MongoDB安装
1.上传mongodb包
[root@long ~]# ll
-rw-r--r-- 1 root root 100351280 Jul 6 2019 mongodb-linux-x86_64-3.6.13.tgz
2.文件放于/usr/local/mongodb目录下
cd /usr/local
tar xf mongodb-linux-x86_64-3.6.13.tgz #解压文件
mv mongodb-linux-x86_64-3.6.13/ /usr/local/mongodb #移动文件
3.配置环境变量
vi /etc/profile
export MONGODB_HOME=/usr/local/mongodb
export PATH=$PATH:$MONGODB_HOME/bin
4.mongdb启动配置
#创建db和log目录
cd /usr/local/mongodb
mkdir data
cd data
mkdir db
mkdir log
#进入mongodb的bin目录，配置文件可以自定义位置，我就把它放在了bin目录下
cd /usr/local/mongodb/bin
[root@long bin]# vim mongodb.conf
dbpath = /usr/local/mongodb/data/db #数据文件存放目录
logpath = /usr/local/mongodb/logs/mongodb.log #日志文件存放目录
port = 27017 #端口
fork = true #以守护程序的方式启用，即在后台运行
#nohttpinterface = true
#网上很多添加这句nohttpinterface=true，但是启动会报错，所以就去掉了
加上nohttpinterface = true启动报错提示如下:
[root@long bin]# ./mongod -f mongodb.conf
Error parsing INI config file: unrecognised option 'nohttpinterface'
try './mongod --help' for more information
注释掉后启动
[root@long bin]# ./mongod -f ./mongodb.conf
about to fork child process, waiting until server is ready for connections.
forked process: 8092
child process started successfully, parent exiting
[root@long bin]# ps aux|grep mongo
root 8092 0.2 4.3 989232 44372 ? Sl 10:39 0:03 ./mongod -f ./mongodb.conf
root 8173 0.0 0.0 112660 968 pts/0 R+ 11:03 0:00 grep --color=auto mongo
5.进入mongo
[root@long bin]# ./mongo
