Centos7 how to build lnmp development environment, I believe that many inexperienced people do not know what to do, so this paper summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

Nginx installation

1. Add source

Sudo rpm-Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

2. Install Nginx

Sudo yum install-y nginx

3. Start Nginx and set the boot to run automatically.

Sudo systemctl start nginx.servicesudo systemctl enable nginx.serviceMySql installation

1. Check the linux operating system version and system kernel version

# cat / etc/redhat-release View operating system version

# uname-r View the kernel version of the system

2. Download the corresponding version of MySQL installation file

1. Download address; https://dev.mysql.com/downloads/mysql/

2. Select the corresponding Linux version and x86/x64 to download

You can choose RPM Bundle. After downloading, remember to decompress tar-xvf xxx.tar.

Wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.22-1.el7.x86_64.rpm-bundle.tar

You can also refine the download, download the required mysql components, there are four: server, client, common, libs

3. Uninstall the old version of MySql

(1) View the old version of MySql

Rpm-qa | grep mysql

(2) delete the old components one by one

Use the command rpm-e {- file-name} to remove. There may be dependencies when removing. You should delete it from back to front.

4. Use the rpm command to install MySql components

Use the command rpm-ivh {- file-name} to install.

Install RPM package dependencies according to dependencies: common → libs → client → server

Rpm-ivh mysql-community-common-5.7.22-1.el7.x86_64.rpm

Rpm-ivh mysql-community-libs-5.7.22-1.el7.x86_64.rpm

Rpm-ivh mysql-community-client-5.7.22-1.el7.x86_64.rpm

Rpm-ivh mysql-community-server-5.7.22-1.el7.x86_64.rpm

Generate the directory when you are finished:

a)。 Generate my.cnf files and my.cnf.d folders under / etc/

b)。 Produce the following three folders under / var/lib/: mysql,mysql-files,mysql-keyring

c)。 Generate mysqld.log file under / var/log/

d)。 Generate the mysqld directory under / var/run/

5. Start the MySQL service

Service mysqld start

6. Boot up

# systemctl enable mysqld

# systemctl daemon-reload

7. Modify the root local login password

1) View mysql password

# grep 'temporary password' / var/log/mysqld.log

2) Connect to mysql

# mysql-uroot-p

3) change the password [Note: the semicolon must follow]

# ALTER USER 'root'@'localhost' IDENTIFIED BY' MyNewPass4passport'

Or:

# set password for 'root'@'localhost'=password (' MyNewPass4passport')

# show variables like'% password%'

4) add Telnet user

Mysql > GRANT ALL PRIVILEGES ON *. * TO 'username'@'%' IDENTIFIED BY' password' WITH GRANT OPTION
