二进制安装MongoDB

1、下载mongodb

cd /usr/local/src/
wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-4.0.5.tgz
tar xf mongodb-linux-x86_64-4.0..tgz
mv mongodb-linux-x86_64-4.0. /usr/local/
ln -s /usr/local/mongodb-linux-x86_64-4.0.   /usr/local/mongodb

2、创建数据与日志存放目录

mkdir  /data/mongodata -p
mkdir  /data/logs/mongolog -p

3、环境变量设置

echo 'export PATH=$PATH:/usr/local/mongodb/bin' >>/etc/profile
source  /etc/profile
#测试
[root@iZm5e68ouhl866li7184cnZ src]# mongo -version
MongoDB shell version v4.0.5
git version: 3739429dd92b92d1b0ab120911a23d50bf03c412
allocator: tcmalloc
modules: none
build environment:
    distarch: x86_64
    target_arch: x86_64

4、创建配置文件mongodb.conf

mkdir  /usr/local/mongodb/conf
[root@iZm5e68ouhl866li7184cnZ src]# cat /usr/local/mongodb/conf/mongodb.conf
#数据文件存放目录
dbpath = /data/mongodata
#日志文件存放目录
logpath = /data/logs/mongolog/mongodb.log
#端口
port =
#以守护程序的方式启用，即在后台运行
fork = true
#监听ip
bind_ip=0.0.0.0
#最大连接数
maxConns=
# pid文件
pidfilepath=/tmp/mongod.pid
#开启认证
auth = true

5、配置启动文件

[root@iZm5e68ouhl866li7184cnZ src]# cat   /usr/lib/systemd/system/mongodb.service
[Unit]
Description=mongodb
After=network.target

[Service]
Type=forking
PIDFile=/var/run/mongod.pid
ExecStart=/usr/local/mongodb/bin/mongod -f /usr/local/mongodb/bin/mongodb.conf
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true

[Install]
WantedBy=multi-user.target

6、启动

systemctl  start  mongodb.service 

[root@iZm5e68ouhl866li7184cnZ ~]# systemctl  status mongodb.service
● mongodb.service - mongodb
   Loaded: loaded (/usr/lib/systemd/system/mongodb.service; disabled; vendor preset: disabled)

#查看
[root@iZm5e68ouhl866li7184cnZ ~]# ss -lntp|grep mongod
LISTEN                     *:                    *:*                   users:(("mongod",pid=,fd=))

7、使用测试

[root@iZm5e68ouhl866li7184cnZ ~]# mongo  --host 127.0.0.1
