一、redis主从搭建
1、搭建redis master
1>redis安装
mkdir -p /usr/local/webserver/redis //安装目录 cd /usr/local/webserver/redis wget http://download.redis.io/redis-stable.tar.gz //最新稳定版 tar xzf redis-stable.tar.gz cd redis-stable make //报错的话 install gcc make install //redis可执行文件redis-cli,redis-server等会被复制到/usr/local/bin,命令行直接输入即可执行
2>主配置文件redis_master.conf做如下修改:
daemonize yes //使redis能以守护进程模式运行 pidfile /var/run/redis_6379.pid //设置redis PID 文件位置 port 6379 dir /var/redis/6379 //设置持久化文件存放位置
3>启动master
[[email protected] redis-stable]# redis-server redis_master.conf [[email protected]-sentinel redis-stable]# ps -ef|grep redis root 5504 1 0 12:41 ? 00:00:00 redis-server 127.0.0.1:6379 root 5508 1361 0 12:41 pts/0 00:00:00 grep redis
4>使用客户端连接测试
[[email protected] redis-stable]# redis-cli -p 6379 127.0.0.1:6379> set ww 1 OK 127.0.0.1:6379> get ww "1"
2、搭建2个redis slave
1>从配置文件redis_slave_6380.conf,redis_slave_6381.conf做如下修改:
daemonize yes //使redis能以守护进程模式运行 pidfile /var/run/redis_6380.pid //设置redis PID 文件位置 port 6380 dir /var/redis/6380 //设置持久化文件存放位置 slaveof 127.0.0.1 6379 //设置属于哪个master
daemonize yes //使redis能以守护进程模式运行 pidfile /var/run/redis_6381.pid //设置redis PID 文件位置 port 6381 dir /var/redis/6381 //设置持久化文件存放位置 slaveof 127.0.0.1 6379 //设置属于哪个master
2>启动slave并测试数据是否同步
[[email protected] redis-stable]# redis-server redis_slave_6380.conf [[email protected]-sentinel redis-stable]# ps -ef|grep redis root 5504 1 0 12:41 ? 00:00:02 redis-server 127.0.0.1:6379 root 5555 1 0 14:47 ? 00:00:00 redis-server 127.0.0.1:6380 root 5561 1361 0 14:48 pts/0 00:00:00 grep redis [[email protected]-sentinel redis-stable]# redis-cli -p 6380 127.0.0.1:6380> get ww "1" //数据已经同步过来
[[email protected] redis-stable]# redis-server redis_slave_6381.conf [[email protected]-sentinel redis-stable]# ps -ef|grep redis root 5504 1 0 12:41 ? 00:00:02 redis-server 127.0.0.1:6379 root 5555 1 0 14:47 ? 00:00:00 redis-server 127.0.0.1:6380 root 5557 1 0 14:48 ? 00:00:00 redis-server 127.0.0.1:6381 root 5561 1361 0 14:48 pts/0 00:00:00 grep redis [[email protected]-sentinel redis-stable]# redis-cli -p 6381 127.0.0.1:6380> get ww "1" //数据已经同步过来
二、Redis容灾部署(哨兵Sentinel)
1、三个哨兵文件配置
////sentinel_26379.conf port 26379 daemonize yes sentinel monitor mymaster 127.0.0.1 6379 2 sentinel myid 1c805b9134364d69986f9042c22e95debf1932c9 //sentinel_26380.conf port 26380 daemonize yes sentinel monitor mymaster 127.0.0.1 6379 2 sentinel myid ac1ef015411583d4b9f3d81cee830060b2f29862 //sentinel_26381.conf port 26381 daemonize yes sentinel monitor mymaster 127.0.0.1 6379 2 sentinel myid 0aca3a57038e2907c8a07be2b3c0d15171e44da5
2、启动sentinel,并查看sentinel所监控的master和slave
[[email protected] redis-stable]# redis-sentinel sentinel_26379.conf [[email protected]-sentinel redis-stable]# redis-sentinel sentinel_26380.conf [[email protected]-sentinel redis-stable]# redis-sentinel sentinel_26381.conf [[email protected]-sentinel redis-stable]# ps -ef|grep redis root 5504 1 0 12:41 ? 00:00:03 redis-server 127.0.0.1:6379 root 5555 1 0 14:47 ? 00:00:00 redis-server 127.0.0.1:6380 root 5606 1 0 15:23 ? 