MongoDB有一个主要特性就是复制,有多种复制形式,其中,主从复制是比较常用的一种。

主从复制的工作原理:首先要有两个或更多的服务器,其中一个是主节点,负责处理客户端的请求,其他的都是从节点,,负责映射主节点的数据。主节点记录在其上执行的所有操作,从节点定期轮询主节点获得的这些操作,然后执行这些操作。由于从节点和主节点执行了相同的操作,从节点就能保持与主节点的数据同步。

实战讲解一下MongoDB的搭建和主从复制,因为只有一台服务器,所以只能通过修改端口号实现MongoDB的主从,而不是通过多台服务器实现。其实原理是一样的~,只是这样做实际意义不大~

之前已经装了一个版本的MongoDB(2.6.11),既然现在mongodb已经更新到了3.0.6,那么从库就特意使用3.0.6,反正是测试用途,就不管那么多了~ 
 
安装

mongodb下载地址

下载mongodb3.0.6执行文件包,并解压,把二进制执行文件放在/usr/local/mongo3.0.6目录
 
配置
 
主库配置

# mongod.conf
 
#where to log
logpath=/var/log/mongodb/mongod-27017.log
 
logappend=true
 
# fork and run in background
fork=true
 
port=27017
 
#dbpath=/var/lib/mongo
dbpath=/data/mongodb/mongo-27017
 
# location of pidfile
pidfilepath=/var/run/mongodb/mongod-27017.pid
 
bind_ip=127.0.0.1,192.168.56.61
 
#noauth=true
 
# Ignore query hints
#nohints=true
 
# Disable the HTTP interface (Defaults to localhost:27017).
nohttpinterface = false
rest = true
 
master = true
 
从库配置

# mongod.conf
 
#where to log
logpath=/var/log/mongodb/mongod-27018.log
 
logappend=true
 
# fork and run in background
fork=true
 
port=27018
 
#dbpath=/var/lib/mongo
dbpath=/data/mongodb/mongo-27018
 
# location of pidfile
pidfilepath=/var/run/mongodb/mongod-27018.pid
 
# Listen to local interface only. Comment out to listen on all interfaces.
bind_ip=127.0.0.1,192.168.56.61
 
#noauth=true
 
# Ignore query hints
#nohints=true
 
# Disable the HTTP interface (Defaults to localhost:27018).
nohttpinterface = false
rest = true
 
slave = true
source = 127.0.0.1:27017
 
启动

# 主库启动
/usr/local/mongo2.6.11/mongod -f /etc/mongod/mongod-27017.conf
 
# 从库启动
/usr/local/mongo3.0.6/mongod -f /etc/mongod/mongod-27018.conf
 
 
认证

  不同版本的mongodb开始auth模式可以通过下面的方法来实现

  1. 先把所有主从mongodb设为unauth模式

  2. 在master添加一个账号,这样slave也就自动同步了该账号

  3. 把所有主从mongodb开启auth模式

How to use MySQL functions for data processing and calculationHow to use MySQL functions for data processing and calculationApr 29, 2025 pm 04:21 PM

MySQL functions can be used for data processing and calculation. 1. Basic usage includes string processing, date calculation and mathematical operations. 2. Advanced usage involves combining multiple functions to implement complex operations. 3. Performance optimization requires avoiding the use of functions in the WHERE clause and using GROUPBY and temporary tables.

An efficient way to batch insert data in MySQLAn efficient way to batch insert data in MySQLApr 29, 2025 pm 04:18 PM

Efficient methods for batch inserting data in MySQL include: 1. Using INSERTINTO...VALUES syntax, 2. Using LOADDATAINFILE command, 3. Using transaction processing, 4. Adjust batch size, 5.

Steps to add and delete fields to MySQL tablesSteps to add and delete fields to MySQL tablesApr 29, 2025 pm 04:15 PM

In MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.

How to analyze the execution plan of MySQL queryHow to analyze the execution plan of MySQL queryApr 29, 2025 pm 04:12 PM

Use the EXPLAIN command to analyze the execution plan of MySQL queries. 1. The EXPLAIN command displays the execution plan of the query to help find performance bottlenecks. 2. The execution plan includes fields such as id, select_type, table, type, possible_keys, key, key_len, ref, rows and Extra. 3. According to the execution plan, you can optimize queries by adding indexes, avoiding full table scans, optimizing JOIN operations, and using overlay indexes.

How to use MySQL subquery to improve query efficiencyHow to use MySQL subquery to improve query efficiencyApr 29, 2025 pm 04:09 PM

Subqueries can improve the efficiency of MySQL query. 1) Subquery simplifies complex query logic, such as filtering data and calculating aggregated values. 2) MySQL optimizer may convert subqueries to JOIN operations to improve performance. 3) Using EXISTS instead of IN can avoid multiple rows returning errors. 4) Optimization strategies include avoiding related subqueries, using EXISTS, index optimization, and avoiding subquery nesting.

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
