源码安装

  • 下载PHP72及解压源码包 PHP源码包地址
  • 安装前的准备 
    yum install -y gcc autoconf
yum install -y pcre pcre-devel
yum install -y zlib zlib-devel
yum install libxml2 libxml2-devel openssl openssl-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libmcrypt libmcrypt-devel -y
  • 执行./configure 命令 
    ./configure --prefix=/usr/local/php72 \
  --with-mysqli \
  --with-pdo-mysql \
  --with-jpeg-dir \
  --with-png-dir \
  --with-iconv-dir \
  --with-freetype-dir \
  --with-zlib \
  --with-libxml-dir \
  --with-gd \
  --with-openssl \
  --with-mhash \
  --with-curl \
  --with-pear \
  --with-fpm-user=nginx \
  --with-fpm-group=nginx \
  --enable-bcmath \
  --enable-soap \
  --enable-zip \
  --enable-fpm \
  --enable-mbstring \
  --enable-sockets \
  --enable-opcache \
  --enable-pcntl \
  --enable-simplexml \
  --enable-xml

    --with-fpm-user=nobody --with-fpm-group=nobody 设置为www用户也可以

  • 编译和安装 
    make && make install
  • 复制配置文件到php的配置目录 
    cp php.ini-development /usr/local/php72/lib/php.ini

    注意目录的对应,生产环境的为php.ini-production

安装扩展

  • 方式一: pecl安装扩展
# 要先安装pecl命令才能使用
yum install php-pear php-devel -y
# 如安装swoole扩展
pecl install swoole
  • 方式二: 源码安装
# 安装依赖工具
yum install gcc autoconf -y
# 如安装swoole扩展
yum install glibc-headers
yum install gcc-c++
curl -SL "https://github.com/swoole/swoole-src/archive/refs/tags/v4.8.0.tar.gz"  -o swoole.tar.gz \
  && mkdir -p swoole \
  && tar -xf swoole.tar.gz -C swoole --strip-components=1 \
  && cd swoole \
  && phpize && ./configure && make && make install

找到php.ini, 搜索";extension=",在最后一个被搜索到的地方添加extension=swoole.so，然后php -ir | grep swoole查看swoole信息

安装composer包管理工具

# 下载 https://github.com/composer/composer/releases
wget https://github.com/composer/composer/releases/download/2.0.12/composer.phar
wget https://getcomposer.org/download/2.0.12/composer.phar

# 放到用户bin目录
chmod u+x composer.phar && mv composer.phar /usr/local/bin/composer

自动重启

  • 启用进程id保存到文件 (/usr/local/php7/etc/php-fpm.conf => pid=run/php-fpm.pid)
  • 编写systemctl管理的配置文件 /usr/lib/systemd/system/php-fpm.service 
    [Unit]
Description=The PHP FastCGI Process Manager
After=system.target network.target

[Service]
Type=forking
PIDFile=/usr/local/php7/var/run/php-fpm.pid
ExecStartPre=/usr/bin/rm -f /usr/local/php7/var/run/php-fpm.pid
ExecStart=/usr/local/php7/sbin/php-fpm 
ExecReload=/bin/kill -USR2 $MAINPID
PrivateTmp=true

[Install]
WantedBy=multi-user.target
  • systemctl enable php-fpm.service (设置开机启动)
  • systemctl daemon-reload 重启服务
