01.Redis3.2.6 安装及分布式配置 参考redis3.0.3 安装与配置
1、安装 ####1.1 mac 上安装redis
1）官网 https://redis.io/ 下载最新的稳定版本，我下的是3.2.6
2）sudo tar -zxf redis-3.2.6.zip 解压文件
3）进入解压后的目录 cd redis－3.2.6
sudo make test 测试编译
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 21 seconds - integration/convert-zipmap-hash-on-load 85 seconds - unit/dump 8 seconds - unit/limits 14 seconds - unit/introspection-2 78 seconds - integration/replication-2 93 seconds - unit/sort 14 seconds - unit/bitfield 100 seconds - unit/type/list-3 41 seconds - unit/maxmemory 43 seconds - unit/bitops 56 seconds - unit/scripting 128 seconds - unit/type/list-2 43 seconds - unit/memefficiency 135 seconds - integration/replication 79 seconds - unit/obuf-limits 148 seconds - integration/replication-3 75 seconds - unit/hyperloglog 162 seconds - integration/replication-4 104 seconds - unit/geo 182 seconds - integration/replication-psync \o/ All tests passed without errors! Cleanup: may take some time... OK
5)、sudo make install
1 2 3 4 5 6 7 8 9 10 11 localhost:redis-3.2.6 xingzhe$ sudo make install Password: cd src && /Applications/Xcode.app/Contents/Developer/usr/bin/make install Hint: It's a good idea to run 'make test' ;) INSTALL install INSTALL install INSTALL install INSTALL install INSTALL install
至此，你已成功安装redis！
####1.2 centos7 上安装redis
1)、安装前，升级系统
1 wget http://download.redis.io/releases/redis-3.2.6.tar.gz
3)、解压
1 tar -xvf redis-3.2.6.tar.gz redis-3.2.6
4)、进入解压后的目录
5)、运行runtest
1 2 # ./runtest You need tcl 8.5 or newer in order to run the Redis test
如果提示 需要安装tcl，执行6步，否则跳过。
7)、编译
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 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 # make cd src && make all make[1]: 进入目录“/tdata/redis-3.2.6/src” rm -rf redis-server redis-sentinel redis-cli redis-benchmark redis-check-rdb redis-check-aof *.o *.gcda *.gcno *.gcov redis.info lcov-html (cd ../deps && make distclean) make[2]: 进入目录“/tdata/redis-3.2.6/deps” (cd hiredis && make clean) > /dev/null || true (cd linenoise && make clean) > /dev/null || true (cd lua && make clean) > /dev/null || true (cd geohash-int && make clean) > /dev/null || true (cd jemalloc && [ -f Makefile ] && make distclean) > /dev/null || true (rm -f .make-*) make[2]: 离开目录“/tdata/redis-3.2.6/deps” (rm -f .make-*) echo STD=-std=c99 -pedantic -DREDIS_STATIC='' >> .make-settings echo WARN=-Wall -W >> .make-settings echo OPT=-O2 >> .make-settings echo MALLOC=jemalloc >> .make-settings echo CFLAGS= >> .make-settings echo LDFLAGS= >> .make-settings echo REDIS_CFLAGS= >> .make-settings echo REDIS_LDFLAGS= >> .make-settings echo PREV_FINAL_CFLAGS=-std=c99 -pedantic -DREDIS_STATIC='' -Wall -W -O2 -g -ggdb -I../deps/geohash-int -I../deps/hiredis -I../deps/linenoise -I../deps/lua/src -DUSE_JEMALLOC -I../deps/jemalloc/include >> .make-settings echo PREV_FINAL_LDFLAGS= -g -ggdb -rdynamic >> .make-settings (cd ../deps && make hiredis linenoise lua geohash-int