel/mm/transparent_hugepage/enabled
[root@localhost ~]# cat /sys/kernel/mm/transparent_hugepage/enabled
always madvise [never]
redis 安裝及配置介紹
1.2 解壓縮剛下好的redis包tar zxvf redis 5.0.3.tar.gz 1.3 進入剛才解壓好的redis資料夾中cd redis 5.0.3 1.4 make,友情提示,如果make被中斷,最好是刪除解壓好的資料夾,重新解壓縮一遍,否則可能make失敗 1.5 實驗啟動cd sr...

Redis安裝及配置啟動方式
一 redis安裝 2 將原始碼包解壓至 opt cd 桌面 sudo tar zxvf redis 3.2.9.tar.gz c opt 3 此時cd進入解壓目錄 4 在繼續往下執行make命令就能安裝,但是redis是 c語言開發,安裝redis需要先講原始碼進行編譯,編譯依賴gcc環境.gcc...
