mongodb的安装部署-备份

1.安装部署

wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.4.10.tgz
tar -zxf mongodb-linux-x86_64-3.4.7.tgz
mv mongodb-linux-x86_64-3.4.10 /usr/local/mongodb
mkdir /usr/local/mongodb/data
mkdir /usr/local/mongodb/logs

  mkdir conf
  cd conf/

2.cat /etc/profile

export MONGODB_HOME=/usr/local/mongodb
export PATH=$PATH:$MONGODB_HOME/bin
source /etc/profile

3.配置文件

[root@k8s ~]# cat /usr/local/mongodb/conf/mongodb.conf

port=27017
dbpath=/usr/local/mongodb/data
logpath=/usr/local/mongodb/logs/mongodb.log
pidfilepath=/usr/local/mongodb/mongo.pid
fork=true
logappend=true
auth=true

4.启动服务

./bin/mongod --config ./conf/mongodb.conf

 ---------------------------------------------------------------------------

1.主要文件

[root@k8s mongodb]# tree
.
├── back_mongodb.sh
├── db_file.txt
├── load_mongodb.sh
└── vars_config.conf

2.备份脚本

[root@k8s mongodb]# cat back_mongodb.sh
#!/bin/bash
source ./vars_config.conf
if [ ! -d "$OUTPUT_DIR" ]; then
  mkdir -p "$OUTPUT_DIR"
fi

for db in `cat $DB_FILE`
    do
    $MONGODUMP_CMD  -h ${HOST}:${PORT}-d $db -o $DUMP_MONGODB
    done
# 删除天之前的备份数据
find /data/backup/ -mtime +30 -name "mongodb*" -exec rm -rf {} \;

3.变量文件

[root@k8s mongodb]# cat vars_config.conf
HOST=""
PORT=""
OUTPUT_DIR="/data/backup/mongodb$(date +%Y%m%d%H%M%S)"
DB_FILE="/opt/mongodb/db_file.txt"
MONGODUMP_CMD="/usr/local/mongodb/bin/mongodump"
MONGORESTORE_CMD="/usr/local/mongodb/bin/mongorestore"

4.数据库名文件

[root@k8s mongodb]# cat db_file.txt
