mongodb standalone部署

系统准备

ulimit 设置

cat <<EOF>>/etc/security/limits.conf
*  -      nofile 131072
*  hard   nofile 131072
*  -      nproc  192276
*  hard   nproc  192276
*  -      stack  unlimited
*  hard   core   2048000
mongo hard cpu  unlimited
mongo soft cpu  unlimited
mongo hard memlock unlimited
mongo soft memlock unlimited
mongo hard nofile 131072
mongo soft nofile 131072
mongo hard nproc 192276
mongo soft nproc 192276
mongo hard fsize unlimited
mongo soft fsize unlimited
mongo hard as unlimited
mongo soft as unlimited
EOF

selinux

sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

系统参数设置

cat > /etc/sysctl.conf << here
vm.overcommit_memory=1
#尽量不用swap虚拟内存
vm.swappiness=1
#禁用zone_reclaim_mode
vm.zone_reclaim_mode=0 
#系统Dirty ratio刷新
vm.dirty_ratio = 15
vm.dirty_background_ratio = 5
#网络设置
net.core.somaxconn = 4096
net.ipv4.tcp_fin_timeout = 30
net.ipv4.tcp_keepalive_intvl = 30
net.ipv4.tcp_keepalive_time = 120
net.ipv4.tcp_max_syn_backlog = 4096
net.ipv4.tcp_keepalive_probes = 6
here
sysctl -p

禁用THP

$ echo "never" > /sys/kernel/mm/transparent_hugepage/enabled
$ echo "never" > /sys/kernel/mm/transparent_hugepage/defrag

#  vi /etc/rc.local
echo 'never' > /sys/kernel/mm/transparent_hugepage/enabled
echo 'never' > /sys/kernel/mm/transparent_hugepage/defrag

chmod a+x /etc/rc.local

用户添加

useradd mongo
echo "mongo" | passwd --stdin mongo


配置用户sodu权限
cat >> /etc/sudoers << here
mongo ALL=(ALL) NOPASSWD:ALL
here

安装配置

硬件检查：

cat /proc/cpuinfo

新装机器是否满足需查看

https://www.mongodb.com/docs/manual/administration/production-notes/#platform-support-notes

依赖包安装

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
cd  /etc/yum.repos.d/
sed -i 's/$releasever/7/g' *.repo
yum install -y epel-release
yum -y install yum-utils glibc
yum -y install openssl11*

下载

https://www.mongodb.com/download-center/community/releases/archive

使用V4.4版本

下载解压

wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel70-4.4.28.tgz
tar zxvf mongodb-linux-x86_64-rhel70-4.4.28.tgz -C /usr/local/
ln -s  /usr/local/mongodb-linux-x86_64-rhel70-4.4.28  /usr/local/mongodb
vi /etc/profile
MONGO_PATH=/usr/local/mongodb/bin &&  PATH=$PATH:$MONGO_PATH
source /etc/profile

目录规划及赋权

mkdir -p /data/mongodb/standalone/{keyfile,data,log,conf}
chown -R mongo:mongo /usr/local/mongodb
chown -R mongo:mongo /data/mongodb/

配置文件

注：为了模拟变更，我们暂时不开oplog，等下次由standalone变更为replication set 才设置

#standalone
vi /data/mongodb/standalone/conf/mongo.conf 
systemLog:
  destination: file
  path: "/data/mongodb/standalone/log/config.log"
  quiet: true
  logAppend: true
  timeStampFormat: iso8601-utc

  bindIp: 0.0.0.0
  port: 27017
operationProfiling:
  slowOpThresholdMs: 100
  mode: "slowOp"

启动

mongod -f /data/mongodb/standalone/conf/mongo.conf 

MongoDB工具包
注:4.4开始工具包需要单独安装，mongo shell也需要单独下载。

非必选项，不影响CURD操作

下载测试数据

wget https://static.crunchbase.com/data_crunchbase/bulk_export_sample.tar.gz
tar -ztvf  bulk_export_sample.tar.gz
tar -zxvf  bulk_export_sample.tar.gz
mongoimport --host 127.0.0.1:27017 --db testdb --collection category_groups --type csv --file /home/mongo/category_groups.csv --headerline

查询testdb库数据是否导入

mongosh "mongodb://192.168.0.211:27017" 
或者
mongo --host 192.168.0.211 -port 27017
