虽然之前写过很多编译安装PHP的文章， 但是隔段时间还是会重新安装一些PHP的版本，再次记录一下
1. 下载安装编译工具
yum groupinstall 'Development Tools'
2.安装依赖包
yum install libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel ncurses curl gdbm-devel db4-devel libXpm-devel libX11-devel gd-devel gmp-devel expat-devel xmlrpc-c xmlrpc-c-devel libicu-devel libmcrypt-devel libmemcached-devel
3. 下载并解压PHP7.4
wget http://mirrors.sohu.com/php/php-7.4.0.tar.gz
# 解压
tar -zxvf php-7.4.0.tar.gz
cd php-7.4.0
4. 新增用户和用户组
groupadd www
useradd -g www www
5. 生成编译文件
./configure \
--prefix=/usr/local/php \
--with-config-file-path=/etc \
--with-fpm-user=www \
--with-fpm-group=www \
--with-curl \
--with-freetype-dir \
--enable-gd \
--with-gettext \
--with-iconv-dir \
--with-kerberos \
--with-libdir=lib64 \
--with-libxml-dir \
--with-mysqli \
--with-openssl \
--with-pcre-regex \
--with-pdo-mysql \
--with-pdo-sqlite \
--with-pear \
--with-png-dir \
--with-jpeg-dir \
--with-xmlrpc \
--with-xsl \
--with-zlib \
--with-bz2 \
--with-mhash \
--enable-fpm \
--enable-bcmath \
--enable-libxml \
--enable-inline-optimization \
--enable-mbregex \
--enable-mbstring \
--enable-opcache \
--enable-pcntl \
--enable-shmop \
--enable-soap \
--enable-sockets \
--enable-sysvsem \
--enable-sysvshm \
--enable-xml \
--with-zip \
--enable-fpm
注意：有些编译项需要进行修改可以通过./configure --help 查看具体的项
./configure --prefix=/usr/local/php7 --with-config-file-path=/usr/local/php7/etc --with-fpm-user=www --with-fpm-group=www --with-curl --with-freetype-dir --with-gd --with-gettext --with-iconv-dir --with-kerberos --with-libdir=lib64 --with-libxml-dir --with-mysqli --with-openssl --with-pcre-regex --with-pdo-mysql --with-pdo-sqlite --with-pear --with-png-dir --with-jpeg-dir --with-xmlrpc --with-xsl --with-zlib --with-bz2 --with-mhash --enable-fpm --enable-bcmath --enable-libxml --enable-inline-optimization --enable-mbregex --enable-mbstring --enable-opcache --enable-pcntl --enable-shmop --enable-soap --enable-sockets --enable-sysvsem --enable-sysvshm --enable-xml --enable-zip --enable-fpm
6. 编译安装
make && make install -j 2
-j 指定执行的进程数
7.安装成功之后，设置环境变量
vim /etc/profile
添加
PATH=$PATH:/usr/lcoal/php74/bin
export PATH
立即生效
source /etc/profile
8. 测试查看PHP版本
php -v
创建php-fpm软链接
ln -s /usr/local/php74/sbin/php-fpm /usr/local/php74/bin/php-fpm
php-fpm -v
9.配置
#将源码中的配置文件复制到PHP的配置文件中
cp php.ini-production /usr/local/php74/etc/php.ini
#将PHP目录中的php-fpm配置文件进行修改
cp php-fpm.conf.default php-fpm.conf
cp php-fpm.d/www.conf.default php-fpm.d/www.conf
10.添加php-fpm启动项
#将PHP源码中的php-fpm启动文件加入到服务自启动文件中
cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
#赋予执行权限
chmod +x /etc/init.d/php-fpm
#启动php-fpm
/etc/init.d/php-fpm start
11.php-fpm服务化
centos7 已经使用systemctl来进行服务的管理，这里我们也使用systemctl来对php-fpm进行管理
修改php-fpm.conf文件
打开pid=/var/run/php-fpm.pid
cp sapi/fpm/php-fpm.service /usr/lib/systemd/system/php-fpm74.service
ln -s /usr/lib/systemd/system/php-fpm74.service /usr/lib/systemd/system/php-fpm.service
systemctl daemon-reload
systemctl enable php-fpm
php-fpm.service文件内容：
[Unit]
Description=The PHP FastCGI Process Manager
After=network.target
[Service]
Type=simple
PIDFile=/usr/local/php74/var/run/php-fpm.pid
ExecStart=/usr/local/php74/sbin/php-fpm --nodaemonize --fpm-config /usr/local/php74/etc/php-fpm.conf
ExecReload=/bin/kill -USR2 $MAINPID
PrivateTmp=true
[Install]
WantedBy=multi-user.target
停止之前启动的php-fpm， 使用systemctl启动php-fpm
systemctl start php-fpm.service
12.在使用的时候发现zip扩展没有安装，现在需要添加扩展
在PHP源代码包中，我的源码路径：/opt/php-7.4.0/， 需要进去到zip扩展包中cd /opt/php-7.4.0/ext/zip
#生成配置文件
phpize
./configure --with-php-config=/usr/local/php74/bin/php-config --with-zip
make && make install
在配置文件中开启扩展即可 php.ini
常见错误：
1. error： Package requirements (sqlite3 > 3.7.4) were not met
yum install libsqlite3x-devel -y
2.error: Package requirements (oniguruma) were not met
yum install oniguruma-devel -y
3. 访问nginx无法解析PHP文件
server {
listen 8081;
server_name localhost;
index index.html index.php;
root /data/www;
access_log /data/logs/www.access.log main;
error_log /data/logs/www.error.log;
location / {
if (!-e $request_filename) {
rewrite ^/(.*) /index.php last;
}
}
location ~ .*\.(php|php5)$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; # 这里注意需要进行修改
include fastcgi_params;
}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}3. configure: error: Package requirements (libzip >= 0.11) were not met: No package 'libzip'
libzip 版本太低了
编译安装，指定PKG_CONFIG_PATH，上面报错中其实有提示信息，让我们考虑调整PKG_CONFIG_PATH环境变量。
下面是详细步骤：
# 先卸载已有
yum remove libzip
# 然后安装
wget https://libzip.org/download/libzip-1.2.0.tar.gz
tar -zxvf libzip-1.2.0.tar.gz
cd libzip-1.2.0
./configure
make && make install
装完了之后找一下/usr/local/lib下有没有pkgconfig目录，有的话执行命令export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig/"指定PKG_CONFIG_PATH。
到这里问题解决！
4. 安装扩展的时候，
Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONF environment
安装autoconf
yum install -y autoconf
