Failed to start mongod.service: Unit not found

其实自己用惯的是MYSQL，然后项目最后一步完善数据读写的部分，本来打算用mysql的，然而在centOS系统上发现安装总是出问题，后来查找一下资料，发现centOS系统上一般用的是Mariadb，这是一个MYSQL的分支，说是因为甲骨文收购了MYSQL后，为了避免闭源的风险，社区开始使用并维护这个MariaDB。

然后我安装Maria，一直卡在那里。。。

可是话说为什么我一个前端，要搞这些东西呢。。。

然后我还是退出来使用mongodb算了。。。

然后启动mongodb的时候报这个错误：Failed to start mongod.service: Unit not found

此刻的心情。。。。

再是一番查阅，看了好多帖子终于找到解决方法：

1创建配置文件：

sudo nano /etc/systemd/system/mongodb.service

2.在里面追加文本：

 1 [Unit]
 2 Description=High-performance, schema-free document-oriented database
 3 After=network.target
 4
 5 [Service]
 6 User=mongodb
 7 ExecStart=/usr/bin/mongod --quiet --config /etc/mongod.conf
 8
 9 [Install]
10 WantedBy=multi-user.target

3.按ctrl+X退出

4.启动服务

sudo systemctl start mongodb
sudo systemctl status mongodb

5.让它永久启动

sudo systemctl enable mongodb

莫名心累。。。

CentOS7安装mysql后无法启动服务，提示Failed to start mysqld.service: Unit not found

首先:需要更新你的yum源,保证yum源最新. 1.安装: yum install -y mariadb-server 2.启动maria DB服务: systemctl start mariadb.service (说明:CentOS 7.x开始,CentOS开始使用systemd服务来代替daemon,原来管理系统启动和管理系统服务的相关命令全部由systemctl命令来代替.) 3.将mariadb服务添加至开机自启动: systemctl enable mariadb.service 原
