Centos 7 smoothly and seamlessly upgrades PHP7.1.0 to PHP 7.1.5

Experimental environment: CentOS Linux release 7.3.1611 (Core)

Kernel version: Linux version 3.10.0-514.el7.x86_64

1. There are two ways to check the php version, and the display results are the same.

The first type

# /usr/local/php/bin/php -v

Second type

# php  -v

2. Before upgrading, you need to find the previous configure configuration module information and make sure it is consistent before and after the upgrade. Otherwise, normal access to the website may be affected. If you do not remember the previous configure information, you can write a phpinfo probe to find it, or Use the following command;

# php -i | grep configure

Configure Command => './configure' '--prefix=/usr/local/php' '--with-config-file-path=/usr/local/php/etc' '--with-fpm-user=www' '--with-fpm-group=www' '--with-iconv-dir' '--with-freetype-dir' '--with-jpeg-dir' '--with-png-dir' '--with-zlib' '--with-libxml-dir' '--enable-xml' '--disable-rpath' '--enable-bcmath' '--enable-shmop' '--enable-sysvsem' '--enable-inline-optimization' '--with-curl' '--enable-mbregex' '--enable-fpm' '--enable-mbstring' '--with-mcrypt' '--with-gd' '--enable-gd-jis-conv' '--enable-gd-native-ttf' '--with-openssl' '--with-mhash' '--enable-pcntl' '--enable-sockets' '--with-xmlrpc' '--enable-zip' '--enable-soap' '--enable-opcache' '--with-libmbfl' '--with-onig' '--enable-pdo' '--with-mysqli=mysqlnd' '--with-pdo-mysql=mysqlnd' '--with-pdo-mysql' '--enable-mysqlnd-compression-support' '--with-pear' '--enable-maintainer-zts' '--enable-session' '--with-gettext'

After slightly modifying the above information, you can install, configure and use it.

3. Important: Back up the old version of php first to prepare for quick rollback if the upgrade fails

 # mv /usr/local/php /usr/local/php7.1.bak
 # mkdir /renwole
 # cd /renwole
 # wget http://am1.php.net/distributions/php-7.1.5.tar.gz
 # tar zxvf php-7.1.5.tar.gz
 # cd php-7.1.5
 # ./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-fpm-user=www --with-fpm-group=www --with-iconv-dir --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-fpm --enable-mbstring --with-mcrypt --with-gd --enable-gd-jis-conv --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --enable-opcache --with-libmbfl --with-onig --enable-pdo --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-pdo-mysql --enable-mysqlnd-compression-support --with-pear --enable-maintainer-zts --enable-session --with-gettext

After PHP compilation is completed, you will see the words "Thank you for using PHP.", indicating that the compilation is complete, execute the following installation command;

# make && make install

This process is a bit slow, but it will not affect your normal access to the website, please be patient...

4.After php completes the upgrade installation configuration, start copying the php configuration file

# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
# cp /renwole/php-7.1.5/php.ini-development /usr/local/php/etc/php.ini
# cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf

或者沿用老版php配置文件（如果PHP版本跨度不大，建议使用老版本php.ini，否则php配置文件中的很多东西需要重新配置），\cp -rf表示覆盖无提示

# \cp -rf /usr/local/php7.1.0.bak/etc/php-fpm.conf /usr/local/php/etc/php-fpm.conf
# \cp -rf /usr/local/php7.1.0.bak/etc/php.ini /usr/local/php/etc/php.ini
# \cp -rf /usr/local/php7.1.0.bak/etc/php-fpm.d/www.conf /usr/local/php/etc/php-fpm.d/www.conf

5. Now restart php-fpm

# systemctl restart php-fpm.server

6. Check the php version again

# /usr/local/php/bin/php -v
