LAMP is a very popular web development environment at the moment. Many developers will encounter various problems in the process of building LAMP. Thinking of these problems, their heads are about to explode. Today, I specially took the time to record the process of building a PHP development environment for everyone's reference. If you find any problems, I hope you can correct them.
1. Obtain the installation package
2. Install Apache
1. Dependencies Package installation
1) Install compiler gcc, gcc-c
yum install -y gcc gcc-c++2) Install dependency packages expat-devel, zlib-devel, openssl-devel
yum install -y expat-devel zlib-devel openssl-devel2) Install dependency package apr
wget http://mirror.bit.edu.cn/apache//apr/apr-1.6.2.tar.gz tar zxvf apr-1.6.2.tar.gz cd apr-1.6.2 ./configure --prefix=/usr/local/apr make && make install3) Install dependency package apr-util
wget http://mirror.bit.edu.cn/apache//apr/apr-util-1.6.0.tar.gz tar zxvf apr-util-1.6.0.tar.gz cd apr-util-1.6.0 ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr make && make install4) Install dependency package pcre
wget https://ftp.pcre.org/pub/pcre/pcre-8.41.tar.gz tar zxvf pcre-8.41.tar.gz cd pcre-8.41 ./configure --prefix=/usr/local/pcre make && make installNote: Copy the apr and apr-util installation packages to the srclib directory of the Apache installation package
Name them apr, apr-util respectively, without the subsequent version number
2. Installation process
1) Unzip the Apache installation package
tar zxvf httpd-2.4.28.tar.gz2) Compile and install
cd httpd-2.4.28 ./configure --prefix=/usr/local/server/apache \ --with-apr=/usr/local/apr \ --with-apr-util=/usr/local/apr-util \ --with-pcre=/usr/local/pcre \ --enable-so \ --enable-ssl \ --enable-deflate \ --enable-rewrite \ --enable-headers \ --enable-expires \ --disable-cgid\ --disable-cgi make && make install
3. Modify the configuration file httpd.conf
vim /usr/local/server/apache/conf/httpd.confRemove
# in front of ServerName and change the URL after ServerName to localhost:80
4. Add httpd to the system service and set it to start automatically at boot
1) Add httpd to the system service
cp /usr/local/server/apache/bin/apachectl /etc/init.d/httpd2) Modify /etc/init.d/httpd and add the following content to line 3
# chkconfig: 345 85 15 # description: Activates/Deactivates Apache Web ServerNote: The # in the code cannot be removed
3) Set the system service to start automatically at boot
systemctl enable httpd4) Start Apache
service httpd start
3. Install MySQL
1. Preparation before installation
1) Unzip the installation package
tar zxvf mysql-5.7.19-linux-glibc2.12-x86_64.tar.gz mv mysql-5.7.19-linux-glibc2.12-x86_64 /usr/local/server/mysql2) Create users and user groups and assign corresponding permissions
groupadd mysql useradd -r -g mysql mysql -s /sbin/nologin3) Install dependencies
yum -y install numactl.x86_64
2. Initialize mysql and make basic configuration
1) Initialize mysql
cd /usr/local/server/mysql bin/mysqld \ --initialize \ --user=mysql \ --basedir=/usr/local/server/mysql \ --datadir=/usr/local/server/mysql/data \2) Configure mysql
vim my.cnf # 创建配置文件This example only ensures that mysql can run normally. For more configuration, please refer to the official documentation
[mysqld] skip-grant-tables basedir = /usr/local/server/mysql datadir = /usr/local/server/mysql/data socket = /usr/local/server/mysql/data/mysql.sock log-error = /usr/local/server/mysql/log/error.log port = 3306 [mysql_safe] pid-file = /var/run/mysql/mysqld.pid log-error = /usr/local/server/mysql/log/error.log [client] port = 3306 socket = /usr/local/server/mysql/data/mysql.sockSoft link the configuration file to the /etc/ directory
ln -s /usr/local/server/mysql/my.cnf /etc/my.cnfNote: If you are prompted that the file exists when creating a soft link, you can delete /etc/my.cnf and then create a soft link
3) Create a database to store information Required Directories and Files
mkdir /usr/local/server/mysql/data mkdir /usr/local/server/mysql/log mkdir /var/run/mysql touch /usr/local/server/mysql/log/error.log4) Set directory owner
chown -R mysql:mysql /usr/local/server/mysql/ chown -R mysql:mysql /var/run/mysql/
3. Set environment variables and auto-start at boot
1) Set environment variables
Edit profile file
vim /etc/profileAdd the following information to the end of profile
export PATH=$PATH:/usr/local/server/mysql/binMake environment variables take effect immediately
source /etc/profile2) Set up auto-start at boot
cp support-files/mysql.server /etc/init.d/mysqld chkconfig --add mysqld chkconfig mysqld on
4. Firewall settings
CentOS has the firewall enabled by default. Below we use firewall to open the 3306l port
1) Before we enable it First check whether port 3306 is open
firewall-cmd --query-port=3306/tcp2) If it is not turned on, turn on the firewall firewall
systemctl start firewalld.service3) We can choose to temporarily open or permanently open port 3306
firewall-cmd --add-port=3306/tcp # 临时开启3306端口 firewall-cmd --permanent --zone=public --add-port=3306/tcp # 永久开启3306端口4) Restart firewall
firewall-cmd --reload
5. Start mysql and set the root user password
1) Start mysql
/usr/local/server/mysql/support-files/mysql.server start # 启动MySQL /usr/local/server/mysql/bin/mysql -uroot -p # 这里直接回车,无须输入密码2) Set root user password
use mysql; update user set authentication_string=password('root') where user='root'; exit;Note 1: After successfully changing the password, log out of skip-grant-tables in the configuration file
Restart mysql and log in again using the root user, and then execute the following code
set password=password('root');Note 2: It is a system requirement to reset the password for the second time, otherwise the database cannot be operated
6. Remote access
1) Give access to any host mysql permissions
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'your password' WITH GRANT OPTION;2) Make permission modification take effect
FLUSH PRIVILEGES;
4. Install PHP
1. Installation steps
1) Install the dependency package libxml-devel
yum -y install libxml2-devel2) Unzip the PHP installation package
tar zxvf php-7.1.10.tar.gz3) Compile and install
cd php-7.1.10 ./configure --prefix=/usr/local/server/php \ --with-apxs2=/usr/local/server/apache/bin/apxs \ --with-config-file-path=/usr/local/server/php \ --with-pdo-mysql make && make install
2. Configure php.ini
1) Copy the configuration file to the PHP installation directory
cp php.ini-* /usr/local/server/php/2) Generate php.ini
cp php.ini-development /usr/local/server/php/php.ini
3. Modify httpd.conf
载入PHP模块,如httpd.conf中有下列代码则直接去掉前面#即可,没有则加入
LoadModule php7_module modules/libphp7.so在底部加入以下代码使得Apache可以解析php文件
<IfModule mod_php7.c> AddType application/x-httpd-php .php </IfModule>找到如下代码,在index.html后面加入index.php
<IfModule dir_module> DirectoryIndex index.html </IfModule>重启Apache
service httpd restart
4. 测试PHP是否成功安装
创建/usr/local/server/apache/htdocs/index.php
vim /usr/local/server/apache/htdocs/index.php在index.php中编写以下代码
<?php phpinfo(); ?>如果出现以下页面则安装成功
