| 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
1 | yum -y install gcc gcc-c++ |
二、安装Redis
1、下载安装包
1 | wget http://download.redis.io/releases/redis-7.2.5.tar.gz |
2、解压
1 | tar -zxvf redis-7.2.5.tar.gz -C /opt/ |
3、创建工作目录
1 2 | mkdir -p /opt/redis/mkdir -p /opt/redis/logs/ |
4、编译安装
1 2 3 4 5 6 7 8 | # 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）
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | 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 final123 |
6、修改配置文件（Slave）
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | 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 final123replilcaof 192.168.140.153 6379 |
7、创建启动脚本
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | [root@localhost redis]# vi /etc/systemd/system/redis.service[Unit]Description=RedisAfter=network.target [Service]Type=simpleUser=rootGroup=rootExecStart=/opt/redis/bin/redis-server /opt/redis/redis.conf --daemonize noRestart=alwaysLimitNPROC=65535LimitNOFILE=65535 [Install]WantedBy=multi-user.target |
8、启动服务
1 2 3 | systemctl daemon-reloadsystemctl start redis.servicesystemctl enable redis.service |
三、测试
1、配置环境变量
1 2 3 4 5 | [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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | [root@localhost redis]# redis-cli -h 192.168.140.153192.168.140.153:6379> auth final123OK192.168.140.153:6379> info replication# Replicationrole:masterconnected_slaves:1slave0:ip=192.168.140.159,port=6379,state=online,offset=350,lag=1master_failover_state:no-failovermaster_replid:28a3b660f11504c07b2cc4bc07a093970af1544bmaster_replid2:0000000000000000000000000000000000000000master_repl_offset:350second_repl_offset:-1repl_backlog_active:1repl_backlog_size:1048576repl_backlog_first_byte_offset:1repl_backlog_histlen:350 |
3、查看redis-slave
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 | [root@localhost redis]# redis-cli -h 192.168.140.159192.168.140.159:6379> auth final123OK192.168.140.159:6379> info replication# Replicationrole:slavemaster_host:192.168.140.153master_port:6379master_link_status:upmaster_last_io_seconds_ago:6master_sync_in_progress:0slave_read_repl_offset:406slave_repl_offset:406slave_priority:100slave_read_only:1replica_announced:1connected_slaves:0master_failover_state:no-failovermaster_replid:28a3b660f11504c07b2cc4bc07a093970af1544bmaster_replid2:0000000000000000000000000000000000000000master_repl_offset:406second_repl_offset:-1repl_backlog_active:1repl_backlog_size:1048576repl_backlog_first_byte_offset:1repl_backlog_histlen:406 |
4、master节点插入数据
1 2 3 4 | 192.168.140.153:6379> set test "master"OK192.168.140.153:6379> get test"master" |
5、slave节点查看数据是否同步
1 2 3 4 5 | 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 replica. |