jemalloc) make[2]: 进入目录“/tdata/redis-3.2.6/deps” (cd hiredis && make clean) > /dev/null || true (cd linenoise && make clean) > /dev/null || true (cd lua && make clean) > /dev/null || true (cd geohash-int && make clean) > /dev/null || true (cd jemalloc && [ -f Makefile ] && make distclean) > /dev/null || true (rm -f .make-*) (echo "" > .make-cflags) (echo "" > .make-ldflags) MAKE hiredis cd hiredis && make static make[3]: 进入目录“/tdata/redis-3.2.6/deps/hiredis” gcc -std=c99 -pedantic -c -O3 -fPIC -Wall -W -Wstrict-prototypes -Wwrite-strings -g -ggdb net.c make[3]: gcc：命令未找到 make[3]: *** [net.o] 错误 127 make[3]: 离开目录“/tdata/redis-3.2.6/deps/hiredis” make[2]: *** [hiredis] 错误 2 make[2]: 离开目录“/tdata/redis-3.2.6/deps” make[1]: [persist-settings] 错误 2 (忽略) CC adlist.o /bin/sh: cc: 未找到命令 make[1]: *** [adlist.o] 错误 127 make[1]: 离开目录“/tdata/redis-3.2.6/src” make: *** [all] 错误 2
若出现上面错误，说明缺少编译环境，需要安装gcc。否则跳过8步。
1 2 3 4 5 6 7 8 9 10 11 12 cd src && make all make[1]: 进入目录“/tdata/redis-3.2.6/src” CC adlist.o In file included from adlist.c:34:0: zmalloc.h:50:31: 致命错误：jemalloc/jemalloc.h：没有那个文件或目录 #include <jemalloc/jemalloc.h> ^ 编译中断。 make[1]: *** [adlist.o] 错误 1 make[1]: 离开目录“/tdata/redis-3.2.6/src” make: *** [all] 错误 2
8)、安装gcc
安装成功转到6步，执行make命令。
10)、安装
注：在编译时，出现“../deps/geohash-int/geohash.h:78:18: 附注：‘longitude’在此声明” 警告；还有一个变量未定义。不清楚是否会有影响。目前，安装后运行测试都正常。
Redis Desktop Manager
验证 1)、启动服务
Redis 安装 启动 连接 配置 重启
2)、测试
1 2 3 4 5 $ redis-cli 127.0.0.1:6379> set foo bar OK 127.0.0.1:6379> get foo "bar"
恭喜你，已经成功安装！
2、分布式配置 参考[1]:Redis Cluster搭建方法简介
参考[2]: Centos7 搭建Redis3.2.0版本集群环境
准备ruby环境,后续redis-trib.rb会用到。
1 2 3 # yum install ruby # yum install rubygems # gem install redis
搭建并使用Redis集群[] 1、准备redis.conf配置文件
1 2 3 4 5 port 7000 cluster-enabled yes cluster-config-file nodes.conf cluster-node-timeout 5000 appendonly yes
2、创建目录后分别启动
1 2 3 mkdir cluster-test cd cluster-test mkdir 7000 7001 7002 7003 7004 7005
在文件夹 7000 至 7005 中， 各创建一个 redis.conf 文件,文件中的端口与文件加相同。
1 2 3 4 5 6 7 8 9 10 11 12 cd 7000/ ../redis-server ./redis.conf & cd ../7001 ../redis-server ./redis.conf & cd ../7002 ../redis-server ./redis.conf & cd ../7003 ../redis-server ./redis.conf & cd ../7004 ../redis-server ./redis.conf & cd ../7005 ../redis-server ./redis.conf &
nohup redis-server ./redis.conf > /cluster-test/log/redis-7000.log 2>&1 &
chomd +X runcluster.sh //添加执行权限
3、搭建集群
1 ./redis-trib.rb create --replicas 1 127.0.0.1:7000 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005
注意:在执行时会出现”All nodes agree about slots configuration”提示,不能直接回车,一定输入yes再回车。
1 2 3 4 12400:S 12 Jan 14:45:21.671 * Background AOF rewrite finished successfully 12397:M 12 Jan 14:45:22.055 # Cluster state changed: ok 12398:M 12 Jan 14:45:22.155 # Cluster state changed: ok 12399:M 12 Jan 14:45:22.189 # Cluster state changed: ok
4、检验是否配置成功
