**
下载安装文件
wget http://download.redis.io/releases/redis-3.2.8.tar.gztar -zxvf redis-3.2.8.tar.gz
cd redis-3.2.8
make
ls /usr/local/
cd src/
cd ../
cd utils/
cat INSTALL
make PREFIX=/usr/local/redis install
ls /usr/local/redis/bin/
mkdir /usr/local/redis/conf
cp redis.conf /usr/local/redis/conf/
cd utils/
cat install_server.sh
telnet
tree /usr/local/redis/
配置并启动redis服务
echo ‘PATH=/usr/local/redis/bin/:$PATH‘ >> /etc/profile
tail -1 /etc/profile
. /etc/profile
which redis-server
redis-server -h
启动:
redis-server /usr/local/redis/conf/redis.conf &
启动时出现警告：
26221:M 22 Mar 04:38:06.362 # WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.
26221:M 22 Mar 04:38:06.362 # Server started, Redis version 3.2.8
26221:M 22 Mar 04:38:06.365
echo ‘511‘ > /proc/sys/net/core/somaxconn
# WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add ‘vm.overcommit_memory = 1‘ to /etc/sysctl.conf and then reboot or run the command ‘sysctl vm.overcommit_memory=1‘ for this to take effect.
26221:M 22 Mar 04:38:06.365
# WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue run the command ‘echo never > /sys/kernel/mm/transparent_hugepage/enabled‘ as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.
26221:M 22 Mar 04:38:06.365 * The server is now ready to accept connections on port 6379
yum -y install lsof
lsof -i :6379
sysctl vm.overcommit_memory=1
vim /etc/sysctl.conf
最后一行加上:vm.overcommit_memory = 1
sysctl -p
关闭redis 服务
redis-cli shutdown save
用nc 命令在linux也可以操作redis:
echo ‘set name lisi‘ | nc 127.0.0.1 6379
设置密码:
配置文件：requirepass 123456
重启redis
redis-cli -a 135456 登录进去
或在redis-cli 命令行 auth 123456
配置文件可以改名或禁用危险命令:
rename-command 原命令 新命令
rename-command set ‘‘ 禁用所有命令
php 安装phpredis扩展
/usr/local/php7/bin/phpize
./configure --with-php-config=/usr/local/php7/bin/php-config
make && make install
提示扩展安装到了 /usr/local/php7/lib/php/extensions/no-debug-non-zts-20160303/
php.ini:
extension=/usr/local/php7/lib/php/extensions/no-debug-non-zts-20160303/redis.so
netstat -lntup |grep 6379
配置主从:
slave:
slaveof 192.168.1.199 6379 (支持域名)
masterauth 123456
slave-serve-stale-data yes
打开master
开启slave 就开始同步了
/****
在Docker容器中配置Redis主从关系是遇到slave redis节点启动时报
Error condition on socket for SYNC: Connection refused
解决方法
修改redis master节点配置文件
bind 0.0.0.0
重启服务
**/
slave : redis-cli命令行 : monitor 监控
slave 不能写数据
