部署mongDB数据库服务

在192.168.4.51主机

配置步骤：

装包

ls mongodb-linux-x86_64-rhel70-3.6.3.tgz

tar -zxf mongodb-linux-x86_64-rhel70-3.6.3.tgz

cp -r mongodb-linux-x86_64-rhel70-3.6.3/bin /usr/local/mongodb/

cd /usr/local/mongodb/

mkdir -p etc log data/db

修改配置服务

vim /usr/local/mongodb/etc/mongodb.conf

dbpath=/usr/local/mongodb/data/db

fork=true

logpath=/usr/local/mongodb/log/mongodb.log

logappend=true

bind_ip=192.168.4.51

port=27051

vim /etc/profile

export PATH=/usr/local/mongodb/bin:$PATH

source /etc/profile

Vim /etc/bashrc

alias mstop=’mongod --shutdown -f /usr/local/mongodb/etc/mongodb.conf’

alias mstar=’mongod -f /usr/local/mongodb/etc/mongodb.conf’

source /etc/bashrc

启动服务

Mstart

查看服务信息

ss -unltp | grep :27051

tcp LISTEN 0 128 192.168.4.51:27051 *:* users:(("mongod",pid=1465,fd=11))

连接服务信息

mongo --host 192.168.4.51 --port 27051

杀掉进程

Killall -9 mongod
