golang工程——中间件redis，单节点集群部署

单节点redis集群部署

部署redis 6.2.7版本

没资源，就用一台机子部

解压安装包

tar zxf redis-6.2.7.tar.gz

cd redis-6.2.7

编译安装

mkdir -p /var/local/redis-6.2.7/{data,conf,logs,pid}

data：数据目录
conf：配置文件目录
logs：日志目录
pid：redis进程文件目录

make

make install PREFIX=/var/local/redis-6.2.7

拷贝配置

cp redis.conf /var/local/redis-6.2.7/conf/redis_7001.conf
cd /var/local/redis-6.2.7

修改配置

logfile可以不加，这样日志会输出到/dev/null，不用怕文件过大有写入错误

bind 0.0.0.0
port 7001 # 修改默认端口，只要不占用就可以
daemonize yes # 后台运行程序
pidfile /var/local/redis-6.2.7/pid/redis_7001.pid # 以端口命名pid文件名
loglevel notice
logfile "/var/local/redis-6.2.7/logs/redis_7001.log" # 以端口命名log文件名
dbfilename dump_7001.rdb
dir /var/local/redis-6.2.7/data
repl-disable-tcp-nodelay yes
requirepass  xxxwoaixuexi.. # 这是密码
maxclients 10000
maxmemory 524288000 # 500M
maxmemory-policy allkeys-lru
appendonly yes
appendfilename "appendonly_7001.aof"
no-appendfsync-on-rewrite yes
auto-aof-rewrite-percentage 100
cluster-enabled yes
cluster-config-file nodes_7001.conf
cluster-node-timeout 15000
cluster-migration-barrier 1

拷贝五份配置（至少要六个节点组集群）

cp conf/redis_7001.conf conf/redis_7002.conf

cp conf/redis_7001.conf conf/redis_7003.conf

cp conf/redis_7001.conf conf/redis_7004.conf

cp conf/redis_7001.conf conf/redis_7005.conf

cp conf/redis_7001.conf conf/redis_7006.conf

替换端口

sed -i 's/7001/7002/g' conf/redis_7002.conf

sed -i 's/7001/7003/g' conf/redis_7003.conf

sed -i 's/7001/7004/g' conf/redis_7004.conf

sed -i 's/7001/7005/g' conf/redis_7005.conf

sed -i 's/7001/7006/g' conf/redis_7006.conf

启动脚本 start_redis.sh

REDIS_HOME=/var/local/redis-6.2.7
$REDIS_HOME/bin/redis-server $REDIS_HOME/conf/redis_7001.conf &
sleep 1s
$REDIS_HOME/bin/redis-server $REDIS_HOME/conf/redis_7002.conf &
sleep 1s
$REDIS_HOME/bin/redis-server $REDIS_HOME/conf/redis_7003.conf &
sleep 1s
$REDIS_HOME/bin/redis-server $REDIS_HOME/conf/redis_7004.conf &
sleep 1s
$REDIS_HOME/bin/redis-server $REDIS_HOME/conf/redis_7005.conf &
sleep 1s
$REDIS_HOME/bin/redis-server $REDIS_HOME/conf/redis_7006.conf &

配置集群

bin/redis-cli -a xxxwoaixuexi.. --cluster create --cluster-replicas 1 10.65.132.113:7001 10.65.132.113:7002 10.65.132.113:7003 10.65.132.113:7004 10.65.132.113:7005 10.65.132.113:7006
