⑴ linux系统下怎么搭建网站服务器
具体方法如下:
1、使用putty或类似的SSH工具登录服务器(本地安装跳过);
⑵ linux yum安装php7.3
先安装前面的教程,再安装后面的

安装PHP
1、安装PHP73
1.1、卸载旧版本PHP
yum remove php*
1.2、安装EPEL:
sudo yum install epel-release
1.3、安装remi(选一个):
sudo rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
1.4、查看目前有php的什么版本(可忽略)
sudo yum list php*
1.5、列出所有的php相关的rpm包(可忽略)
rpm -qa|grep php
1.6、删除php相关的rpm包(一次只能删除一个)(可忽略)
rpm -e php72w-mysqlnd-7.2.17-1.w7.x86_64
1.7、列出remi仓库下所有PHP7.3可用模块。(可忽略)
yum --enablerepo=remi-php73 search php | grep php73
1.8、安装PHP 7.3
yum --enablerepo=remi-php73 install php
1、安装 PHP7.3:
(解决yum安装apache关联不了PHP的问题,用以下命令安装)
yum --enablerepo=remi-php73 install php
安装模块
yum --enablerepo=remi-php73 install php73-php-fpm php73-php-cli php73-php-bcmath php73-php-gd php73-php-json php73-php-mbstring php73-php-mcrypt php73-php-mysqlnd php73-php-opcache php73-php-pdo php73-php-pecl-crypto php73-php-pecl-mcrypt php73-php-pecl-geoip php73-php-recode php73-php-snmp php73-php-soap php73-php-xml
2、设置开机启动、运行服务:
systemctl enable php73-php-fpm
systemctl start php73-php-fpm
3、查找php.ini位置:
find /etc/opt/remi/php73 -name php.ini
/etc/opt/remi/php73/php.ini
找到apache的配置文件:httpd.conf
sudo find / -name httpd.conf
位置如下:
/etc/httpd/conf/httpd.conf
5、PHP日常操作
systemctl restart php73-php-fpm #重启
systemctl start php73-php-fpm #启动
systemctl stop php73-php-fpm #关闭
systemctl status php73-php-fpm #检查状态
php -m #查看PHP已安装拓展模块
php -v #查看PHP版本
⑶ 如何在linux下安装多个不同版本的PHP
Linux下部署php多版本共存
背景说明
自php7问世,身为最新版本控的我马上升级体验,但是由于服务器上还有旧程序在运行,只好部署一个php多版本共存环境。
现有环境是lnmp
- CentOS 6.7
- nginx 1.10.1
- mariadb-10.0.26
- php 7.0.8
为了更好兼容旧的php程序,推荐使用5.4.45. 主要是兼容mysql扩展。
开始安装
首先要下载php-5.4.45.tar.gz源码包。
通过源码安装
# tar xzvf php-5.4.45.tar.gz
# cd php-5.4.45
# ./configure --prefix=/usr/local/php54 --with-config-file-path=/usr/local/php54/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-intl --with-xsl
# make ZEND_EXTRA_LIBS='-liconv'
# make install
# cp php.ini-proction /usr/local/php/etc/php.ini
------------------------------------------------------------------------------------------------
php.ini 配置
post_max_size = 50M
upload_max_filesize = 50M
date.timezone = PRC
short_open_tag = On
cgi.fix_pathinfo=0
max_execution_time = 300
disable_functions=passthru,exec,system,chroot,scandir,chgrp,chown,shell_exec,proc_open,proc_get_status,popen,ini_alter,ini_restore,dl,openlog,syslog,readlink,symlink,popepassthru,stream_socket_server
------------------------------------------------------------------------------------------------
php-fpm.conf 配置
------------------------------
# vim /usr/local/php/etc/php-fpm.conf1
[global]
pid = /usr/local/php54/var/run/php-fpm.pid
error_log = /usr/local/php54/var/log/php-fpm.log
log_level = notice
[www]
listen = /tmp/php54-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 = 40
pm.start_servers = 20
pm.min_spare_servers = 20
pm.max_spare_servers = 40
request_terminate_timeout = 100
request_slowlog_timeout = 0
slowlog = var/log/slow.log
----------------------------------------------------------------------------------
启动 php-fpm
# cp sapi/fpm/init.d.php-fpm /etc/init.d/php54-fpm
# chmod +x /etc/init.d/php54-fpm
# /etc/init.d/php54-fpm start
-------------------------------------------------------------------------------------------
修改nginx配置,对需要的服务配置使用php-5.4.45
location ~ [^/]\.php(/|$)
{
try_files $uri =404;
fastcgi_pass unix:/tmp/php54-cgi.sock;
fastcgi_index index.php;
include fastcgi.conf;
}
----------------------------------------------------------------------------------------
配置php-5.4.45 的php54-fpm 开机自动启动
# chkconfig --add php54-fpm
# chkconfig php54-fpm on
