Mongodb-Centos7
安装之前准备工作
下载地址:https://www.mongodb.org/dl/linux
环境说明：下载地址
1系统虚拟机信息：CentOS7 X86_64位；
2软件及版本：mongodb-linux-x86_64-3.6.3.tgz；Xshell工具
MongoDB 提供了 linux 各发行版本 64 位的安装包，你可以在官网下载安装包，地址如下：mongodb官网，进入官网，如下图所示：
点击Download,进入下载页面：
选择版本：Linux 64-bit legacy x64,点击DOWNLOAD,点击下载。保存到本地。
安装
启动CentOS7，xshell连接到CentOS7，并且将mongodb-linux-x86_64-3.6.3.tgz上传到CentOS7的/usr/local，具体上传filezilla工具。上传以后列表如下图所示：
解压缩：tar zxvf mongodb-linux-x86_64-3.6.3.tgz
重命名: mv mongodb-linux-x86_64-3.6.3 mongodb
删除: rm -rf mongodb-linux-x86_64-3.6.3.tgz
解压后然后将mongodb移动到/usr/local下的文件如下图所示：
然后将mongodb移动到/usr/local下
mv mongodb /usr/local进入mongodb目录,创建data目录,logs目录和log文件
cd mongodb && mkdir data logs && touch /usr/local/mongodb/logs/log && mkdir conf && cd conf && touch mongo.conf && vim mongo.conf
touch conf/mongo.conf进入/usr/local/mongodb/bin目录下，启动mongodb服务
方式1:配置启动,将以下配置写入mongo.conf
# 配置文件
# 数据指定位置
dbpath = /usr/local/mongodb/data
# 日志指定位置
logpath = /usr/local/mongodb/logs/log
# 每个数据库将被保存在一个单独的目录
directoryperdb = false
# 日志追加形式写入
logappend = true
port = 27017
# 守护进程启动
fork = true
# 指定可连接的主机
bind_ip = 0.0.0.0
# 启动验证 [配置完验证用户后启用]
# auth = false
同时修改/etc/mongod.conf文件,对其进行修改,mongodb安装好后开机自启会加载
logpth dbpath bindip
之后重启开机自启脚本
vim /etc/init.d/mongodb 脚本
#!/bin/sh
#
#chkconfig: 2345 80 90
#description: mongodb
start() {
/usr/local/mongodb/bin/mongod -f /usr/local/mongodb/conf/mongo.conf
}
stop() {
/usr/local/mongodb/bin/mongod -f /usr/local/mongodb/conf/mongo.conf --shutdown
}
case "$1" in
start)
start
;;
stop)
stop
;;
restart)
stop
start
;;
*)
echo $"Usage: $0 {start|stop|restart}"
exit 1
esac 生效
cd /etc/init.d
chkconfig --add mongodb
chmod +x mongodb
chkconfig mongodb on 启动
mongod -f /usr/local/mongodb/conf/mongo.conf方式2:参数启动
cd bin/ && ./mongod --dbpath=/usr/local/mongodb/data --logpath=/usr/local/mongodb/logs/log --logappend --bind_ip=0.0.0.0 --port=27017 --fork
其中的--bind_ip=0.0.0.0是为了开启远程客户端连接
启动客户端，进入/usr/local/mongodb/bin目录下
./mongo
解决MongoDB登录的WARNING
1.安装完成运行mongodb警告内容如下：

警告一：
2019-01-17T15:41:50.578+0800 I CONTROL [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/enabled is 'always'.
2019-01-17T15:41:50.578+0800 I CONTROL [initandlisten] ** We suggest setting it to 'never'

2019-01-17T15:41:50.578+0800 I CONTROL [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/defrag is 'always'.
2019-01-17T15:41:50.578+0800 I CONTROL [initandlisten] ** We suggest setting it to 'never'
1.原因自查--解决：
# 在系统 /etc/rc.local 设置 transparent_hugepage 为 never
[root@server_node01#>> /data/db]#cat /etc/rc.local
if test -f /sys/kernel/mm/transparent_hugepage/enabled; then
echo never > /sys/kernel/mm/transparent_hugepage/enabled
fi
if test -f /sys/kernel/mm/transparent_hugepage/defrag; then
echo never > /sys/kernel/mm/transparent_hugepage/defrag
fi
2.添加该文件的可执行权限：
chmod +x /etc/rc.d/rc.local
3.重启下系统：
reboot
警告二：

设置允许访问该mongodb的地址 --bind_ip：
# 配置文件 添加 --bind_ip 指定可连接的主机
# 数据指定位置
dbpath = /data
# 日志指定位置
logpath = /data/db/logs/log
# 每个数据库将被保存在一个单独的目录
directoryperdb = true
# 日志追加形式写入
logappend = true
port = 27017
# 守护进程启动
fork = true
# 指定可连接的主机
bind_ip = 0.0.0.0
# 启动验证 [配置完验证用户后启用]
# auth = true
或者以这种格式启动
./mongod --dbpath=/usr/local/mongodb/data --logpath=/usr/local/mongodb/logs/log --logappend --bind_ip=0.0.0.0 --port=27017 --fork
警告三：
WARNING: Access control is not enabled for the database.
Read and write access to data and configuration is unrestricted.
设置密码访问auth=True：
1.登录mongo设置admin 密码
[root@server_node01#>> /usr/local/mongodb]#mongo
> use admin
> db.createUser({user:"root",pwd:"root",roles:[{role:'root',db:'admin'}]})
2.将配置文件 auth 认证打开
# 数据指定位置
dbpath = /data/db
# 日志指定位置
logpath = /data/db/logs/mongodb.log
# 每个数据库将被保存在一个单独的目录
directoryperdb = true
# 日志追加形式写入
logappend = true
port = 27017
# 守护进程启动
fork = true
# 指定可连接的主机
bind_ip = 0.0.0.0
# 启动验证 [配置完验证用户后启用]
auth = false
重启mongodb 服务
[root@server_node01#>> /data/db]#mongod --shutdown
[root@server_node01#>> /data/db]#mongod -f /usr/local/mongodb/conf/mongod.conf
登录：
[root@server_node01#>> /data/db]#mongo 127.0.0.1:27017/admin -u root -p
警告四：不要用root用户启动 MongoDB服务
