The process of LNMP environment construction using source code (details)
The process of LNMP environment construction using source code (details)
The content of this article is about the process of LNMP recording the environment construction in the form of source code (details). It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.
LNMP refers to the environment for building websites using PHP MYSQL NGIX under Linux.
Nginx is a high-performance HTTP and reverse proxy server, as well as an IMAP/POP3/SMTP proxy server. Nginx can not only be used as a web server, but also as a load balancer.
MySQL is an open source and free data software. MySQL is a small relational database management system. It is small in size, fast in speed and low in total cost of ownership. Especially because of its characteristics of open source, many small and medium-sized websites In order to reduce the total cost of website ownership, MySQL was chosen as the website database.
PHP is the abbreviation of the English hypertext preprocessing language Hypertext Preprocessor. PHP is an HTML embedded language. It is a scripting language that is executed on the server side and embedded in HTML documents. Its source code is written in C language, so the style is similar to C language and is widely used in construction. Small website.
The following is a record of the establishment process of the LNMP environment. The Linux environment of the subject is a CentOs virtual image.
[Nginx Installation]
The latest stable version of Nginx is 1.14.0. The website address is http://nginx.org/en/download.html. You can download it directly on Windows. rz is uploaded to Linux, or it can be downloaded directly using wget. The download method listed below is the latter.
cd /usr/src #一般将源码放在此目录下 wget http://nginx.org/download/nginx-1.14.0.tar.gz #安装
Note: The installation of nginx depends on the zlib-devel pcre-devel openssl-devel packages, so we need to install these packages before installing nginx. To avoid errors during the installation process.
yum -y install zlib-devel pcre-devel openssl-devel
...
Unzip(tar command)Precompile(Execute configure under the source package),Compile(make),Compile and install(make install).
tar -zxvf nginx-1.14.0.tar.gz #这里解释下加压参数,z代表gzip(也就是后面的.gz文件)x代表加压,v表示显示详细信息,-f使用档案文件或设备(必选参数)
cd nginx-1.14.0 ./configure --prefix=/data/webserver/nginx\ # 指定安装目录为/usr/local/nginx --with-openssl=/usr/include/openssl\ # 启用ssl --with-pcre\ # 启用正规表达式 --with-http_stub_status_module # 安装可以查看nginx状态的程序
…. .. 
configure file in the current directory. After the pre-compilation is completed, we Can be compiled and installed:
make #编译
make install #安装
ls /data/webserver/nginx
/data/webserver/nginx/sbin/nginx #启动nginx /data/webserver/nginx/sbin/nginx -s stop #停止nginx /data/webserver/nginx/sbin/nginx -s relaod #重启nginx
netstat -antlp ¦ grep 80 #nginx占用TCP的80端口由图也可知nginx已启动
yum -y install wget cmake gcc gcc-c++ ncurses ncurses-devel libaio-devel openssl openssl-devel
..........
Then we download the source code: 
wget https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-boost-8.0.11.tar.gz
groupadd mysql useradd -r -g mysql -s /bin/false mysql
mkdir -p /usr/local/mysql mkdir -p /data/mysql
tar -zxf mysql-boost-8.0.11.tar.gz -C /usr/local
编译&安装:
cd /usr/local/mysql-8.0.11 cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DSYSCONFDIR=/etc -DMYSQL_TCP_PORT=3306 -DWITH_BOOST=/usr/local/mysql-8.0.11/boost make && make install
安装成功后我们可启动mysql：
cd /usr/local/mysql bin/mysqld_safe --user=mysql
启动成功，连接mysql
bin/mysql -uroot -p
此时要求输入连接密码，比较旧的版本的mysql安装时默认密码为空，但该5.7之后的版本有默认的密码，由于我们不知道，因此关闭mysql服务后（可直接查询进程根据进程号kill掉或/etc/init.d/mysql stop ），改用跳过密码的方式重新开启mysql服务。
bin/mysqld_safe --user=mysql & skip-grant-tables
重新连接
bin/mysql -uroot
连接成功后修改密码
mysql> UPDATE user SET Password=PASSWORD('newpassword') where USER='root'; mysql> FLUSH PRIVILEGES;
此时重启mysql服务，便可以账号密码方式连接mysql。
【PHP安装】
先安装php依赖包，否则在编译安装php7的过程当中会出现各种报错，安装完成后即可进入下一个环节。
安装扩展包并更新系统内核：
yum install epel-release -y yum update
安装php依赖组件（包含Nginx依赖），前面nginx以及mysql安装过的可以忽略，也可以直接复制运行，会跳过已安装的依赖：
yum -y install wget vim pcre pcre-devel openssl openssl-devel libicu-devel gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel ncurses ncurses-devel curl curl-devel krb5-devel libidn libidn-devel openldap openldap-devel nss_ldap jemalloc-devel cmake boost-devel bison automake libevent libevent-devel gd gd-devel libtool* libmcrypt libmcrypt-devel mcrypt mhash libxslt libxslt-devel readline readline-devel gmp gmp-devel libcurl libcurl-devel openjpeg-devel
........
创建用户和组，并下载php安装包解压：
cd /tmp groupadd www useradd -g www www wget http://cn2.php.net/distributions/php-7.2.0.tar.gz tar xvf php-7.2.1.tar.gz cd php-7.2.0
设置变量并开始源码编译：
cp -frp /usr/lib64/libldap* /usr/lib/ ./configure --prefix=/data/webserver/php \ --with-config-file-path=/data/webserver/php/etc \ --enable-fpm \ --with-fpm-user=www \ --with-fpm-group=www \ --enable-mysqlnd \ --with-mysqli=mysqlnd \ --with-pdo-mysql=mysqlnd \ --enable-mysqlnd-compression-support \ --with-iconv-dir \ --with-freetype-dir \ --with-jpeg-dir \ --with-png-dir \ --with-zlib \ --with-libxml-dir \ --enable-xml \ --disable-rpath \ --enable-bcmath \ --enable-shmop \ --enable-sysvsem \ --enable-inline-optimization \ --with-curl \ --enable-mbregex \ --enable-mbstring \ --enable-intl \ --with-mcrypt \ --with-libmbfl \ --enable-ftp \ --with-gd \ --enable-gd-jis-conv \ --enable-gd-native-ttf \ --with-openssl \ --with-mhash \ --enable-pcntl \ --enable-sockets \ --with-xmlrpc \ --enable-zip \ --enable-soap \ --with-gettext \ --disable-fileinfo \ --enable-opcache \ --with-pear \ --enable-maintainer-zts \ --with-ldap=shared \ --without-gdbm \
开始安装
make -j 4 && make install
完成安装后配置php.ini文件：
cp php.ini-development /data/webserver/php/etc/php.ini cp /data/webserver/php/etc/php-fpm.conf.default /data/webserver/php/etc/php-fpm.conf cp /data/webserver/php/etc/php-fpm.d/www.conf.default /data/webserver/php/etc/php-fpm.d/www.conf
修改 php.ini 相关参数：
vim /data/webserver/php/etc/php.ini expose_php = Off short_open_tag = ON max_execution_time = 300 max_input_time = 300 memory_limit = 128M post_max_size = 32M date.timezone = Asia/Shanghai mbstring.func_overload=2
重启PHP，至此LNMP环境已搭建完成。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
How does session hijacking work and how can you mitigate it in PHP?
Apr 06, 2025 am 12:02 AM
Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

Describe the SOLID principles and how they apply to PHP development.
Apr 03, 2025 am 12:04 AM
The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
