CentOS系統redis主從模式實現

安裝配置

# 安裝yum install epel-release （centos 7可以直接安裝epel源）yum install redis# 配置vi /etc/redis.confvi /etc/redis-sentinel.conf# 啟動redis-server /etc/redis.confredis-sentinel /etc/redis-sentinel.conf

redis.conf常用設定

# bind 127.0.0.1protected-mode noport 6379daemonize yesmaxclients 10000requirepass <password>appendonly yes# slaveof及masterauth僅在從節點設定slaveof <masterip> <masterport>masterauth <master-password>

redis-sentinel.conf常用設定

protected-mode nodaemonize yesport 26397sentinel monitor <master-name> <ip> <redis-port> <quorum>sentinel auth-pass <master-name> <password>

開機自啟

# 編輯vi /etc/init.d/redisd# 賦權chmod 755 /etc/init.d/redisd# 嘗試/etc/init.d/redisd startservice redisd start/stop/restart# 自啟chkconfig redisd on
