Redis安装及主从设置

   Redis安装及主从设置
一 准备

服务器需要安装  gcc

yum install gcc -y

安装用户为root
二安装

2.1安装主服务器并测试
 
1.放置在opt目录下
cd /opt
tar –zxvf tar -zxvf redis-3.0.4.tar.gz
2.更改目录名
mv redis-3.0.4 redis
3.进入src目录编译安装
cd redis/src
make
make install

4.为了方便管理，将脚本文件和配置文件移动到/usr/local/redis目录下
创建目录/usr/local/redis/bin   /usr/local/redis/etc
将opt/redis/src下的可执行命令全部移动到/usr/local/redis/bin/目录下，执行该命令：
移动安装文件
mv mkreleasehdr.sh redis-benchmark redis-check-aof redis-check-dump redis-cli redis-sentinel redis-server /usr/local/redis/bin
移动配置文件
mv redis.conf /usr/local/redis/etc



5.修改配置文件 redis.conf
注意修改的地方：
主服务器设置【192.168.20.38】
# vim /usr/local/redis/etc/redis.conf
daemonize yes
pidfile /usr/local/redis/var/redis.pid
port 6379
bind 192.168.20.38
unixsocket /usr/local/redis/var/redis.sock
unixsocketperm 755
timeout 300
loglevel verbose
logfile /data/logs/redis/redis.log
# syslog-enabled no
# syslog-ident redis
# syslog-facility local0
databases 16
save 900 1
save 300 10
save 60 10000
rdbcompression yes
dbfilename dump.rdb
dir /data/dbcache
# slaveof <masterip> <masterport>
# masterauth <master-password>
# repl-ping-slave-period 10
# repl-timeout 60
requirepass redis123
# rename-command CONFIG ""
maxclients 0
# maxmemory <bytes>
# maxmemory-policy volatile-lru
# maxmemory-samples 3
appendonly no
appendfilename appendonly.aof
appendfsync always
no-appendfsync-on-rewrite no
auto-aof-rewrite-percentage 100
auto-aof-rewrite-min-size 64mb
slowlog-log-slower-than 10000
slowlog-max-len 128
vm-enabled no
vm-swap-file /data/dbcache/redis.swap
vm-max-memory 0
vm-page-size 32
vm-pages 134217728
vm-max-threads 4
glueoutputbuf yes
hash-max-zipmap-entries 512
hash-max-zipmap-value 64
list-max-ziplist-entries 512
list-max-ziplist-value 64
set-max-intset-entries 512
zset-max-ziplist-entries 128
zset-max-ziplist-value 64
activerehashing yes

6.启动redis
进入/usr/local/redis/bin/目录下开启Redis服务。
/usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf
注意：开启redis服务需要指定配置文件，如不指定配置文件则加载默认配置文件。

7.客户端登录
/usr/local/redis/bin/redis-cli -h 192.168.20.38 -a redis123

8.停止服务
/usr/local/redis/bin/redis-cli -h 192.168.20.38 -a redis123  shutdown

2.2安装从服务器并测试
1.从服务器redis服务的安装
     安装步骤同上，其配置文件略有不同。

从服务器设置【192.168.20.41】
daemonize yes
pidfile /usr/local/redis/var/redis.pid
port 6379
bind 192.168.20.41
unixsocket /usr/local/redis/var/redis.sock
unixsocketperm 755
timeout 300
loglevel verbose
logfile /data/logs/redis/redis.log
# syslog-enabled no
# syslog-ident redis
# syslog-facility local0
databases 16
save 900 1
save 300 10
save 60 10000
rdbcompression yes
dbfilename dump.rdb
dir /data/dbcache
# slaveof <masterip> <masterport>
# masterauth <master-password>
# repl-ping-slave-period 10
# repl-timeout 60
# rename-command CONFIG ""

# maxmemory <bytes>
# maxmemory-policy volatile-lru
# maxmemory-samples 3
appendonly no
appendfilename appendonly.aof
appendfsync always
no-appendfsync-on-rewrite no
auto-aof-rewrite-percentage 100

list-max-ziplist-entries 512
list-max-ziplist-value 64

2. 启动服务
/usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf

3.客户端测试
/usr/local/redis/bin/redis-cli -h 192.168.20.41

4.验证主从
主服务器上执行：
/usr/local/redis/bin/redis-cli -h 192.168.20.38 -a redis123 set test 123456
从服务器上执行，查看结果：
/usr/local/redis/bin/redis-cli -h 192.168.20.41 get test

5.停止服务
/usr/local/redis/bin/redis-cli -h 192.168.20.41 shutdown
