1、搭建一个 redis 哨兵集群
一主二从三哨兵模式
master(10.0.0.105)，slave1(10.0.0.106),slave2(10.0.0.107)
都执行以下脚本安装redis服务。
bash install_redis.sh #!/bin/bash . /etc/init.d/functions SRC_DIR=/usr/local/src REDIS='redis-5.0.9.tar.gz' VERSION=`echo $REDIS | sed -nr 's/^(.*).tar.*/1/p'` INSTALL_DIR=/apps/redis PASSWORD=123456 COLOR='echo -e E[01;31m' END='E[0m' ##检查 check(){ ##检查用户是否root if [ $UID -ne 0 ] ;then action "当前用户不是root，安装失败" false exit 1 fi cd $SRC_DIR ##检查nginx安装包是否存在 if [ ! -e $REDIS ] ;then $COLOR"缺少${REDIS}文件"$END $COLOR"请将相关文件放在${SRC_DIR}目录下"$END exit ##检查mysql是否已安装 elif [ -e ${INSTALL_DIR} ] ;then action "REDIS已存在，安装失败 " false exit else action "环境检测正常" return fi } ##安装redis install_redis(){ ##安装依赖包 yum install gcc jemalloc-devel -y > /dev/null [ $? -eq 0 ] && { action "依赖包安装" ;} || { action "依赖包安装" false ;exit ; } ##创建redis用户 id redis && action "创建Redis用户" || { useradd -r -s /sbin/nologin redis ; action "创建redis用户"; } ##创建apps文件夹 [ -d /apps ] || { mkdir /apps ; action "创建apps文件夹"; } cd $SRC_DIR tar xf $REDIS cd $VERSION make PREFIX=${INSTALL_DIR} install > /dev/null [ $? -eq 0 ] && action "make install " || { action "make install " false ; exit ;} mkdir ${INSTALL_DIR}/{etc,data,run,log} cp redis.conf ${INSTALL_DIR}/etc/ sed -ri 's/bind 127.0.0.1$/bind 0.0.0.0/' ${INSTALL_DIR}/etc/redis.conf sed -ri "/# requirepass .*/a requirepass ${PASSWORD}" ${INSTALL_DIR}/etc/redis.conf sed -ri "/^dir .*/c dir ${INSTALL_DIR}/data/" ${INSTALL_DIR}/etc/redis.conf sed -ri "/logfile .*/c logfile ${INSTALL_DIR}/log/redis_6379.log" ${INSTALL_DIR}/etc/redis.conf sed -ri "/daemonize .*/c daemonize yes" ${INSTALL_DIR}/etc/redis.conf sed -ri "/pidfile .*/c pidfile ${INSTALL_DIR}/run/redis_6379.pid" ${INSTALL_DIR}/etc/redis.conf echo "PATH=${INSTALL_DIR}/bin:$PATH" > /etc/profile.d/redis.sh . /etc/profile.d/redis.sh cat > /usr/lib/systemd/system/redis.service <<-EOF [Unit] Description=Redis persistent key-value database After=network.target [Service] ExecStart=${INSTALL_DIR}/bin/redis-server ${INSTALL_DIR}/etc/redis.conf --supervised systemd ExecStop=/bin/kill -s QUIT $MAINPID Type=notify User=redis Group=redis RuntimeDirectory=redis RuntimeDirectoryMode=0755 [Install] WantedBy=multi-user.target EOF cat >> /etc/sysctl.conf<<-EOF net.core.somaxconn = 1024 vm.overcommit_memory = 1 EOF sysctl -p echo 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' >> /etc/rc.d/rc.local chmod +x /etc/rc.d/rc.local /etc/rc.d/rc.local chown -R redis.redis ${INSTALL_DIR} systemctl daemon-reload systemctl enable redis.service systemctl start redis.service [ $? -eq 0 ] && action "Redis 启动" || { action "Redis 启动" false ;exit ;} [ $? -eq 0 ] && $COLOR"Redis安装成功"$END } check install_redis
安装完redis服务后修改配置文件，配置一主二从。 master(10.0.0.105)修改以下配置，重启服务 vim /apps/redis/etc/redis.conf masterauth 123456 systemctl restart redis.service slave1(10.0.0.106),slave2(10.0.0.107)修改以下配置，重启服务 vim /apps/redis/etc/redis.conf replicaof 10.0.0.105 6379 masterauth 123456 systemctl restart redis.service

2、实现 redis cluster 得部署
老规矩先部署redis服务（所有服务器都操作）
bash install_redis.sh
修改redis.conf文件启动cluster（所有服务器都操作） sed -i.bak -e '/^# masterauth.*/c masterauth 123456' -e '/# cluster-enabled yes/c cluster-enabled yes' -e '/# cluster-enable yes/a cluster-enable yes' -e '/# cluster-config-file nodes-6379.conf/a cluster-config-file nodes-6379.conf' -e '/cluster-require-full-coverage yes/c cluster-require-full-coverage no' /apps/redis/etc/redis.conf [root@centos7 ~]#systemctl restart redis [root@centos7 ~]#ss -ntl State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 100 127.0.0.1:25 *:* LISTEN 0 511 *:16379 *:* LISTEN 0 511 *:6379 *:* LISTEN 0 128 *:22 *:* LISTEN 0 100 [::1]:25 [::]:* LISTEN 0 128 [::]:22 [::]:*
