redis单节点简单安装 #115

Open Zakariyya opened 4 years ago

Zakariyya commented 4 years ago

安装编译依赖

# centos
yum install gcc
yum -y install tcl*

# ubuntu
apt-get install build-essential tcl

下载redis

curl -o ./redis-2.8.24.tar.gz http://download.redis.io/releases/redis-2.8.24.tar.gz

编译安装

make
make test

出现报错：You need tcl 8.5 or newer in order to run the Redis test 正解:apt-get update 如果已update 请执行下列逻辑 解决方式:安装 tcl

wget http://downloads.sourceforge.net/tcl/tcl8.6.1-src.tar.gz  
sudo tar xzvf tcl8.6.1-src.tar.gz  -C /usr/local/  
cd  /usr/local/tcl8.6.1/unix/  
sudo ./configure  
sudo make  
sudo make install
make install

配置

mkdir /etc/redis/
cd /etc/redis
sudo cp /data/redis/redis-2.8.24/redis.conf ./redis.conf

启动（&后台启动）

redis-server /etc/redis/redis.conf &

关闭

redis-cli shutdown

哨兵模式

在redis单节点安装前3步的基础上，以三台Centeos 7(因为在openstack内，所以10.36.8段的是浮动ip)为例：

|||||| |10.36.8.3| redis1 | sentinel1 |#主 |内部ip:192.168.0.9 | |10.36.8.4| redis2 | sentinel2 |#从 |内部ip:192.168.0.10 | |10.36.8.7| | sentinel3 |# |内部ip:192.168.0.11|

配置redis.conf

创建配置文件

sudo mkdir /etc/redis/
cd /etc/redis
sudo cp /data/redis/redis-2.8.24/redis.conf ./redis.conf

修改redis.conf（只配置主从两台，主从配置不同）

vim ./redis.conf

#10.36.8.3   redis1  sentinel1   #主 内部ip:192.168.0.9
bind 192.168.0.9
requirepass hostsname

#10.36.8.4   redis2  sentinel2   #从 内部ip:192.168.0.10
bind 192.168.0.10
slaveof 192.168.0.9 6379
masterauth hostsname
requirepass hostsname

修改sentinel.conf

创建配置文件：

cd /etc/redis
sudo cp /data/redis/redis-2.8.24/sentinel.conf ./sentinel.conf

修改sentinel.conf（三台配置相同）

||||| |sentinel| monitor |mymaster| 192.168.0.9 6379 2 | |sentinel| auth-pass |mymaster| hostsname |

主从启动&测试

启动

# 192.168.0.9
redis-server /etc/redis/redis.conf  &

# 192.168.0.10
redis-server /etc/redis/redis.conf

可以看到控制台中有打印主从建立联系，命令后加&可后台启动

测试 (在主节点写入，从节点可看到)

# 192.168.0.9
$ redis-cli -a hostsname -h 192.168.0.9  -p 6379
192.168.0.9:6379> set a 1
OK
192.168.0.9:6379> get a
"1"
192.168.0.9:6379> 

# 192.168.0.10
$ redis-cli -a hostsname -h 192.168.0.10 -p 6379
192.168.0.10:6379> keys *
1) "a"
192.168.0.10:6379> get a
"1"
192.168.0.10:6379>

哨兵启动&测试

启动

redis-sentinel /etc/redis/sentinel.conf &

测试

在任意一台,查询主节点

$ redis-cli -a hostsname -h 192.168.0.10 -p 26379
192.168.0.10:26379> SENTINEL get-master-addr-by-name mymaster
1) "192.168.0.9"
2) "6379"
192.168.0.10:26379>
