本篇文章介绍的是php版本切换的详细过程和线上Linux环境下常见php,在这里分享给大家,也给有需要的朋友做一下参考,大家一起来看一看吧

一、php版本切换

1)检测是否切换成功

判断是否切换成功的2个绝对正确的方法(推荐第一种):

1ps -ef|grep php

2、写个php文件 <?php echo phpinfo(); ?>


2)已有的版本切换

现有php7.0php7.1,目前在php7.0

==========1,亲测有效,start===================

brew services stop php70

ps -ef |grep php

brew services restart php@7.1

ps -ef |grep php

==========1end==========================


==========2start=========================

brew unlink php70

brew link php71

source ~/.bash_profile

php -v 此时显示的版本就是php7.1的了


解决: 按照提示操作即可

brew link php71 —force

echo 'export PATH="/usr/local/opt/php@7.1/bin:$PATH"' >> ~/.bash_profile

echo 'export PATH="/usr/local/opt/php@7.1/sbin:$PATH"' >> ~/.bash_profile

==========2start=========================


3)安装新的php版本,比如5.6,并切换到该版本

ps -ef|grep php //当前是一堆php@7.1的进程,需要杀死掉

brew services stop php@7.1

ps -ef|grep php //在查看,已经杀完了

brew install php56或者brew install php@5.6 //若报错,表示没此版本,不报错就已经在安装了

brew services restart php@5.6 //启用当前版本



4)两个重要文件

~/.bash_profile ==配置文件

~/.bash_aliases ==快捷键文件


~/.bash_aliases的文件的内容

alias nginx.start='launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.nginx.plist'

alias nginx.stop='launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.nginx.plist'

alias nginx.restart='nginx.stop && nginx.start'

alias php-fpm70.start="launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.php70.plist"

alias php-fpm70.stop="launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.php70.plist"

alias php-fpm70.restart='php-fpm70.stop && php-fpm70.start'

alias php-fpm71.start="launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.php71.plist"

alias php-fpm71.stop="launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.php71.plist"

alias php-fpm71.restart='php-fpm71.stop && php-fpm71.start'

alias mysql.start="launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist"

alias mysql.stop="launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist"

alias mysql.restart='mysql.stop && mysql.start'

分析:

快捷键

实际命令

nginx.start

launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.nginx.plist


二、线上Linux环境下常见php-fpm常见问题



解决:http://www.mamicode.com/info-detail-1157161.html



解决:1、Gracefully shutting down php-fpm warning, no pid file found - php-fpm is not running ?

关闭php-fpm服务时发现报错,缺乏pid文件,解决方法为编辑配置文件,启用pid文件:

vim /usr/local/php/etc/php-fpm.conf

pid = run/php-fpm.pid

2、ERROR : failed to open error_log……..

vim /usr/local/php/etc/php-fpm.conf

error_log = /usr/local/php/log/php-fpm.log

然后 cd /usr/local/php/ ,然后创建log文件夹,赋777权限,然后再到log文件夹里创建php-fpm.log文件




http://d-prototype.com/archives/6230

造成该问题的原因是:

路径【/usr/local/php-7.0.9/etc/php-fpm.d/】下没有找到【*.conf】的配置文件(config file)。

解决:cp www.conf.default www.conf




vim /usr/local/php/etc/php-fpm.d/www.conf




解决:打开php-fpm的配置文件

/usr/local/php/etc/php-fpm.d/www.conf

找到这2条并取消注释:

listen.allowed_clients = 127.0.0.1

listen = 127.0.0.1:9000

该解决方案将使您能够在您的虚拟主机块中使用listen = 127.0.0.1:9000

然后重启: service php-fpm restart
