简介
说实在的，作为一个人真的不应该图方便用安装脚本去安装lnmp环境的，因为这个环境的php等软件版本都把你固定死了，所以，现在我需要升级我的服务器上的php版本了，升级到什么版本呢？当然是最新版本
操作
首先你得确定你的php版本是什么版本
[root@vultr Ourls]# php -v
PHP 5.6.22 (cli) (built: Aug 25 2017 10:35:17)
Copyright (c) 1997-2016 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies
with Zend Guard Loader v3.3, Copyright (c) 1998-2014, by Zend Technologies
之后确定你要升级的php版本,比如我的是
wget http://php.net/distributions/php-5.6.31.tar.gz
5.6.31
解压
tar -zxvf php-5.6.31.tar.gz
之后查看一下你以前编译php所使用的编译参数
[root@vultr software]# php -i | grep configure
Configure Command => './configure' '--prefix=/usr/local/php' '--with-config-file-path=/usr/local/php/etc' '--enable-fpm' '--with-fpm-user=www' '--with-fpm-group=www' '--with-mysql=mysqlnd' '--with-mysqli=mysqlnd' '--with-pdo-mysql=mysqlnd' '--with-iconv-dir' '--with-freetype-dir=/usr/local/freetype' '--with-jpeg-dir' '--with-png-dir' '--with-zlib' '--with-libxml-dir=/usr' '--enable-xml' '--disable-rpath' '--enable-bcmath' '--enable-shmop' '--enable-sysvsem' '--enable-inline-optimization' '--with-curl' '--enable-mbregex' '--enable-mbstring' '--with-mcrypt' '--enable-ftp' '--with-gd' '--enable-gd-native-ttf' '--with-openssl' '--with-mhash' '--enable-pcntl' '--enable-sockets' '--with-xmlrpc' '--enable-zip' '--enable-soap' '--with-gettext' '--disable-fileinfo' '--enable-opcache' '--enable-intl' '--with-xsl'
记住，找个本子记下来
接着编译现在的php版本
把刚才的编译参数复制过去configure

成功
之后make
make
报错
/root/software/php-5.6.31/ext/xmlrpc/libxmlrpc/encodings.c:73: undefined reference to `libiconv_open'

make: *** [sapi/cli/php] 错误 1
安装libiconv
wget https://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.15.tar.gz
tar -zxvf libiconv-1.15.tar.gz
cd libiconv-1.15
./configure --prefix=/usr/local/libiconv
make
之后重新configure，注意加上libiconv的参数
'./configure' '--prefix=/usr/local/php' '--with-config-file-path=/usr/local/php/etc' '--enable-fpm' '--with-fpm-user=www' '--with-fpm-group=www' '--with-mysql=mysqlnd' '--with-mysqli=mysqlnd' '--with-pdo-mysql=mysqlnd' '--with-iconv-dir' '--with-freetype-dir=/usr/local/freetype' '--with-jpeg-dir' '--with-png-dir' '--with-zlib' '--with-libxml-dir=/usr' '--enable-xml' '--disable-rpath' '--enable-bcmath' '--enable-shmop' '--enable-sysvsem' '--enable-inline-optimization' '--with-curl' '--enable-mbregex' '--enable-mbstring' '--with-mcrypt' '--enable-ftp' '--with-gd' '--enable-gd-native-ttf' '--with-openssl' '--with-mhash' '--enable-pcntl' '--enable-sockets' '--with-xmlrpc' '--enable-zip' '--enable-soap' '--with-gettext' '--disable-fileinfo' '--enable-opcache' '--enable-intl' '--with-xsl' '--with-iconv=/usr/local/libiconv/'
接着stop php-fpm服务
sudo service php-fpm stop
之后
make
make install
查看版本
[root@vultr php-5.6.31]# php -v

启动php-fpm
sudo service php-fpm restart
注意
一定要备份好配置文件
