CENTOS7下安裝REDIS

編譯安裝 warn borde 現在 stop with cannot 科學 to do

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 --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

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 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! 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. 18685:M 13 Dec 12:56:12.508 # 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. 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、以後臺進程方式啟動redis

第一步:修改redis.conf文件

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。

技術分享圖片

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

2、http://blog.csdn.net/gxw19874/article/details/51992125

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
