centos源码安装php

A. centos 如何检测php安装

需要准备的材料分别是：电脑、centos主机，linux连接工具。

1、首先连接上centos主机，进入等待输入指令的linux命令行状态。

B. centos下安装php

yum install -y php
## 这个只安装PHP
## 建议安装运行库及Mysql的支持
yum install -y php php-devel php-mysql
## 如果你的系统是CentOS 5.6那么上面这条命令安装的是PHP 5.1,要安装 PHP 5.3则执行下面的命令:
yum install -y php53 php53-devel php53-mysql

C. 我的vps已安装了centos-7.6-x86_64，怎样安装php扩展

为了让网站成功运行，就需要在php中增加bcmath这个扩展（其实默认的php中已经存在bcmath扩展，但是没有安装编译）
安装php的扩展bcmath具体步骤如下（以下操作均在wdcp 2.4的环境中）：
1、ssh登陆vps控制台后，进入要安装的扩展的源码目录:cd /root/lanmp/php-5.2.17/ext/bcmath
2、运行phpize，这是wdcp中的路径: /www/wdlinux/php/bin/phpize
出现如下提示:
configuring for:
php api version:
20041225
zend mole api no: 20060613
zend extension api no: 220060519
3、编译安装：
./configure --with-php-config=/www/wdlinux/php/bin/php-config
make
make install
4、增加到配置文件php.ini里
vi /www/wdlinux/etc/php.ini
在最后增加：extension=bcmath.so
5、重启服务
service httpd restart
service nginxd restart
然后就大功告成

D. centos编译安装php7怎么加入apache

直接下载PHP7.0.2的安装包解压，编译，安装:
下载php7,并解压
$ cd /usr/src/
$ wget http://cn2.php.net/distributions/php-7.0.2.tar.gz
#解压
$ tar -xzxvf php-7.0.2.tar.gz
$ cd php-7.0.2
解压完后先不要编译，请检查是否安装了gcc ,没有的话执行yum install gcc
检查是否安装了libxml2 ,没有的话执行yum install libxml2
检查是否安装了libxml2-devel,没有的话执行yum install libxml2-devel
注：因为改为用nginx了，所以编译参数中的--with-apxs2=/usr/bin/apxs去掉了，如果要配置apache用，安装PHP前，请先安装apache。

E. centos6.5怎么安装php5.5

1.******已安装Nginx******
ps -aux | grep nginx
netstat -anptu | grep 80

2.清除系统中php痕迹：
yum remove php
rm -rvf /etc/php
rm -rvf /etc/php.ini
rm -f /usr/bin/php

3.安装php所需软件包：
tar zxvf autoconf-2.68.tar.gz -C /usr/src
cd /usr/src/autoconf-2.68/
./configure && make && make install
tar zxvf libiconv-1.14.tar.gz -C /usr/src
cd /usr/src/libiconv-1.14/
./configure && make && make install
tar zxvf libmcrypt-2.5.8.tar.gz -C /usr/src
cd /usr/src/libmcrypt-2.5.8/
./configure && make && make install
ldconfig
cd libltdl/
./configure --enable-ltdl-install
make && make install
export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
tar zxvf mhash-0.9.9.9.tar.gz -C /usr/src
cd /usr/src/mhash-0.9.9.9/
./configure && make && make install
tar zxvf mcrypt-2.6.8.tar.gz -C /usr/src
cd /usr/src/mcrypt-2.6.8/
./configure && make && make install

4.加载php动态模块：
ln -s /usr/local/lib/libmcrypt.la /usr/lib64/libmcrypt.la
ln -s /usr/local/lib/libmcrypt.so /usr/lib64/libmcrypt.so
ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib64/libmcrypt.so.4
ln -s /usr/local/lib/libmcrypt.so.4.4.8
/usr/lib64/libmcrypt.so.4.4.8

ln -s /usr/local/lib/libmhash.so.2 /usr/lib64/libmhash.so.2
ln -s /usr/local/lib/libmhash.so.2.0.1
/usr/lib64/libmhash.so.2.0.1
cp -R /usr/lib64/libpng.* /usr/lib/
cp -R /usr/lib64/libjpeg.* /usr/lib/
echo "/lib" >> /etc/ld.so.conf
echo "/usr/lib" >> /etc/ld.so.conf
echo "/usr/lib64" >> /etc/ld.so.conf
echo "/usr/local/lib" >> /etc/ld.so.conf
echo "* soft nproc 65535" >> /etc/security/limits.conf

echo "* hard nofile 65535" >> /etc/security/limits.conf
echo "fs.file-max=65535" >> /etc/sysctl.conf

ldconfig

5.解压、配置、编译、安装php：
tar zxvf php-5.5.25.tar.gz -C /usr/src
cd /usr/src/php-5.5.25/
./configure --prefix=/usr/local/php \

10.创建目录并修改权限，重启nginx服务：
mkdir -p /home/php/log
mkdir -p /home/php/pid
chown -R www:www /home/php/log
chown -R www:www /home/php/pid
service nginx restart

11.添加php-fpm系统服务：
chmod +x /etc/init.d/php-fpm
chkconfig --add php-fpm
chkconfig --level 2345 php-fpm on
chkconfig --list | grep php-fpm

