centos7安装mongodb
1.yum安装
1.1 添加清华yum源
cat > /etc/yum.repos.d/mongodb.repo <<'EOF'
[mongodb-org]
name=MongoDB Repository
baseurl=https://mirrors.tuna.tsinghua.edu.cn/mongodb/yum/el$releasever/
gpgcheck=0
enabled=1
EOF
yum makecache
1.2 安装社区版mongodb
安装最新版
yum -y install mongodb-org
安装指定版本
yum -y install mongodb-org-4.2.8 mongodb-org-server-4.2.8 mongodb-org-shell-4.2.8 mongodb-org-mongos-4.2.8 mongodb-org-tools-4.2.8
1.3 启动mongodb
systemctl enable mongod && systemctl start mongod
mongodb监听tcp/27017
$ netstat -ntpl|grep 27017
tcp 0 0 127.0.0.1:27017 0.0.0.0:* LISTEN 17976/mongod
mongodb默认以mongod用运行
$ ps aux|grep [m]ongo
mongod 17976 0.6 7.8 1552904 78904 ? Sl 22:04 0:00 /usr/bin/mongod -f /etc/mongod.conf
1.4 mongodb相关目录文件
mongodb配置文件/etc/mongod.conf
mongodb日志文件/var/log/mongodb/mongod.log
mongodb PID文件/run/mongodb/mongod.pid
mongodb SOCKET文件/tmp/mongodb-27017.sock
mongodb数据目录/var/lib/mongo/
2.二进制安装
2.1 安装依赖包
yum -y install libcurl openssl
2.2 下载二进制包
wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel70-4.2.8.tgz
2.3 解压缩包
tar xf mongodb-linux-x86_64-rhel70-4.2.8.tgz -C /usr/local/
2.4 做软连接
ln -s /usr/local/mongodb-linux-x86_64-rhel70-4.2.8/ /usr/local/mongodb-4.2.8
2.5 导出PATH环境变量
echo 'export PATH=/usr/local/mongodb-4.2.8/bin:$PATH' >/etc/profile.d/mongodb.sh && source /etc/profile
2.6 创建相关目录
# 创建数据、日志、pid、配置文件目录
mkdir -p /data/db/mongodb/{data,log,pid,conf}
2.7 创建mongod用户
useradd mongod -s /sbin/nologin -M
2.8 编辑mongodb配置文件
cat > /data/db/mongodb/conf/mongod.conf <<'EOF'
bind_ip = 10.0.0.31
logpath = /data/db/mongodb/log/mongod.log
logappend = true
pidfilepath = /data/db/mongodb/pid/mongod.pid
dbpath = /data/db/mongodb/data
# 存储引擎，有mmapv1、wiretiger、mongorocks
storageEngine = wiredTiger
# 使用追加的方式写日志
directoryperdb = true
#replSet = replset
#rest = true
oplogSize = 61440
# 是否以守护进程方式运行，如果用supervisor管理就设置为false
fork = false
# 是否启用验证
auth = false
#shardsvr = true
port = 27010
# 每次写入会记录一条操作日志（通过journal可以重新构造出写入的数据）。即使宕机，启动时wiredtiger会先将数据恢复到最近一次的checkpoint点，然后重放后续的journal日志来恢复。
journal = true
#maxConns = 30000
#master = true
#slave = true
#source = 10.31.133.145:27010
#source = 10.47.125.99:27010
#autoresync=true
EOF
2.9 设置目录所有者为mongod
chown -R mongod:mongod /data/db/mongodb
2.10 使用supervisor管理mongodb
cat >/etc/supervisor/config.d/mongodb.ini<<'EOF'
[program:mongodb]
command=/usr/local/mongodb-4.2.8/bin/mongod -f /data/db/mongodb/conf/mongod.conf
directory=/usr/local/mongodb-4.2.8
autostart=true
user=mongod
EOF
$ supervisorctl update mongodb
mongodb: added process group
2.11 查看mongodb运行状态
查看mongodb进程
$ ps aux|grep [m]ongodb
mongod 30352 1.5 2.2 1550840 89140 ? Sl 20:18 0:00 /usr/local/mongodb-4.2.8/bin/mongod -f /data/db/mongodb/conf/mongod.conf
mongodb监听TCP/27010端口
$ netstat -ntpl|grep mongod
tcp 0 0 10.0.0.31:27010 0.0.0.0:* LISTEN 30352/mongod
2.12 连接mongodb

Enable MongoDB's free cloud-based monitoring service, which will then receive and display
metrics about your deployment (disk utilization, CPU, operation statistics, etc).
The monitoring data will be available on a MongoDB website with a unique URL accessible to you
and anyone you share the URL with. MongoDB may use this information to make product
improvements and to suggest MongoDB products and deployment options to you.
To enable free monitoring, run the following command: db.enableFreeMonitoring()
To permanently disable this reminder, run the following command: db.disableFreeMonitoring()
