centos php 安装目录？php安装
很多朋友对于centos php 安装目录和php安装不太懂，今天就由小编来为大家分享，希望可以帮助到大家，下面一起来看看吧！
Centos7如何安装PHP7最新版
方法一、简单安装(通过yum)
1.安装epel-release
rpm-ivh
2.安装PHP7的rpm源
rpm-Uvh
3.安装PHP7
yum install php70w
方法二、编译安装
1.下载php7
wget-O php7.tar.gz
2.解压php7
tar-xvf php7.tar.gz
3.进入php目录
cd php-7.0.4
4.安装依赖包
#直接复制下面一行(不包括本行)
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-devel
5.编译配置(如果出现错误，基本都是上一步的依赖文件没有安装所致)
嫌麻烦的可以从这一步起参考PHP官方安装说明：
./configure\
--prefix=/usr/local/php\
--with-config-file-path=/etc\
--enable-fpm\
--with-fpm-user=nginx\
--with-fpm-group=nginx\
--enable-inline-optimization\
--disable-debug\
--disable-rpath\
--enable-shared\
--enable-soap\
--with-libxml-dir\
--with-xmlrpc\
--with-openssl\
--with-mcrypt\
--with-mhash\
--with-pcre-regex\
--with-sqlite3\
--with-zlib\
--enable-bcmath\
--with-iconv\
--with-bz2\
--enable-calendar\
--with-curl\
--with-cdb\
--enable-dom\
--enable-exif\
--enable-fileinfo\
--enable-filter\
--with-pcre-dir\
--enable-ftp\
--with-gd\
--with-openssl-dir\
--with-jpeg-dir\
--with-png-dir\
--with-zlib-dir\
--with-freetype-dir\
--enable-gd-native-ttf\
--enable-gd-jis-conv\
--with-gettext\
--with-gmp\
--with-mhash\
--enable-json\
--enable-mbstring\
--enable-mbregex\
--enable-mbregex-backtrack\
--with-libmbfl\
--with-onig\
--enable-pdo\
--with-mysqli=mysqlnd\
--with-pdo-mysql=mysqlnd\
--with-zlib-dir\
--with-pdo-sqlite\
--with-readline\
--enable-session\
--enable-shmop\
--enable-simplexml\
--enable-sockets\
--enable-sysvmsg\
--enable-sysvsem\
--enable-sysvshm\
--enable-wddx\
--with-libxml-dir\
--with-xsl\
--enable-zip\
--enable-mysqlnd-compression-support\
--with-pear\
--enable-opcache
6.正式安装
make make install
7.配置环境变量
vi/etc/profile
在末尾追加
PATH=$PATH:/usr/local/php/bin
export PATH
执行命令使得改动立即生效
source/etc/profile
8.配置php-fpm
cp php.ini-production/etc/php.ini
cp/usr/local/php/etc/php-fpm.conf.default/usr/local/php/etc/php-fpm.conf
cp/usr/local/php/etc/php-fpm.d/www.conf.default/usr/local/php/etc/php-fpm.d/www.conf
cp sapi/fpm/init.d.php-fpm/etc/init.d/php-fpm
chmod+x/etc/init.d/php-fpm
9.启动php-fpm
/etc/init.d/php-fpm start
如何在CentOS6下实现Apache+PHP+MySQL的快速安装
LAMP是一个免费、开源的解决方案，代表了Linux、Apache、MySQL、PHP，主要用作建立可行的通用的web服务器。那么如何在CentOS6下实现安装Apache+php+Mysql的快速安装？其具体安装配置步骤可以如下进行：
1.准备工作
使用yum进行安装，为了提高速度，最好先是修改为中国CentOS镜像服务器。目前国内有三个镜像可以选择，分别是：中国科学技术大学、163和Sohu的镜像，建议教育网用户选择中科大，电信用户选择163，他们的repo文件本博客作了备份如下：
下面命令是备份CentOS-Base.repo文件，并修改使用163镜像作为yum源：
mv/etc/yum.repos.d/CentOS-Base.repo/etc/yum.repos.d/CentOS-Base.repo.save
wget
mv CentOS6-Base-163.repo/etc/yum.repos.d/CentOS-Base.repo
2.更新系统内核
yum-y update
3.安装Apahce、Mysql、PHP
yum-y install httpd php mysql mysql-server
默认情况下，mysql数据目录位于/var/lib/mysql
4.安装相关组件:
yum install php-mysql php-gd php-imap php-ldap php-odbc
php-pear php-xml php-xmlrpc
5.安装MySQL管理工具phpMyAdmin
yum-y install phpMyAdmin
6.配置Apache随系统启动
chkconfig--levels 235 httpd on
/etc/init.d/httpd start
7.配置MySQL随系统启动
chkconfig--levels 235 mysqld on
/etc/init.d/mysqld start
8.设置数据库root密码
/usr/bin/mysqladmin-u root password'New+Password#www.yupengyan.com'
9.测试PHP是否安装成功
在 CentOS中 Apache的默认根目录是/var/www/html，配置文件/etc/httpd/conf/httpd.conf。其他配置存储在/etc/httpd/conf.d/目录。
CentOSyumphpmcrypt扩展安装方法
使用 yum install php-mcrypt安装mcrypt扩展时会提示没有安装包
Setting up Install Process
No package php-mcrypt available.
Error: Nothing to do
mcrypt是加密扩展库，加载了它可以用他里面自带的22种加密解密算法
CentOS6默认安装的是php5.3.2
默认的 redhat repos php中是没有 mcrypt扩展的
根据红帽的官方消息（）RHEL不打算添加PHP的mcrypt的支持

Thanks for the report.
We are not planning to ship mcrypt support for PHP.
解决方法：
从php官网下载新的php 5.3源码包后，解压到本地目录
进入解压目录下的 ext目录后会发现有 mcrypt，
进入 mcrypt目录
#cd/ext/mcrypt
#phpize
注意：如果报-bash:phpize not Found那么 yum install php-devel就可以使phpize进行动态编译安装扩展
#./configure-with-php-config=/usr/sbin/php/bin/php-config
#make&& make install
出现：
----------------------------------------------------------------------
Libraries have been installed in:
/var/php-5.3.10/ext/mcrypt/modules
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,-rpath-Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------
Build complete.
Don't forget to run'make test'.
Installing shared extensions:/usr/lib64/php/modules/
查看：
# php-m

已安装成功！
再次查看 phpinfo，可以看到mcrypt扩展详情。
