CENTOS7下安裝REDIS
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
| 1 2 3 4 5 6 7 8 9 10 11 |
[root@iZwz991stxdwj560bfmadtZ local]# wget http://download.redis.io/releases/redis-4.0.6.tar.gz

|
第二步：解壓壓縮包
tar -zxvf redis-4.0.6.tar.gz
| 1 |
[root@iZwz991stxdwj560bfmadtZ local]# tar -zxvf redis-4.0.6.tar.gz
|
第三步：yum安裝gcc依賴
yum install gcc
| 1 |
[root@iZwz991stxdwj560bfmadtZ local]# yum install gcc |
| 1 |
遇到選擇,輸入y即可<br><br><br>
|
第四步：跳轉到redis解壓目錄下
cd redis-4.0.6
| 1 |
[root@iZwz991stxdwj560bfmadtZ local]# cd redis-4.0.6
|
第五步：編譯安裝
make MALLOC=libc
| 1 |
[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
| 1 2 3 4 5 6 7 8 9 10 |
[root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# 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
|
第六步：測試是否安裝成功
先切換到redis src目錄下
| 1 |
[root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# cd src
|
1、直接啟動redis
./redis-server
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 |
[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 must be restarted after THP is disabled.

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、以後臺進程方式啟動redis
第一步：修改redis.conf文件
將
| 1 |
daemonize no
|
修改為
| 1 |
daemonize yes
|
第二步：指定redis.conf文件啟動
| 1 |
./redis-server /usr/local/redis-4.0.6/redis.conf
|
| 1 2 3 4 |
[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
| 1 2 3 |
[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
| 1 |
[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
| 1 |
[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，並命名為6379.conf
| 1 |
[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
| 1 |
[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
然後執行自啟命令
| 1 2 |
[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註釋，保存退出
| 1 2 |
# chkconfig: 2345 90 10
# description: Redis is a persistent key-value database
|
註釋的意思是，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
| 1 |
[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
| 1 2 3 4 5 |
[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
| 1 2 3 |
[root@izwz991stxdwj560bfmadtz ~]# service redisd stop
Stopping ...
Redis stopped
|

如果出現如下問題：
| 1 2 |
[root@iZwz991stxdwj560bfmadtZ ~]# service redisd start
/var/run/redis_6379.pid exists, process is already running or crashed
|
可參考資料：http://blog.csdn.net/luozhonghua2014/article/details/54649295
命令;service redis start
/var/redis/run/redis_6379.pid exists, process is already running or crashed
引起這類問題一般都是強制關掉電源或斷電造成的，也是沒等linux正常關機
科學的處理辦法2種
1：可用安裝文件啟動 redis-server /etc/redis/6379.conf
2：shutdown -r now 軟重啟讓系統自動恢復下就行了
註：網上的說法不可取，不要改動任何文件，其實什麽配置等變化都沒有
