部署MongoDB-4.2.7

二进制部署很简单

创建存放软件目录下载解压

存放数据和日志及配置文件路径需要手工进行创建

mkdir -p /application/tools/
cd /application/tools/
wget http://downloads.mongodb.org/linux/mongodb-linux-x86_64-rhel70-4.2.7.tgz
tar xf mongodb-linux-x86_64-rhel70-4.2.7.tgz -C /application/
mv /application/mongodb-linux-x86_64-rhel70-4.2.7 /application/mongodb-4.2.7
ln -sv /application/mongodb-4.2.7/ /application/mongodb
mkdir -p /application/mongodb/{data,logs,conf}
echo 'export PATH=/application/mongodb/bin:$PATH' >>/etc/profile
source /etc/profile

 使用systemd进行管理

cat >/usr/lib/systemd/system/mongodb.service <<EOF
[Unit]
Description=mongodb
After=network.target
 
[Service]
Type=forking
PIDFile=/tmp/mongod.pid
RuntimeDirectory=mongodb
RuntimeDirectoryMode=0751
ExecStart=/application/mongodb/bin/mongod --config /application/mongodb/conf/mongodb.conf
ExecStop=/application/mongodb/bin/mongod --shutdown --config /application/mongodb/conf/mongodb.conf
PrivateTmp=false
 
[Install]
WantedBy=multi-user.target
EOF

增加执行权限设置开机自启

systemctl daemon-reload 
chmod +x /usr/lib/systemd/system/mongod.service
systemctl start mongod.service
systemctl stop mongod.service
systemctl restart mongod.service
systemctl enable mongod.service
