wordpress轻量应用服务器升级php版本

注意事项

• 建议使用默认的环境操作
• Wordpress镜像用的是4.8.1这个版本

安装依赖

yum install -y libxml2-devel openssl-devel curl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel xslt libxslt-devel yum update -y curl curl-devel yum remove -y libzip

配置SWAP

如果内存是低于1GB的，则需要配置一下swap，编译过程需要依赖更多内存，内存太低会报错

dd if=/dev/zero of=/swap bs=1M count=2048 mkswap -f /swap swapon /swap

安装libzip

PHP7.3要求libzip版本大于0.11，但yum安装版本达不到要求，所以这里手动编译一下，该项不满足报错对应如下：
checking for libzip... configure: error: system libzip must be upgraded to version >= 0.11

wget https://nih.at/libzip/libzip-1.2.0.tar.gz tar -zxvf libzip-1.2.0.tar.gz cd libzip-1.2.0 ./configure make && make install

编译好后还需要做一下软连接，否则会提示报错找不到zipconf.h文件

ln -s /usr/local/lib/libzip/include/zipconf.h /usr/local/include

编译安装PHP

wget https://www.php.net/distributions/php-7.3.9.tar.gz tar -xvf php-7.3.9.tar.gz cd php-7.3.9 ./configure --prefix=/usr/local/php73 --enable-soap --enable-cgi --with-mysql=/usr/local/mysql --with-mysqli=mysqlnd --with-gd --with-pdo-mysql=mysqlnd --with-zlib --enable-zip --enable-fpm --without-pear --disable-phar --with-openssl --enable-mbstring=all --with-jpeg-dir=/usr --with-png-dir=/usr --with-curl --with-freetype-dir=/usr --enable-gd-native-ttf --with-xsl=/usr --enable-calendar --enable-exif --enable-ftp --with-iconv --enable-bcmath --with-mcrypt=/usr/local/libmcrypt --enable-opcache make && make install

这个编译过程会比较长，编译完成后修改一下配置文件

# 将启动脚本复制到init.d中，${PHP73}对应是源码解压的目录 cp ${PHP73}/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm73 # 给启动脚本加上执行权限 chmod +x /etc/init.d/php-fpm73 # 将默认配置文件复制为.conf文件 cp /usr/local/php73/etc/php-fpm.conf.default ${PHP73_DIR}/etc/php-fpm.conf # 添加pool的配置 cat << EOF > /usr/local/php73/etc/php-fpm.d/www.conf [www] listen = /home/www/logs/php73-fpm.sock listen.mode = 0666 user = www group = www pm = dynamic pm.max_children = 128 pm.start_servers = 5 pm.min_spare_servers = 5 pm.max_spare_servers = 15 pm.max_requests = 300 rlimit_files = 1024 slowlog = /home/www/logs/php73-fpm-slow.log EOF

至此PHP已经编译配置完成，接下来需要修改apache使用新版的php

修改apache

镜像中默认是用的php-fpm，使用的是socket方式的监听，Apache对应配置文件/usr/local/apache/conf/httpd.conf,可以看到其中配置如下

我们只需要修改其中socket的文件路径指向到新版本的PHP就可以了，在/usr/local/php73/etc/php-fpm.d/www.conf有指定，新的配置到/home/www/logs/php73-fpm.sock即可，如图

重启服务

# 停止旧版本的PHP(实际不停止也不影响，停止可以减少一些系统资源占用) /etc/init.d/php-fpm stop # 启动新版PHP-FPM /etc/init.d/php-fpm73 start # 重启apache /etc/init.d/apachectl restart

验证

站点根目录是/home/www/htdocs/，放入phpinfo探针即可检测PHP版本

至此轻量应用服务器wordpress镜像更新PHP版本操作已完成，可以愉快的更新wordpress到新版本了。为了操作更简单，这里总结成了一个脚本，可以复制到主机内一键执行
