实验环境:
系统:CentOS7
软件:redis-5.0.2
一、解压redis-5.0.2
三个节点
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | [root@red1 software] # cd /usr/local/ [root@red1 local ] # ll total 1912 drwxr-xr-x. 2 root root 134 Apr 10 21:45 bin drwxr-xr-x. 2 root root 6 Apr 11 2018 etc drwxr-xr-x. 2 root root 6 Apr 11 2018 games drwxr-xr-x. 2 root root 6 Apr 11 2018 include drwxr-xr-x. 2 root root 6 Apr 11 2018 lib drwxr-xr-x. 2 root root 6 Apr 11 2018 lib64 drwxr-xr-x. 2 root root 6 Apr 11 2018 libexec drwxrwxr-x. 6 root root 4096 Apr 11 11:49 redis -rw-r--r--. 1 root root 1952989 Apr 10 21:42 redis-5.0.2. tar .gz drwxr-xr-x. 2 root root 6 Apr 11 2018 sbin drwxr-xr-x. 5 root root 49 Oct 22 10:25 share drwxr-xr-x. 2 root root 6 Apr 11 2018 src |
二、安装 Redis
三个节点
make
make install
三、修改环境变量
三个节点
安装完 Redis之后,在/usr/local/bin会生成一些脚本
1 2 3 4 5 6 7 8 9 | [root@red1 local ] # cd /usr/local/bin/ [root@red1 bin] # ll total 32628 -rwxr-xr-x. 1 root root 4365456 Apr 10 21:45 redis-benchmark -rwxr-xr-x. 1 root root 8084864 Apr 10 21:45 redis-check-aof -rwxr-xr-x. 1 root root 8084864 Apr 10 21:45 redis-check-rdb -rwxr-xr-x. 1 root root 4786592 Apr 10 21:45 redis-cli lrwxrwxrwx. 1 root root 12 Apr 10 21:45 redis-sentinel -> redis-server -rwxr-xr-x. 1 root root 8084864 Apr 10 21:45 redis-server |
修改环境变量
1 | PATH=\$PATH: /mysql/app/mysql/bin : /mysql/app/xtrabackup/bin :$HOME /bin : /usr/bin : /sbin : /bin : /usr/local/bin |
1 | source .bash_profile |
四、配置 Redis配置文件
主节点192.168.8.11
1 2 3 4 | port 6000 #端口号 requirepass 123456 #登录口令 bind 192.168.8.11 #绑定IP daemonize yes #后台运行redis |
从节点一
1 2 3 4 5 6 7 | port 6001 #端口号 bind 192.168.8.12 #绑定IP slaveof 192.168.8.11 6000 #设置主节点信息 masterauth 123456 #主节点口令 requirepass 123456 #登录口令 slave- read -only yes #只读模式 daemonize yes #后台运行redis |
从节点二
1 2 3 4 5 6 7 | port 6002 #端口号 bind 192.168.8.13 #绑定IP slaveof 192.168.8.11 6000 #设置主节点信息 masterauth 123456 #主节点口令 requirepass 123456 #登录口令 slave- read -only yes #只读模式 daemonize yes #后台运行redis |
五、启动Redis
先启动主节点,在启动从节点
主节点
1 2 3 4 5 6 | [root@red1 redis] # redis-server /usr/local/redis/redis.conf [root@red1 redis] # [root@red1 redis] # [root@red1 redis] # ps -ef|grep redis root 2012 1 0 21:35 ? 00:00:00 redis-server 192.168.8.11:6000 root 2017 1384 0 21:35 pts /0 00:00:00 grep --color=auto redis |
可以看到端口号为6000的redis服务已经启动
从节点一
1 2 3 4 | root@red2 ~] # redis-server /usr/local/redis/redis.conf [root@red2 ~] # ps -ef|grep redis root 1968 1 0 21:36 ? 00:00:00 redis-server 192.168.8.12:6001 root 1973 1386 0 21:36 pts /0 00:00:00 grep --color=auto redis |
可以看到端口号为6001的 redis服务已经启动
从节点二
1 2 3 | [root@red3 ~] # ps -ef|grep redis root 1943 1 0 21:36 ? 00:00:00 redis-server 192.168.8.13:6002 root 1956 1034 0 21:36 pts /0 00:00:00 grep --color=auto redis |
可以看到端口号为6002的 redis服务已经启动
六、可用性验证
主节点
1 2 3 4 5 6 7 8 9 10 | [root@red1 redis] # redis-cli -p 6000 -a 123456 -h 192.168.8.11 Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe. 192.168.8.11:6000> get 1 "hello" 192.168.8.11:6000> get 3 (nil) 192.168.8.11:6000> set 3 world OK 192.168.8.11:6000> get 3 "world" |
从节点一
1 2 3 4 | [root@red2 ~] # redis-cli -p 6001 -a 123456 -h 192.168.8.12 Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe. 192.168.8.12:6001> get 3 "world" |
从节点二
1 2 3 4 | [root@red3 ~] # redis-cli -p 6002 -h 192.168.8.13 -a 123456 Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe. 192.168.8.13:6002> get 3 "world" |
