Centos-7.4_安裝_Redis_4.0.8
一、安裝redis
第一步：下載redis安裝包
[[email protected] ~]# mkdir /usr/local/redis/ --建立目錄
[[email protected] redis]# cd /usr/local/redis/ --進入當前目錄
[[email protected] ~]# wget http://download.redis.io/releases/redis-4.0.8.tar.gz --下載軟體包
--2018-12-30 12:20:30-- http://download.redis.io/releases/redis-4.0.8.tar.gz

2018-12-30 12:20:32 (841 KB/s) - 已儲存 “redis-4.0.8.tar.gz” [1729973/1729973])
第二步：解壓壓縮包
[[email protected] redis]# tar -zxvf redis-4.0.8.tar.gz
第三步：yum安裝gcc依賴
[[email protected] redis]# yum -y install gcc-*
第四步：跳轉到redis解壓目錄下
[[email protected] redis]# cd redis-4.0.8/
第五步：編譯安裝
[[email protected] redis]# make MALLOC=libc
將/usr/local/redis-4.0.8/src目錄下的檔案加到/usr/local/bin目錄
cd src && make install
[[email protected] redis-4.0.8]# cd src && make install
CC Makefile.dep
Hint: It's a good idea to run 'make test' ;)
INSTALL install
INSTALL install
INSTALL install
INSTALL install
INSTALL install
二、啟動redis的三種方式
先切換到redis src目錄下
[[email protected] redis-4.0.8]# cd src/
1、直接啟動redis
[[email protected] src]# ./redis-server
35611:C 30 Dec 12:16:11.035 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
35611:C 30 Dec 12:16:11.036 # Redis version=4.0.8, bits=64, commit=00000000, modified=0, pid=35611, just started
35611:C 30 Dec 12:16:11.036 # Warning: no config file specified, using the default config. In order to specify a config file use ./redis-server /path/to/redis.conf
35611:M 30 Dec 12:16:11.036 * Increased maximum number of open files to 10032 (it was originally set to 1024).

35611:M 30 Dec 12:16:11.037 # WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.

35611:M 30 Dec 12:16:11.037 # 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.
35611:M 30 Dec 12:16:11.037 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.
35611:M 30 Dec 12:16:11.037 * Ready to accept connections
如上圖：redis啟動成功，但是這種啟動方式需要一直開啟視窗，不能進行其他操作，不太方便。
按 ctrl + c可以關閉視窗。
2、以後臺程序方式啟動redis
第一步：修改redis.conf檔案
[[email protected] src]# vim /usr/local/redis/redis-4.0.8/redis.conf
將
daemonize no
修改為
daemonize yes
第二步：指定redis.conf檔案啟動
[[email protected] src]# ./redis-server /usr/local/redis/redis-4.0.8/redis.conf
45390:C 30 Dec 12:42:32.886 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
45390:C 30 Dec 12:42:32.886 # Redis version=4.0.8, bits=64, commit=00000000, modified=0, pid=45390, just started
45390:C 30 Dec 12:42:32.886 # Configuration loaded
第三步：關閉redis程序
首先使用ps -aux | grep redis檢視redis程序
[[email protected] src]# ps -aux | grep redis
root 45391 0.0 0.0 141816 2004 ? Rsl 12:42 0:00 ./redis-server 127.0.0.1:6379
使用kill命令殺死程序
[[email protected] src]# kill -9 45391
3、設定redis開機自啟動
1、在/etc目錄下新建redis目錄
mkdir redis
[[email protected] src]# mkdir /etc/redis
2、將/usr/local/redis/redis-4.0.8/redis.conf 檔案複製一份到/etc/redis目錄下，並命名為6379.conf
[[email protected] src]# cp /usr/local/redis/redis-4.0.8/redis.conf /etc/redis/6379.com
3、將redis的啟動指令碼複製一份放到/etc/init.d目錄下
[[email protected] src]# cp /usr/local/redis/redis-4.0.8/utils/redis_init_script /etc/init.d/redisd
4、設定redis開機自啟動
先切換到/etc/init.d目錄下
然後執行自啟命令
[[email protected] init.d]# chkconfig redisd on
服務 redisd 不支援 chkconfig
看結果是redisd不支援chkconfig
解決方法：
使用vim編輯redisd檔案，在第一行加入如下兩行註釋，儲存退出
註釋的意思是，redis服務必須在執行級2，3，4，5下被啟動或關閉，啟動的優先順序是90，關閉的優先順序是10。
再次執行開機自啟命令，成功
[[email protected] init.d]# chkconfig redisd on
現在可以直接已服務的形式啟動和關閉redis了
啟動：
service redisd start
如果出現如下問題：
[[email protected] ~]# service redisd start
Please use start or stop as first argument
可用安裝檔案啟動 redis-server /etc/redis/6379.conf
[[email protected] ~]# redis-server /etc/redis/6379.conf

9562:C 30 Dec 13:44:57.160 # Redis version=4.0.8, bits=64, commit=00000000, modified=0, pid=9562, just started
