IP | 操作系统 | 服务 | 版本 |
192.168.140.153 | Centos 7 | remaster | 7.2.5 |
192.168.140.159 | CentOS 7 | redis-slave | 7.2.5 |
一、安装依赖
yum -y install gcc gcc-c++
二、安装Redis
1、下载安装包
wget http://download.redis.io/releases/redis-7.2.5.tar.gz
2、解压
tar -zxvf redis-7.2.5.tar.gz -C /opt/
3、创建工作目录
mkdir -p /opt/redis/ mkdir -p /opt/redis/logs/
4、编译安装
# 进入解压目录 cd /opt/redis-7.2.5 # 编译 make # 安装 make install PREFIX=/opt/redis/
5、修改配置文件(Master)
cp /opt/redis-7.2.5/redis.conf /opt/redis/ vi /opt/redis/redis.conf # 修改如下内容 bind 192.168.140.153 -::1 # 允许后台运行 daemonize yes # pid文件位置 pidfile /opr/redis/redis_6379.pid # 日志位置 logfile "/opt/redis/logs/redis.log" # 工作目录 dir /opt/redis/ # 主从同步密码 masterauth final123 # redis密码 requirepass finaandroidl123
6、修改配置文件(Slave)
cp /opt/redis-7.2.5/redis.conf /opt/redis/ vi /opt/redis/redis.conf # 修改如下内容 bind 192.168.140.153 -::1 # 允许后台运行 daemonize yes # pid文件位置 pidfile /opr/redis/redis_6379.pid # 日志位置 logfile "/opt/redis/logs/redis.log" # 工作目录 dir /opt/redis/ # 主从同步密码 masterauth final123 # redis密码 requirepass fi编程nal123 replilcaof 192.168.140.153 6379
7、创建启动脚本
[root@localhost redis]# vi /etc/systemd/system/redis.service [Unit] Description=Redis After=network.target [Service] Type=simple User=root Group=root ExecStart=/opt/redis/bin/redis-server /opt/redis/redis.conf --daemonize no Restart=alwajsys LimitNPROC=65535 LimitNOFILE=65535 [Install] WantedBy=multi-user.target
8、启动服务
systemctl daemon-reload systemctl start redis.service systemctl enable redis.service
三、测试
1、配置环境变量
[root@localhost redis]# vi /etc/profile # 在最后添加如下内容 PATH=${PATH}:/opt/redis/bin/ [root@localhost redis]# source /etc/profile
2、查看redis-master
[root@localhost redis]# redis-cli -h 192.168.140.153 192.168.140.153:6379> auth final123 OK 192.168.140.153:6379> info replication # Replication role:master connected_slaves:1 slave0:ip=192.168.140.159,port=6379,state=online,offset=350,lag=1 master_failover_state:no-failover master_replid:28a3b660f11504c07b2cc4bc07a093970af1544b master_replid2:0000000000000000000000000000000000000000 master_repl_offset:350 second_repl_offset:-1 repl_backlog_active:1 repl_backlog_size:104编程客栈8576 repl_backlog_first_byte_offset:1 repl_backlog_histlen:350
3、查看redis-slave
[root@localhost redis]# redis-cli -h 192.168.140.159 192.168.140.159:6379> auth final123 OK 192.168.140.159:6379> info replication # Replication role:slave master_host:192.168.140.153 master_port:6379 master_link_status:up master_last_io_seconds_ago:6 master_sync_in_progress:0 slave_read_repl_offset:406 slave_repl_offset:406 slave_priority:100 slave_read_only:1 replica_announced:1 connected_slaves:0 master_failover_state:no-failover master_replid:28a3b660f11504c07b2cc4bc07a093970af1544b master_replid2:0000000000000000000000000000000000000000 master_repl_offset:406 second_repl_offset:-1 repl_backlog_active:1 repl_backlog_size:1048576 repl_backlog_first_byte_offset:1 repl_backlog_histlen:406
4、master节点插入数据
192.168.140.153:6379> set test "master" OK 192.168.140.153:6379> get test "master"
5、slave节点查看数据是否同步
192.168.140.159:6379> get test "master" # slave节点只能读取,不能写入。 192.168.140.159:6379> set test1 "ceshi" (error) READONLY You can't write against a read only replihttp://www.devze.comca.
