centos7.5 安装 redis-4.0.11

Posted 2021-01-18 BrokenColor

1.下载redis包

wget wget http://download.redis.io/releases/redis-4.0.11.tar.gz

2.解压安装

#解压
tar zxvf redis-4.0.11.tar.gz
#安装
 cd redis-4.0.11
#执行make

#执行make时报错：/bin/sh: cc: command not found--如果没报错可跳过

sudo yum -y install gcc gcc-c++ libstdc++-devel

##报错
# make[1]: Entering directory `/opt/redis-2.6.14/src‘
# CC adlist.o
# In file included from adlist.c:34:
# zmalloc.h:50:31: error: jemalloc/jemalloc.h: No such file or directory
# zmalloc.h:55:2: error: #error "Newer version of jemalloc required"
# make[1]: *** [adlist.o] Error 1
# make[1]: Leaving directory `/opt/redis-2.6.14/src‘
# make: *** [all] Error 2

#执行
make MALLOC=libc
#执行完上面的命令后，系统提示 ‘Hint: To run ‘make test‘ is a good idea‘

make test #报错: You need tcl 8.5 or newer in order to run the Redis test

#安装tcl
sudo yum install tcl

继续执行

[[email protected] redis-4.0.11]# cd src && make install

#Hint: It‘s a good idea to run ‘make test‘ ;)

#   INSTALL install
#    INSTALL install
#    INSTALL install
#    INSTALL install
#    INSTALL install

#看到显示INSTALL install说明成功

3.验证启动redis-server

换到redis src目录下
 cd src
 ./redis-server

4.配置

（1）配置为redis-server守护进程（即启动不会被redis-server占用窗口导致我们无法干别的事情）

#修改redis.conf  
[[email protected] src]# cd ..
[[email protected] redis-4.0.11]# vim redis.conf 
#可通过查询命令：/daemonize 进行快速定位
daemonize yes　　 # 守护进程模式开启


[[email protected] redis-4.0.11]# cd src/
[[email protected] src]# ./redis-server ../redis.conf
#7976:C 07 Nov 10:52:22.184 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
#7976:C 07 Nov 10:52:22.184 # Redis version=4.0.11, bits=64, commit=00000000, modified=0, pid=7976, just started
#7976:C 07 Nov 10:52:22.184 # Configuration loaded

#查看时候启动
[[email protected] src]# ps -aux|grep redis
#root       2835  0.0  0.1 150932  1540 pts/0    T    09:46   0:00 wget http://download.redis.io/releases/redis-4.0.11.tar.gz
#root       7977  0.0  0.2 141836  2040 ?        Ssl  10:52   0:00 ./redis-server 127.0.0.1:6379
#root       7982  0.0  0.0 112720   984 pts/0    R+   10:53   0:00 grep --color=auto redis

（2）设置redis开机自启动

#使用kill命令杀死进程
[[email protected] redis-4.0.11]#  kill -9 7977

#设置redis开机自启动
[[email protected] etc]# mkdir redis
[[email protected] redis-4.0.11]# cp redis.conf /etc/redis/6379.conf
[[email protected] redis-4.0.11]# cp utils/redis_init_script /etc/init.d/redisd
[[email protected] redis-4.0.11]# cd /etc/init.d/
[[email protected] init.d]# chkconfig redisd on

#service redisd does not support chkconfig

#解决方法：
#使用vim编辑redisd文件，在第一行加入如下两行注释，保存退出

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

#注释的意思是，redis服务必须在运行级2，3，4，5下被启动或关闭，启动的优先级是90，关闭的优先级是10。

[[email protected] var]# service redisd start
#报错： /var/run/redis_6379.pid exists, process is already running or crashed
#[重要]如果是没有数据的情况下
[[email protected] var]# rm /var/run/redis_6379.pid
[[email protected] redis]# service redisd start
#Starting Redis server...
#8206:C 07 Nov 11:31:26.807 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
#8206:C 07 Nov 11:31:26.807 # Redis version=4.0.11, bits=64, commit=00000000, modified=0, pid=8206, just started
#8206:C 07 Nov 11:31:26.807 # Configuration loaded
[[email protected] redis]# ps -aux|grep redis
#root       8207  0.0  0.1  38240  1988 ?        Ssl  11:31   0:00 /usr/local/bin/redis-server 127.0.0.1:6379
#root       8212  0.0  0.0 112720   984 pts/0    R+   11:31   0:00 grep --color=auto redis

测试一下redis-cli

#客户端测试
[[email protected] redis]# cd /soft/redis-4.0.11
[[email protected] redis-4.0.11]# cd src/
[[email protected] src]# ./redis-cli 
127.0.0.1:6379> set "a" "valueA"
#OK
127.0.0.1:6379> get "a"
#"valueA"
