linux下centos7.2下安裝redis 4.0.6
一、安裝redis
第一步(bu)：下載redis安裝包(bao)
wget //download.redis.io/releases/redis-4.0.6.tar.gz
[root@localhost ~]# wget http://download.redis.io/releases/redis-4.0.6.tar.gz

第(di)二步(bu)：解(jie)壓壓縮包
tar -zxvf redis-4.0.6.tar.gz
[root@localhost home]# tar -zxvf redis-4.0.6.tar.gz
第(di)三步：yum安裝gcc依賴(lai)
yum install gcc
[root@localhost home]# yum install gcc
遇到選(xuan)擇,輸(shu)入y即(ji)可(ke)
第四步：跳轉到redis解壓目錄(lu)下
cd redis-4.0.6
[root@localhost home]# cd redis-4.0.6
第五步(bu)：編譯安裝
make MALLOC=libc
[root@localhost 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(lu) cp –rf 就行
cd src && make install
[root@localhost 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
二、啟動redis的三種方式
先切換到redis src目錄下
[root@localhost redis-4.0.6]# cd src
1、直接啟動redis
./redis-server
[root@localhost 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

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.

如上圖(tu)：redis啟動(dong)成功，但是這種(zhong)啟動(dong)方式(shi)需要一(yi)直打開窗口，不能進行其他操作，不太方便。
按 ctrl + c可以(yi)關(guan)閉窗口。
2、以后臺進程(cheng)方式啟動redis
第一(yi)步：修改redis.conf文件
將
daemonize no
修改為
daemonize yes
第二步：指(zhi)定redis.conf文(wen)件啟動
|
1 |
./redis-server /usr/local/redis-4.0.6/redis.conf |
[root@localhost 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(shou)先使用(yong)ps -aux | grep redis查看redis進程
[root@localhost 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(shi)用kill命令殺死(si)進程
[root@localhost src]# kill 18714
3、設置(zhi)redis開機自啟(qi)動
1、在/etc目錄下新建redis目(mu)錄
mkdir redis
[root@localhost etc]# mkdir redis
2、將/usr/local/redis-4.0.6/redis.conf 文件復制(zhi)一份到/etc/redis目錄(lu)下，并命名(ming)為6379.conf
[root@localhost redis]# cp /usr/local/redis-4.0.6/redis.conf /etc/redis/6379.conf
3、將redis的啟動腳(jiao)本復(fu)制一份放到(dao)/etc/init.d目錄下(xia)
[root@localhost 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(qi)命令
[root@localhost init.d]# chkconfig redisd on
service redisd does not support chkconfig
看結(jie)果(guo)是redisd不支持chkconfig
解(jie)決方法(fa)：
使用vim編(bian)輯redisd文(wen)件，在第一行(xing)加(jia)入如下兩行(xing)注釋(shi)，保存(cun)退出
# chkconfig: 2345 90 10
# description: Redis is a persistent key-value database
注釋(shi)的意思是，redis服務(wu)必(bi)須在運行級2，3，4，5下(xia)被(bei)啟動或關閉(bi)，啟動的優先級是90，關閉的優先級是10。
再次執行開機自啟(qi)命令，成功
[root@localhost init.d]# chkconfig redisd on
現在(zai)可以直接已服(fu)務的(de)形式啟動和關閉redis了
啟動：
service redisd start
[root@localhost ~]# 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：
方(fang)法1：service redisd stop
[root@localhost ~]# service redisd stop
Stopping ...
Redis stopped
方法(fa)2：redis-cli SHUTDOWN
三(san)、linux服務器端可以連接而遠程無法連接的原因(yin)
[root@localhost src]# vim ../redis.conf
把protected-mode yes改為protected-mode no（在沒有密碼的情況下(xia)，關閉保護模式）
注釋掉(diao)bind 127.0.0.1 （取消綁(bang)定(ding)本地地址(zhi)）
把daemonize no改為(wei)daemonize yes （是否為進程(cheng)守護，關閉ssh窗口后(hou)即(ji)是否在(zai)后(hou)臺(tai)繼續運行）
在(zai)redis-conf注(zhu)釋掉(diao)bind 127.0.0.1 （取消綁定本地地址(zhi)）
若還不能(neng)訪(fang)問 則開(kai)啟(qi)制定端口號或者關(guan)閉防火墻，在這(zhe)采用關(guan)閉防火墻，由于是(shi)centos7，防火(huo)墻進行了升(sheng)級
systemctl stop firewalld.service #停止(zhi)firewall
systemctl disable firewalld.service ;#禁(jin)止firewall開機啟(qi)動
如果出現如下問題：
[root@localhost ~]# service redisd start
/var/run/redis_6379.pid exists, process is already running or crashed
刪除redis_6379.pid即可