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 27 28 redis-cli -c -p 7000 127.0.0.1:7000> cluster nodes 1577e1769a77367dd4a626b316f4191224f726c6 127.0.0.1:7005 slave 8da8517b0edd30f30104e091d782d40803c0723d 0 1484203764628 6 connected 7436728328935447bccc1c1b54e6eab372b8c4e1 127.0.0.1:7000 myself,master - 0 0 1 connected 0-5460 8da8517b0edd30f30104e091d782d40803c0723d 127.0.0.1:7002 master - 0 1484203766133 3 connected 10923-16383 3a3e3c8407ee19f9f762c3a7496fc0d213ee452d 127.0.0.1:7001 master - 0 1484203765631 2 connected 5461-10922 48302b26e73b33da61914a33d62865ba0e83f6cb 127.0.0.1:7003 slave 7436728328935447bccc1c1b54e6eab372b8c4e1 0 1484203764127 4 connected 5b75f1ce4b70e3a780016d3a77daea7adde432ce 127.0.0.1:7004 slave 3a3e3c8407ee19f9f762c3a7496fc0d213ee452d 0 1484203765129 5 connected 127.0.0.1:7000> cluster info cluster_state:ok cluster_slots_assigned:16384 cluster_slots_ok:16384 cluster_slots_pfail:0 cluster_slots_fail:0 cluster_known_nodes:6 cluster_size:3 cluster_current_epoch:6 cluster_my_epoch:1 cluster_stats_messages_sent:1169 cluster_stats_messages_received:1169 127.0.0.1:7000> set name hello -> Redirected to slot [5798] located at 127.0.0.1:7001 OK redis-cli -c -p 7003 127.0.0.1:7003> get name -> Redirected to slot [5798] located at 127.0.0.1:7001 "hello"
5、 redis集群设置密码
1 2 3 config set masterauth abc config set requirepass abc config rewrite
config set masterauth “simonzhang”
密码方式访问：
redis-cli -p 7000 -a abc //abc is password
1 2 3 4 5 6 #客户端关闭 redis-cli -h 127.0.0.1 -p 6379 shutdown redis-cli -h 127.0.0.1 -p 6380 shutdown #启动 redis-server redis6379.conf & redis-server redis6380.conf &
??? 主从切换
3、搭建前哨sentinel 配置
注：sentinel.conf中要指定redis服务器的网络ip地址.不能为本机地址（127.0.0.1/localhost）。这是在单机部署时一定要注意的。
在有sentinel的集群环境中报：
1 2 3 4 5 6 DENIED Redis is running in protected mode because protected mode is enabled, no bind address was specified, no authentication password is requested to clients. In this mode connections are only accepted from the loopback interface. If you want to connect from external computers to Redis you may adopt one of the following solutions: 1) Just disable protected mode sending the command 'CONFIG SET protected-mode no' from the loopback interface by connecting to Redis from the same host the server is running, however MAKE SURE Redis is not publicly accessible from internet if you do so. Use CONFIG REWRITE to make this change permanent. 2) Alternatively you can just disable the protected mode by editing the Redis configuration file, and setting the protected mode option to 'no', and then restarting the server. 3) If you started the server manually just for testing, restart it with the '--protected-mode no' option. 4) Setup a bind address or an authentication password. NOTE: You only need to do one of the above things in order for the server to start accepting connections from the outside.
4、主从配置 master 部署在192.168.0.99上，配置文件为redis.conf;slave部署在192.168.0.100上，从master上复制一份配置文件命名为redis-slave.conf,如果你是单机部署需要修改ip和端口号。
1 slaveof 192.168.0.99 6379
