How to compile and install php7.3

PHP 7.3 is the latest version of the PHP language. Compared with the old version, its performance and speed are better, and it also has thoughtful extension support. For best performance and security, we need to compile and install PHP 7.3 manually. Here are the specific steps and instructions.

1. Preparation before installation

Before starting the installation, please make sure that the following software packages have been installed on your system:

• GCC
• make
• autoconf
• libcurl4-openssl-dev
• libssl-dev
• libxml2-dev
• libmcrypt-dev
• libreadline-dev
• libpng-dev

2. Download and unzip the source code

Now we need to download the source code of PHP 7.3. You can download the source code package directly from the PHP official website, or you can use the following command:

wget https://www.php.net/distributions/php-7.3.30.tar.gz

After the download is completed, we need to decompress the source code package.

tar -zxvf php-7.3.30.tar.gz

3. Compile and install

After decompressing, go to the directory and run the following command to manually compile PHP 7.3:

cd php-7.3.30
./configure --prefix=/usr/local/php7 \
--with-config-file-path=/usr/local/php7/etc \
--enable-fpm \
--with-fpm-user=www-data \
--with-fpm-group=www-data \
--with-mysqli=mysqlnd \
--with-pdo-mysql=mysqlnd \
--with-iconv-dir \
--with-freetype-dir \
--with-jpeg-dir \
--with-png-dir \
--with-zlib \
--with-libxml \
--with-curl \
--with-gd \
--with-mcrypt \
--with-openssl \
--enable-mbstring \
--enable-soap \
--enable-sockets \
--disable-ipv6 \
--disable-debug \
--enable-opcache \
--enable-xml \
--enable-zip \
--enable-bcmath \
--enable-calendar \
--enable-exif \
--enable-ftp \
--enable-gd-native-ttf \
--enable-maintainer-zts \
--enable-pcntl \
--enable-shmop \
--enable-sysvmsg \
--enable-sysvsem \
--enable-sysvshm \
--with-readline \
--with-pear

Note that you need to make appropriate adjustments based on your system configuration. Adjustment.

After successful execution, run the following command to install PHP 7.3 into the system:

make
sudo make install

Now, PHP 7.3 has been installed successfully!

4. Configure PHP 7.3

In order for the system to use PHP 7.3 normally, we need to perform some configurations. In the previous step, we have installed PHP into the /usr/local/php7 directory, now we need to create a php.ini configuration file:

sudo mkdir /usr/local/php7/etc
sudo cp php.ini-development /usr/local/php7/etc/php.ini
sudo cp /usr/local/php7/etc/php-fpm.conf.default /usr/local/php7/etc/php-fpm.conf

5. Start and stop PHP FPM

PHP FPM is the FastCGI process manager for PHP. After installing PHP, we need to start it manually:

sudo /usr/local/php7/sbin/php-fpm

We can also stop PHP FPM through the following command:

sudo /usr/local/php7/sbin/php-fpm -s stop