00:00:00 redis-server 127.0.0.1:6381 root 5770 1361 0 15:54 pts/0 00:00:00 redis-sentinel *:26379 [sentinel] root 5773 5429 0 15:54 pts/1 00:00:00 redis-sentinel *:26380 [sentinel] root 5776 5710 0 15:55 pts/2 00:00:00 redis-sentinel *:26381 [sentinel] root 5781 5743 0 15:57 pts/3 00:00:00 grep redis [[email protected]-sentinel redis-stable]# redis-cli -p 26379 127.0.0.1:26379> sentinel masters 1) 1) "name" 2) "mymaster" 3) "ip" 4) "127.0.0.1" 5) "port" 6) "6379" 7) "runid" 8) "83491622b984fa6bbb4cd7761c77b23491569b1b" 9) "flags" 10) "master" ... 127.0.0.1:26379> SENTINEL slaves mymaster 1) 1) "name" 2) "127.0.0.1:6380" 3) "ip" 4) "127.0.0.1" 5) "port" 6) "6380" 7) "runid" 8) "e532cc9e510bf93a6c3dd5d978be8364c91c616f" 9) "flags" 10) "slave" ... 2) 1) "name" 2) "127.0.0.1:6381" 3) "ip" 4) "127.0.0.1" 5) "port" 6) "6381" 7) "runid" 8) "f7cee9c9f6e5a346d38f2a09dfc9eb4846118ae5" 9) "flags" 10) "slave" ... 127.0.0.1:26379> SENTINEL get-master-addr-by-name mymaster 1) "127.0.0.1" 2) "6379" [[email protected]-sentinel redis-stable]# kill -9 5504 [[email protected]-sentinel redis-stable]# ps -ef|grep redis root 5555 1 0 14:47 ? 00:00:00 redis-server 127.0.0.1:6380 root 5606 1 0 15:23 ? 00:00:00 redis-server 127.0.0.1:6381 root 5770 1361 0 15:54 pts/0 00:00:00 redis-sentinel *:26379 [sentinel] root 5773 5429 0 15:54 pts/1 00:00:00 redis-sentinel *:26380 [sentinel] root 5776 5710 0 15:55 pts/2 00:00:00 redis-sentinel *:26381 [sentinel] root 5789 5743 0 15:59 pts/3 00:00:00 grep redis //主库出现故障时自动将从库转换为主库 [[email protected]-sentinel redis-stable]# redis-cli -p 26379 127.0.0.1:26379> SENTINEL get-master-addr-by-name mymaster 1) "127.0.0.1" 2) "6380"
三、jedis中使用哨兵,具体代码参考haixuanweb
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"> <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig"> <property name="maxTotal" value="1000"/> <property name="maxIdle" value="10"/> <property name="minIdle" value="1"/> <property name="maxWaitMillis" value="30000"/> <property name="testOnBorrow" value="true"/> <property name="testOnReturn" value="true"/> <property name="testWhileIdle" value="true"/> </bean> <bean id="cacheService" class="sentinel.CacheServiceImpl" destroy-method="destroy"> <property name="jedisSentinlePool"> <bean class="redis.clients.jedis.JedisSentinelPool"> <constructor-arg index="0" value="mymaster" /> <constructor-arg index="1"> <set> <value>192.168.13.128:26379</value> <value>192.168.13.128:26380</value> <value>192.168.13.128:26381</value> </set> </constructor-arg> <constructor-arg index="2" ref="jedisPoolConfig" /> </bean> </property> </bean> </beans>
public class CacheServiceImpl implements CacheService { private static Logger logger = LoggerFactory.getLogger(CacheServiceImpl.class); private JedisSentinelPool jedisSentinlePool; public void set(String key, String value) { JedisSentinelPool pool = getJedisSentinelPool(); Jedis jedis = pool.getResource(); try { jedis.set(key, value); } catch (Exception e) { pool.returnBrokenResource(jedis); }finally { if(pool!=null){ pool.returnResource(jedis); } } } }
public interface CacheService { public void set(String key, String value); }
@Controller public class GoodsController extends BaseNoLoginController { @Autowired private CacheService cacheService; ... }
