Redis配置哨兵開機自啟動

• Redis哨兵

啟停命令

# 啟動3台redis
cd /opt/redis
./redis-server redis.conf

# 啟動3台sentinel
cd /opt/redis
./redis-sentinel sentinel.conf

測試sentinel模式

cd /opt/redis
./redis-cli -h master的ip

192.168.0.205:6379> auth 設置的密碼
192.168.0.205:6379> info

• 方案一
  腳本放到/etc/init.d/redisSentinel
  添加開機自啟動:

# 1.編輯rc.local文件
vi /etc/rc.local
# 2.添加redisSentinel 啟動命令
/etc/init.d/redisSentinel restart
# 3.最后修改rc.local文件的執行權限--一定要執行
chmod +x  /etc/rc.local
chmod 755 /etc/rc.local

vim /etc/init.d/redisSentinel
