腾讯云Centos7.2搭建redis5.0

安装

redis下载官网
1.下载解压包

wget http://download.redis.io/releases/redis-5.0.5.tar.gz

2.解压包

tar xzf redis-5.0.5.tar.gz

3.进入解压文件目录

cd redis-5.0.5

4.编译

make

出现问题

说明未安装gcc，使用命令安装gcc

yum install gcc

gcc安装完后make又出现了下面问题

原因是jemalloc重载了Linux下的ANSI C的malloc和free函数。解决办法：make时添加参数。

make MALLOC=libc

完成后进行，执行这个的目的就是将可执行文件拷贝到/usr/local/bin/目录下，这样就可以直接执行redis-server 、redis-cli 等命令了。

make install

5.查看版本

[[e-mail]_0_16_centos bin]# redis-server -v
Redis server v=5.0.5 sha=00000000:0 malloc=libc bits=64 build=57ca631c3a0a9413

6.启动服务

[[e-mail]_0_16_centos bin]# redis-server

Redis must be restarted after THP is disabled.

7.重新打开终端，插入数据进行测试

[[e-mail]_0_16_centos ~]# redis-cli
127.0.0.1:6379> set name zhangsan
OK
127.0.0.1:6379> get name
"zhangsan"
127.0.0.1:6379> keys *
1) "name"
127.0.0.1:6379> 

8.设置后台运行

[[e-mail]_0_16_centos redis]# mkdir /etc/redis
[[e-mail]_0_16_centos redis]# cp redis.conf /etc/redis
[[e-mail]_0_16_centos redis]# vim /etc/redis/redis.conf 

找到"daemonize no" no改为yes你可以在命令行模式下输入/进行查找


指定配置文件后台启动redis

[[e-mail]_0_16_centos redis]# redis-server /etc/redis/redis.conf 
22528:C 23 Jul 2019 10:00:13.732 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
22528:C 23 Jul 2019 10:00:13.732 # Redis version=5.0.5, bits=64, commit=00000000, modified=0, pid=22528, just started
22528:C 23 Jul 2019 10:00:13.732 # Configuration loaded

9.redis开机启动
拷贝 redis 安装目前下的 /root/redis-5.0.5/utils/redis_init_script 到 /etc/init.d/redis文件中；

cp /root/redis-5.0.5/utils/redis_init_script /etc/init.d/redis

编辑/etc/init.d/redis文件

[[e-mail]_0_16_centos init.d]# vim redis 
	CONF="/etc/redis/redis.conf"(这路径是第八步的复制后的路径)
[[e-mail]_0_16_centos init.d]# chkconfig --add redis（这一步好像不用也可以）
[[e-mail]_0_16_centos init.d]# chkconfig redis on 
[[e-mail]_0_16_centos init.d]# service redis stop
Stopping ...
Redis stopped
[[e-mail]_0_16_centos init.d]# service redis start
Starting Redis server...

10.连接RedisDesktopManager

[[e-mail]_0_16_centos ~]# vim /etc/redis/redis.conf

编辑Redis的配置文件，我这里是第八步自己创建的文件

记得重启redis
