一、目录结构与使用说明¶
1.1 目录中的文件¶
install_redis_single.sh：Redis 单实例安装脚本。install_redis_multi.sh：Redis 多实例安装脚本。ReadMe.md：说明软件包和脚本需要放在同一目录下。
1.2 这组脚本的共通思路¶
- 自动安装编译依赖。
- 下载或复用 Redis 源码包。
- 编译安装到统一目录。
- 生成配置文件并注册 systemd 服务。
- 调整
somaxconn、vm.overcommit_memory和透明大页设置。
二、单实例脚本整理¶
2.1 单实例部署的关键流程¶
REDIS_VERSION=redis-7.4.2
PASSWORD=<your-password>
INSTALL_DIR=/apps/redis
make -j "$CPUS" USE_SYSTEMD=yes PREFIX="${INSTALL_DIR}" install
cp redis.conf "${INSTALL_DIR}/etc/"
sed -i.bak \
-e "/^bind/c bind 0.0.0.0" \
-e "\$a requirepass ${PASSWORD}" \
-e "/^dir .*/c dir ${INSTALL_DIR}/data/" \
"${INSTALL_DIR}/etc/redis.conf"
2.2 发布时建议顺手修正的小问题¶
原单实例脚本里使用了 make -j $CUPS，但前面定义的变量名是 CPUS。正式发布前建议统一成 make -j "$CPUS"，否则并发编译参数可能为空。
三、多实例脚本整理¶
3.1 多实例端口规划¶
for PORT in "${REDIS_PORTS[@]}"; do
INSTANCE_DIR="${INSTALL_DIR}/${PORT}"
mkdir -p "${INSTANCE_DIR}/"{etc,log,data,run}
cp redis.conf "${INSTANCE_DIR}/etc/redis_${PORT}.conf"
sed -i.bak \
-e "s/^port .*/port ${PORT}/" \
-e "s#^dir .*#dir ${INSTANCE_DIR}/data#" \
-e "s#^logfile .*#logfile ${INSTANCE_DIR}/log/redis_${PORT}.log#" \
"${INSTANCE_DIR}/etc/redis_${PORT}.conf"
done
3.2 systemd 模板化服务¶
cat > "/etc/systemd/system/redis@${PORT}.service" <<EOF
[Unit]
Description=Redis Server on port ${PORT}
After=network.target
[Service]
ExecStart=/apps/redis/bin/redis-server ${INSTANCE_DIR}/etc/redis_${PORT}.conf --supervised systemd
User=redis
Group=redis
EOF
四、发布前建议¶
4.1 建议补充的验证命令¶
redis-cli -a <your-password> pingsystemctl status redissystemctl status redis@6379
五、完整脚本¶
