lnmp 多個php版本共存

lnmp 多個php版本共存

本例(ubuntu系統)已經過lnmp安裝好php7.1了，因此後面手動安裝php5.6.36。可是爲何須要安裝多個版本的PHP？發揮你的小宇宙想象一下吧。

安裝PHP5.6.36

下載php5.6.36

wget http://cn.php.net/distributions/php-5.6.36.tar.gz

解壓

tar zxvf ./php-5.6.36.tar.gz

配置

./configure \
--prefix=/usr/local/php56 \
--with-config-file-path=/usr/local/php56/etc \
--with-config-file-scan-dir=/usr/local/php56/conf.d \
--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

若是過程提示錯誤好比：freetype，就解決這些錯誤再從新執行配置

先搜索這個名字，看看安裝包的具體名字是什麼，而後再使用apt-get安裝

apt-cache search freetype

apt-get install libfreetype6-dev

執行make

make

我出現了這種錯誤，recipe for target 'sapi/cli/php' failed，解決方法是直接編輯makefile文件，搜索EXTRA_LIBS，在EXTRA_LIBS= 後面添加-liconv，如：EXTRA_LIBS = ..... -lcrypt -liconv，而後執行make clean，再執行一次make。
最後就是make install了

make install

配置php5.6

cp /root/php-5.6.36/php.ini-development /usr/local/php56/etc/php.ini

打開並修改/usr/local/php56/etc/php.ini
查找 mysql.default_socket 改爲

mysql.default_socket = /tmp/mysql.sock

查找 mysqli.default_socket 改爲

mysqli.default_socket = /tmp/mysql.sock

查看php5.6版本

/usr/local/php56/bin/php -v

配置 php-fpm 服務

由於 PHP 7 的服務文件爲 php-fpm.service 因此這裏用 php56-fpm.service

cp sapi/fpm/php-fpm.service /usr/lib/systemd/system/php56-fpm.service

編輯php56-fpm.service，修改

PIDFile=${prefix}/var/run/php-fpm.pid
ExecStart=${exec_prefix}/sbin/php-fpm --nodaemonize --fpm-config ${prefix}/etc/php-fpm.conf

爲

PIDFile=/usr/local/php56/var/run/php-fpm.pid
ExecStart=/usr/local/php56/sbin/php-fpm --nodaemonize --fpm-config /usr/local/php56/etc/php-fpm.conf

在/usr/local/php56/etc下添加文件php-fpm.conf
內容爲

[global]
pid = /usr/local/php56/var/run/php-fpm.pid
error_log = /usr/local/php56/var/log/php-fpm.log
log_level = notice

[www]
listen = /tmp/php56-cgi.sock
listen.backlog = -1
listen.allowed_clients = 127.0.0.1:9001
listen.owner = www
listen.group = www
listen.mode = 0666
user = www
group = www
pm = dynamic
pm.max_children = 20
pm.start_servers = 10
pm.min_spare_servers = 10
pm.max_spare_servers = 20
request_terminate_timeout = 100
request_slowlog_timeout = 0
slowlog = var/log/slow.log

在/usr/local/php56/var/run中添加一個文件php-fpm.pid，內容爲

3353

由於php7的pid爲3352，因此這裏用3353，這個隨意，不要和別的軟件衝突就行。

從新載入 systemd

systemctl daemon-reload

能夠設置開機啓動：

systemctl enable php56-fpm

當即啓動 php-fpm

systemctl start php56-fpm

查看php5.6的狀態

systemctl status php56-fpm

配置不一樣的 nginx 站點使用不用的 PHP 版本

在/usr/local/nginx/conf下添加一個文件名爲enable-php56.conf
內容爲

location ~ [^/]\.php(/|$)
    {
        try_files $uri =404;
        fastcgi_pass  unix:/tmp/php56-cgi.sock;
        fastcgi_index index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include fastcgi_params;
    }

修改域名配置文件中的include enable-php.conf;爲include enable-php56.conf;

server
    {
        listen 80;
        ...
        include enable-php56.conf;
        ...
    }

測試一下

在各域名目錄下添加一個info.php文件測試一下

<?php
phpinfo();
?>