12.启动php-fpm服务：
service php-fpm start
ps -aux | grep php-fpm
netstat -anptu | grep 9000

13.配置php测试页：
vim /home/www/html/phpinfo.php

F. 如何在centos7上安装php

您好，安装PHP的方式可以一步一步的按照教程去安装，这个可以到网上搜一搜，因为步骤太多，我就不复制粘贴了。但是我这里最推荐的就是使用phpstudy一键安装，没错，就是在Linux上一键安装，可以去试一试。

黑马程序员的PHP是国内最早开设的真正人工智能课程。课程全面系统，紧跟时代潮流。

G. 阿里云默认centos7上怎么安装php

首先更新系统软件</str>
$ yum update
安装nginx</str></str>
1.安装nginx源
$ yum localinstall http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm2.安装nginx
$ yum install nginx
3.启动nginx
$ service nginx start
Redirecting to /bin/systemctl start nginx.service4.访问http://你的ip/
如果成功安装会出来nginx默认的欢迎界面
安装MySQL5.7.*
</str>
1.安装mysql源</str>
$ yum localinstall http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm2.安装mysql
$ yum install mysql-community-server
确认一下mysql的版本，有时可能会提示mysql5.63.安装mysql的开发包，以后会有用
$ yum install mysql-community-devel
4.启动mysql
$ service mysqld start
Redirecting to /bin/systemctl start mysqld.service5.查看mysql启动状态
$ service mysqld status
出现pid
证明启动成功
6.获取mysql默认生成的密码
$ grep 'temporary password' /var/log/mysqld.log2015-12-05T05:41:09.104758Z 1 [Note] A temporary password is generated for root@localhost: %G1Rgns!dD!v</str>
加粗的就是生成的密码
7.换成自己的密码
$ mysql -uroot -p
Enter password:输入上面的密码
成功输入后进入一下步，这里你估计会输入 好几次才进去8. 更换密码
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!';这个密码一定要足够复杂，不然会不让你改，提示密码不合法;9.退出mysql;
mysql> quit;
10.用新密码再登录，试一下新密码
$ mysql -uroot -p
Enter password:输入你的新密码
11.确认密码正确后，退出mysql;
mysql> quit;
编译安装php7.0.0
</str>
</str>
1.下载php7源码包</str>
$ cd /root & wget -O php7.tar.gz http://cn2.php.net/get/php-7.0.1.tar.gz/from/this/mirror2.解压源码包</str>
$ tar -xvf php7.tar.gz
3.</str>
$ cd php-7.0.1
4.安装php依赖包</str>
</str>
$ yum install libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel5.编译配置，这一步我们会遇到很多configure error，我们一一解决，基本都是相关软件开发包没有安装导致</str>

H. 阿里云上的centos 7.2怎么yum安装php 5.6

因之前通过网易的 centos 镜像，将阿里云的 centos 升级到最新版了，乘自己的项目尚未开始正式开发，遂将所有的相应环境都升级到最高。
查看 centos 版本：
[root@iZ23d ~]# cat /etc/centos-release
CentOS Linux release 7.2.1511 (Core)
1、删除之前的 php 版本：
[root@iZ23d ~]# yum remove php* php-common
Loaded plugins: langpacks
Repository base is listed more than once in the configuration
Repository updates is listed more than once in the configuration
Repository extras is listed more than once in the configuration
Repository centosplus is listed more than once in the configuration
No Match for argument: php-5.4.16
No Match for argument: php-5.4.16.tar.gz
No Match for argument: php-7.0.1RC1
No Match for argument: php-7.0.1RC1.tar.gz
No Match for argument: phpMyAdmin-4.4.0.tar.gz
No Match for argument: php-common
No Packages marked for removal
2、rpm 安装 Php7 相应的 yum源：
[root@iZ23d ~]# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
Retrieving https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

Preparing... ################################# [100%]
package webtatic-release-7-3.noarch is already installed
3、 直接yum安装php7：
[root@iZ23d ~]# yum install php70w
Loaded plugins: langpacks
Repository base is listed more than once in the configuration
Repository updates is listed more than once in the configuration
Repository extras is listed more than once in the configuration

[root@iZ23d2e6hoqZ ~]#
以上显示安装成功！
5、重启 Apache，查看 phpinfo :
[root@iZ23d ~]# systemctl restart httpd.service
检查phpinfo:

I. 请教centos php 多版本安装共存切换

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

J. 如何在Centos的linux操作系统安装php的memcache扩展

准备工作：
1、一台linux的服务器

2、下载相应版本的php源码，知道自己php的版本并且知道phpize的位置

3、懂基本的linux解压命令和编译
操作步骤：
1、通过ssh登陆到我们的服务器，找到我们的phpize位置，如果不知道下载跟目前使用版本相同的php源码重新编译一下
2、下载memcached的源码包，并解压安装

wgettar -zxvf memcache-3.0.8.tgz #解压cd memcache-3.0.8 #进入源码包/usr/local/php/bin/phpize #执行phpize./configure --with-php-config=/usr/local/php/php-config #准备编译make && make install #编译安装

3、配置php.ini文件在最后面添加扩展进去

vim /etc/php.iniextension=memcache.so

4、重启web服务器，我用的是apache

service httpd restart

5、编写一个phpinfo文件去查看有没有安装成功
