Go language (Golang) is an efficient, reliable, and simple programming language developed by Google. In recent years, the Go language has gradually moved to the forefront of the programming world with its greater advantages, becoming the language of choice in cloud computing, big data, high concurrency and other fields, and its user base has become increasingly large. This article mainly introduces the installation process of golang 1.7.5.
1. Preparations before installation
During the installation process, we need to configure some environment variables in the Linux system environment. The specific operations are as follows:
1. Check the gcc version installed in the system:
gcc --version
If gcc is not installed in the system or the version is too low, you need to install a newer version of gcc:
sudo apt-get update sudo apt-get install gcc
2. Check whether Mercurial has been installed in the system :
hg --version
If Mercurial is not installed in the system, you need to install Mercurial:
sudo apt-get update sudo apt-get install mercurial
2. Installation of golang 1.7.5
1. Download the source code from the official website
First, you need to download the latest version of golang source code from the golang official website (https://golang.org/dl/). Unzip the downloaded compressed file.
2. Configure environment variables
(1) Set the GOPATH environment variable:
export GOPATH=/usr/local/go
(2) Add the Go language binary file directory to the system PATH environment variable:
export PATH=$PATH:/usr/local/go/bin
(3) Save the environment variable configuration:
source ~/.bash_profile
(4) Test whether the environment variable is configured successfully through verification:
go version
If the version number of golang 1.7.5 is output , the installation is successful.
3. Test and verify whether golang is installed successfully
Write a Hello world program to test and verify whether golang is installed successfully:
1. Create directory:
mkdir -p $GOPATH/src/hello
2. Create the main.go file in the hello directory:
package main import "fmt" func main() { fmt.Println("Hello, world!") }
3. Run the code:
go run main.go
If the terminal outputs the words Hello, world!, the verification is passed and golang is installed. .
Summary
Installing golang 1.7.5 is relatively simple. It mainly requires configuring system environment variables. Through the above steps, there should be no problem installing golang 1.7.5 in the Linux system. I hope this article will be helpful to you when installing golang 1.7.5.

The main differences between Golang and Python are concurrency models, type systems, performance and execution speed. 1. Golang uses the CSP model, which is suitable for high concurrent tasks; Python relies on multi-threading and GIL, which is suitable for I/O-intensive tasks. 2. Golang is a static type, and Python is a dynamic type. 3. Golang compiled language execution speed is fast, and Python interpreted language development is fast.

Golang is usually slower than C, but Golang has more advantages in concurrent programming and development efficiency: 1) Golang's garbage collection and concurrency model makes it perform well in high concurrency scenarios; 2) C obtains higher performance through manual memory management and hardware optimization, but has higher development complexity.

Golang is widely used in cloud computing and DevOps, and its advantages lie in simplicity, efficiency and concurrent programming capabilities. 1) In cloud computing, Golang efficiently handles concurrent requests through goroutine and channel mechanisms. 2) In DevOps, Golang's fast compilation and cross-platform features make it the first choice for automation tools.

Golang and C each have their own advantages in performance efficiency. 1) Golang improves efficiency through goroutine and garbage collection, but may introduce pause time. 2) C realizes high performance through manual memory management and optimization, but developers need to deal with memory leaks and other issues. When choosing, you need to consider project requirements and team technology stack.

Golang is more suitable for high concurrency tasks, while Python has more advantages in flexibility. 1.Golang efficiently handles concurrency through goroutine and channel. 2. Python relies on threading and asyncio, which is affected by GIL, but provides multiple concurrency methods. The choice should be based on specific needs.

The performance differences between Golang and C are mainly reflected in memory management, compilation optimization and runtime efficiency. 1) Golang's garbage collection mechanism is convenient but may affect performance, 2) C's manual memory management and compiler optimization are more efficient in recursive computing.

Golang and Python each have their own advantages: Golang is suitable for high performance and concurrent programming, while Python is suitable for data science and web development. Golang is known for its concurrency model and efficient performance, while Python is known for its concise syntax and rich library ecosystem.
