centosyumphp53

① 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.a /usr/lib64/libmhash.a
ln -s /usr/local/lib/libmhash.la /usr/lib64/libmhash.la
ln -s /usr/local/lib/libmhash.so /usr/lib64/libmhash.so
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 \
--with-config-file-path=/usr/local/php/etc \

make ZEND_EXTRA_LIBS='-liconv'
make install

6.链接php可执行文件：
ln -s /usr/local/php/bin/php /usr/bin/php
ln -s /usr/local/php/bin/phpize /usr/bin/phpize
ln -s /usr/local/php/sbin/php-fpm /usr/bin/php-fpm

7.编辑php.ini配置文件：
cp /usr/src/php-5.5.25/php.ini-proction
/usr/local/php/etc/php.ini
ln -s /usr/local/php/etc/php.ini /etc/php.ini
vim /etc/php.ini

8.编辑php-fpm.conf配置文件：
cp /usr/local/php/etc/php-fpm.conf.default
/usr/local/php/etc/php-fpm.conf
vim /usr/local/php/etc/php-fpm.conf
[global]
pid = /home/php/pid/php-fpm.pid

pm.max_spare_servers = 6
request_terminate_timeout = 100

9.编写php-fpm启动脚本
vim /etc/init.d/php-fpm
#!/bin/sh
# chkconfig:
2345 90
10
#
Description:
Start and
Stop php-fpm
# Provides:

php-fpm
#
Default-Start:

#
Default-Stop:
0 1 6
prefix=/usr/local/php
exec_prefix=${prefix}
php_fpm_BIN=${prefix}/sbin/php-fpm
php_fpm_CONF=${prefix}/etc/php-fpm.conf
php_fpm_PID=/home/php/pid/php-fpm.pid
php_opts="--fpm-config $php_fpm_CONF --pid $php_fpm_PID"
wait_for_pid () {
try=0
while test $try -lt 35 ; do
case "$1" in
'created')
if [ -f "$2" ] ; then
try=''
break
fi
;;
'removed')
if [ ! -f "$2" ] ; then
try=''
break
fi
;;
esac
echo -n .
try=`expr $try + 1`
sleep 1
done
}
case "$1" in
start)
echo -n "Starting php-fpm..."
$php_fpm_BIN --daemonize $php_opts
if [ "$?" != 0 ] ; then
echo " failed"
exit 1
fi
wait_for_pid created $php_fpm_PID
if [ -n "$try" ] ; then
echo " failed"
exit 1
else
echo " done"
fi
;;
stop)
echo -n "Stoping php-fpm..."
if [ ! -r $php_fpm_PID ] ; then
echo "warning, no pid file found - php-fpm is not running ?"
exit 1
fi
kill -QUIT `cat $php_fpm_PID`
wait_for_pid removed $php_fpm_PID
if [ -n "$try" ] ; then
echo " failed. Use force-quit"
exit 1
else
echo " done"
fi
;;
force-quit)
echo -n "Terminating php-fpm "
if [ ! -r $php_fpm_PID ] ; then
echo "warning, no pid file found - php-fpm is not running ?"
exit 1
fi
kill -TERM `cat $php_fpm_PID`
wait_for_pid removed $php_fpm_PID
if [ -n "$try" ] ; then
echo " failed"
exit 1
else
echo " done"
fi
;;
restart)
$0 stop
$0 start
;;

kill -USR2 `cat $php_fpm_PID`
echo " done"
;;
*)
echo "Usage: $0 {start|stop|force-quit|restart|reload}"
exit 1
;;
esac

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

② 如何在CentOS 6上通过YUM安装Nginx和PHP

在CentOS 6上通过YUM安装Nginx和PHP-FPM：
第一步，在/etc/yum.repos.d/目录下创建一个源配置文件nginx.repo：
cd /etc/yum.repos.d/
vim nginx.repo

