How to build LNMP environment

This article introduces to you a tutorial on setting up the LNMP environment. It has a certain reference value. Friends in need can refer to it.

1. For the installation process of nginx under Linux system, first go to the website http://nginx.org/download/ to find the version you need to download, and copy the download link address, here it is nginx-1.6. 2 For example, enter the command on the command line:

 cd /usr/local/src  //将安装包下载到/usr/local/src目录下

 wget http://nginx.org/download/nginx-1.6.2.tar.gz

After the download is completed, you will see it in the directory Go to an nginx-1.6.2.tar.gz installation package, decompress the installation package:

 tar zxvf nginx-1.6.2.tar.gz

After decompression, enter the command for installation:

 cd nginx-1.6.2  //切换到解压后的nginx目录

./configure --prefix=/usr/local/nginx   //安装到/usr/local目录下

My server reported an error when executing the above command:

The above error says that the C compiler cannot be found, so install a compiler for you and enter the command:

 yum -y install gcc gcc-c++ autoconf automake make

After execution Then use the installation command ./configure --prefix=/usr/local/nginx. The above error is no longer reported, but a new error is prompted:

HTTP heavy Writing modules requires the PCRE library, so you need to install the PCRE library:

yum install pcre

When I enter the command, it prompts me that the pcre library has been installed. Nothing to do... .

At this time, you need to check whether pcre-devel has been installed. Enter the same command:

yum install pcre-devel

Execute the command, and sure enough it is not. devel, enter y to continue the installation. After completion, execute the installation command again:

./configure --prefix=/usr/local/nginx

As a result, another error was reported:

HTTP GZIP module requires the ZLIB library, but the library is missing. Install the above routine and go through it again. The command:

yum install zlib

prompts me Nothing to do.. ., Haha, continue the command:

 yum install zlib-devel

The devel is missing again. After the installation is completed, execute the installation command again:

 ./configure --prefix=/usr/local/nginx

This time the installation was finally completed, with twists and turns:

Finally execute the compilation command:

make && make install

nginx is much smaller than apache, so the compilation time is also very short. After compilation is completed, switch to the /usr/local/nginx directory and you will see four directories:

conf mainly places configuration files

html mainly places web page files

logs mainly places log files

sbin mainly places binary programs

If you want to start nginx Just enter the command:

 ./sbin/nginx

Note: If you have installed apache before, an error may be reported at this time,

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)    //这是因为你的80端口已经被占用,启动nginx的时候冲突

netstat -tunlp   //查看正在运行的服务或软件

Find the software or service occupying port 80 and close it, then enter the ./sbin/nginx command, If your character is normal, it should have started normally.

2. Install MySQL with yum:

yum install mysql mysql-devel mysql-server

There is nothing to say about this, just y all the way Just install it

3. Install PHP:

First go to the PHP official website to find the required version and download the compressed package. Here we take the php-5.6 version as an example and upload it to the server/usr/local In the /src/ directory, enter the command line mode and enter the command:

tar zxvf php-5.6.36.tar.gz

Decompress and compile. You need to add some support during compilation, such as mysqlnd , ttf, gd, etc.:

./configure --prefix=/usr/local/php --with-mysql=mysqlnd --enable-mysqlnd --with-gd --enable-gd-native-ttf --enable-gd-jis-conv --enable-fpm

When compiling, you need to pay attention to the possibility that errors may be prompted, such as the lack of certain packages. At this time, install nginx using the same routine as above. For example, when I encounter an error that libxml2 is not found, I directly command:

 yum install libxml2

. It prompts me Nothing to do... Another command:

yum install libxml2-devel

Sure enough, devel is missing again. Compile again after the installation is complete. Don’t forget after completion:

make && make install

Compile After completion, you still need to do some PHP configuration operations:

cp /usr/local/src/php-5.6.36/php.ini-development php.ini-production

cp /usr/local/src/php-5.6.36/php.ini-development ./lib/php.ini

cp etc/php-fpm.conf.default etc/php-fpm.conf

The LNMP setup has been completed here. Don’t forget to cd /usr/local/php directory to start PHP:

./sbin/php-fpm

netstat -tunlp
