组件安装

# 给CentOS7安装remi源
sudo yum --assumeyes install http://rpms.remirepo.net/enterprise/remi-release-7.rpm
# 确认包信息
yum --enablerepo=remi info redis
# 安装redis
sudo yum --enablerepo=remi --assumeyes install redis

单机部署

部署服务

# 准备工作目录
rm --recursive --force ~/redis-singleton
mkdir --parents ~/redis-singleton
# 复制样板文件然后配置好
sudo cp /etc/redis.conf ~/redis-singleton/
sudo cp /usr/lib/systemd/system/redis.service ~/redis-singleton/
sudo chown --recursive ${USER}:${USER} ~/redis-singleton
# 端口逐个配置和启动
for port in 6379;

    # 禁用后停止服务

    # 确保数据目录已创建且权限正确

    # 启用后启动服务
    sudo systemctl enable redis-singleton-$port.service;

    # 查看服务状态

连接服务

redis-cli -c -h 127.0.0.1 -p 6379

销毁服务

# 端口逐个停止和清理
for port in 6379;
do
    # 禁用后停止服务
    if [ -f /usr/lib/systemd/system/redis-singleton-$port.service ];
    then
        sudo systemctl disable redis-singleton-$port.service;
        sudo systemctl stop redis-singleton-$port.service;

    fi;
    # 清理配置文件
    if [ -f /etc/redis-singleton-$port.conf ]; then sudo rm --force /etc/redis-singleton-$port.conf; fi;
    # 清理所有数据
