1、安裝redis

第一步：下載redis安裝包

wget http://download.redis.io/releases/redis-4.0.6.tar.gz

[root@iZwz991stxdwj560bfmadtZ local]# wget http://download.redis.io/releases/redis-4.0.6.tar.gz --2017-12-13 12:35:12-- http://download.redis.io/releases/redis-4.0.6.tar.gz Resolving download.redis.io (download.redis.io)... 109.74.203.151 Connecting to download.redis.io (download.redis.io)|109.74.203.151|:80... connected. HTTP request sent, awaiting response... 200 OK Length: 1723533 (1.6M) [application/x-gzip] Saving to: ‘redis-4.0.6.tar.gz’100%[==========================================================================================================>] 1,723,533 608KB/s in 2.8s 2017-12-13 12:35:15 (608 KB/s) - ‘redis-4.0.6.tar.gz’ saved [1723533/1723533]

?

第二步：解壓壓縮包

tar -zxvf?redis-4.0.6.tar.gz

[root@iZwz991stxdwj560bfmadtZ local]# tar -zxvf redis-4.0.6.tar.gz

第三步：yum安裝gcc依賴

yum install gcc

[root@iZwz991stxdwj560bfmadtZ local]# yum install gcc　　
遇到選擇,輸入y即可

第四步：跳轉到redis解壓目錄下

cd redis-4.0.6

[root@iZwz991stxdwj560bfmadtZ local]# cd redis-4.0.6

第五步：編譯安裝

make MALLOC=libc　　

[root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# make MALLOC=libc

將/usr/local/redis-4.0.6/src目錄下的文件加到/usr/local/bin目錄

cd src && make install

[root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# cd src && make install CC Makefile.depHint: It's a good idea to run 'make test' ;) INSTALL installINSTALL installINSTALL installINSTALL installINSTALL install

第六步：測試是否安裝成功?

先切換到redis src目錄下

[root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# cd src

1、直接啟動redis

./redis-server　

[root@iZwz991stxdwj560bfmadtZ src]# ./redis-server 18685:C 13 Dec 12:56:12.507 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo 18685:C 13 Dec 12:56:12.507 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=18685, just started 18685:C 13 Dec 12:56:12.507 # Warning: no config file specified, using the default config. In order to specify a config file use ./redis-server /path/to/redis.conf _._ _.-``__ ''-._ _.-`` `. `_. ''-._ Redis 4.0.6 (00000000/0) 64 bit.-`` .-```. ```\/ _.,_ ''-._ ( ' , .-` | `, ) Running in standalone mode|`-._`-...-` __...-.``-._|'` _.-'| Port: 6379| `-._ `._ / _.-' | PID: 18685`-._ `-._ `-./ _.-' _.-' |`-._`-._ `-.__.-' _.-'_.-'| | `-._`-._ _.-'_.-' | http://redis.io `-._ `-._`-.__.-'_.-' _.-' |`-._`-._ `-.__.-' _.-'_.-'| | `-._`-._ _.-'_.-' | `-._ `-._`-.__.-'_.-' _.-' `-._ `-.__.-' _.-' `-._ _.-' `-.__.-' 18685:M 13 Dec 12:56:12.508 # WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128. 18685:M 13 Dec 12:56:12.508 # Server initialized 18685:M 13 Dec 12:56:12.508 # WARNING overcommit_memory is set to 0!

Redis must be restarted after THP is disabled. 18685:M 13 Dec 12:56:12.508 * Ready to accept connections　

如上圖：redis啟動成功，但是這種啟動方式需要一直打開窗口，不能進行其他操作，不太方便。

按 ctrl + c可以關閉窗口。

2、以后臺進程方式啟動redis

第一步：修改redis.conf文件

將

daemonize no　　

修改為

daemonize yes

第二步：指定redis.conf文件啟動

./redis-server /usr/local/redis-4.0.6/redis.conf [root@iZwz991stxdwj560bfmadtZ src]# ./redis-server /usr/local/redis-4.0.6/redis.conf 18713:C 13 Dec 13:07:41.109 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo 18713:C 13 Dec 13:07:41.109 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=18713, just started 18713:C 13 Dec 13:07:41.109 # Configuration loaded

第三步：關閉redis進程

首先使用ps -aux | grep redis查看redis進程

[root@iZwz991stxdwj560bfmadtZ src]# ps -aux | grep redis root 18714 0.0 0.1 141752 2008 ? Ssl 13:07 0:00 ./redis-server 127.0.0.1:6379 root 18719 0.0 0.0 112644 968 pts/0 R+ 13:09 0:00 grep --color=auto redis

使用kill命令殺死進程

[root@iZwz991stxdwj560bfmadtZ src]# kill -9 18714

第七步：設置redis開機自啟動

1、在/etc目錄下新建redis目錄

mkdir redis

[root@iZwz991stxdwj560bfmadtZ etc]# mkdir redis

2、將/usr/local/redis-4.0.6/redis.conf 文件復制一份到/etc/redis目錄下，并命名為6379.conf　　

[root@iZwz991stxdwj560bfmadtZ redis]# cp /usr/local/redis-4.0.6/redis.conf /etc/redis/6379.conf

　　

3、將redis的啟動腳本復制一份放到/etc/init.d目錄下

[root@iZwz991stxdwj560bfmadtZ init.d]# cp /usr/local/redis-4.0.6/utils/redis_init_script /etc/init.d/redisd

4、設置redis開機自啟動

先切換到/etc/init.d目錄下

然后執行自啟命令

[root@iZwz991stxdwj560bfmadtZ init.d]# chkconfig redisd on service redisd does not support chkconfig　

看結果是redisd不支持chkconfig

解決方法：

使用vim編輯redisd文件，在第一行加入如下兩行注釋，保存退出

# chkconfig: 2345 90 10 # description: Redis is a persistent key-value database

注釋的意思是，redis服務必須在運行級2，3，4，5下被啟動或關閉，啟動的優先級是90，關閉的優先級是10。

再次執行開機自啟命令，成功

[root@iZwz991stxdwj560bfmadtZ 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　　

[root@izwz991stxdwj560bfmadtz ~]# service redisd start Starting Redis server... 2288:C 13 Dec 13:51:38.087 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo 2288:C 13 Dec 13:51:38.087 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=2288, just started 2288:C 13 Dec 13:51:38.087 # Configuration loaded

關閉：

service redisd stop

[root@izwz991stxdwj560bfmadtz ~]# service redisd stop Stopping ... Redis stopped

如果出現如下問題：

[root@iZwz991stxdwj560bfmadtZ ~]# service redisd start /var/run/redis_6379.pid exists, process is already running or crashed　　

Ubuntu下可能會沒有chkconfig命令，可以用以下命令替換使用：

root@vmware01:/etc/init.d# apt-get install sysv-rc-conf

? sysv-rc-conf redisd on? ? ? ? ? ? ?#? 開機redisd服務自動啟動

?

如果出現：Failed to start redisd.service: Unit redisd.service not found. 要用systemctl daemon-reload這命令 輸入systemctl daemon-reload，再輸入service redisd start就可以了。 查看端口占用情況 ss -tanl 顯示127.0.0.1:6379，說明啟動成功了。