填写如下内容：
[nginx]
name=nginx repo
baseurl=nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=0
enabled=1
保存，则会产生一个/etc/yum.repos.d/nginx.repo文件。

下面直接执行如下指令即可自动安装好Nginx：
yum install nginx -y
安装完成，下面直接就可以启动Nginx了：
/etc/init.d/nginx start
现在Nginx已经启动了，直接访问服务器就能看到Nginx欢迎页面了的。

③ centos 下如何通过yum安装最新的php

remi源，这里的php版本较新，5.4，5.5，5.6都有，还有配套的各种扩展
rpms.famillecollet.com


Centos 6.默认下没有安装php组件，因此我们需要输入命令：yum -y install php 回车如下图。
不用管，程序会自动完成安装及配置。

Zend组件，Centos 6.3 里面是没有的，需要手动下载，及安装教程请点击下面链接：

到此前期的准备工作已完成，下面就要对Apache进行配置
输入命令 pd/conf/httpd.conf //打开Apache配置文件，
找到ServerTokens OS将“OS”改为“Prod “ 。//显示服务器运行错误信息。与下图一样，那么Apache你就配置成功了，如果不一样请仔细对比上面的教程是不是那个步骤少了#及字母拼写错了。
到此php运行环境便配置成功啦。

④ 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

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
Repository centosplus is listed more than once in the configuration

4、检查 php 版本：
[root@iZ23d ~]# php -v
PHP 7.0.0 (cli) (built: Dec 2 2015 20:42:32) ( NTS )
Copyright (c) 1997-2015 The PHP Group

[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:

⑥ 阿里云上的centos 7.2怎么yum安装php 5.6

阿里云Centos配置php环境 方法/步骤 打开putty工具，在主机名称中输入阿里云ecs的IP地址和端口。输入好后，点击“打开”进入。 进入putty界面后，输入系统账号和密码。提示一下密码是暗文的，输入密码时不会显示在屏幕上的。 进入系统后，输入命令进行安装。 安装apache: yum install httpd httpd-devel 启动apache: /etc/init.d/httpd start 此时输入服务器的IP地址，应该看到apache的服务页面，端口不用输，apache默认就是使用80端口 安装mysql: yum install mysql mysql-server 启动mysql: /etc/init.d/mysqld start 安装php yum install php php-devel 重启apache使php生效 /etc/init.d/httpd restart 安装php的扩展 yum install php-mysql php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc 安装完扩展之后需要再次重启apache /etc/init.d/httpd restart 最后在目录：/var/www/html/下建立一个PHP文件 代码内容如下： <?php phpinfo(); ?> 当你访问这个文件时，就能看到php版本以及所安装的插件信息了。 4 安装完所有的软件后，安装VPSMate面板。它提供界面化操作文件和控制软件。 本数据来源于网络地图，最终结果以网络地图最新数据为准。 我现在使用的是小鸟云。他们官网最近有活动蛮优惠，可以去看看！

⑦ CentOS6.5 用yum安装php报错

我之前安装也遇到过这个情况，建议用xampp这个软件集成包，把你的mysql和apacher卸载了，直接用这个就行，找个linux版本的。

⑧ centos6.6下怎么用yum安装php

是一个在Fedora和RedHat以及SUSE中的Shell前端软件包管理器。可以自动处理依赖性关系，并且一次安装所有依赖的软体包，无须繁琐地一次次下载、安装。使用yum安装PHP的前提准备：
1、yum update 检查一下系统更新 初次安装可能更新的时间会比较长，请耐心等待。
2、yum install gcc gcc-c++ ;安装gcc软件编译环境。

[root@lamp ~]# yum install php php-mysql php-common php-gd php-mbstring php-mcrypt php-devel php-xml
安装好php之后重启httpd ： /etc/init.d/httpd restart
设置成开机启动：
chkconfig httpd on
chkconfig mysqld on
整个过程我们不需要修改/etc/httpd/conf/httpd.conf 这就是版本高了的好处~
