如何给Centos安装mcrypt库

Publish:

本文参照 具体步骤按照本人实际操作。

本文环境:

Centos 7 + php-fpm + nginx + mcrypt

首先确保Nginx和php-fpm已经安装并且配置好

Nginx配置如下

/etc/nginx/conf.d/default.conf

server {

# 监听端口,默认就是8000
listen 8000;

# 网站域名
server_name www.wecenter.com;

# 网站根目录(我是改成了/home/wwwroot)
    root /home/wwwroot;
    #root /usr/share/nginx/html;
    index index.php index.html index.htm;

    location / {
        try_files $uri $uri/ /index.php; #开启伪静态
    }

    # 错误页配置
    error_page 404 /404.html;
    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
        root /usr/share/nginx/html;
    }

    # php-fpm配置,即对于php后缀的,都是用php-fpm处理
    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
        #fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

PHP配置如下

/etc/php.ini
cgi.fix_pathinfo=0

php-fpm配置如下

/etc/php-fpm.d/www.conf

; The address on which to accept FastCGI requests.
; Valid syntaxes are:
;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific address on
;                            a specific port;
;   'port'                 - to listen on a TCP socket to all addresses on a
;                            specific port;
;   '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.
;listen = 127.0.0.1:9000
listen=/var/run/php-fpm/php-fpm.sock


; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
;       will be used.
; RPM: apache Choosed to be able to access some dir as httpd
;user = apache
user = nginx 
; RPM: Keep a group allowed to write in log dir.
;group = apache
group = nginx

新建测试文件info.php到目录/home/wwwroot

<?php phpinfo();?>

重启nginx和php-fpm

sudo systemctl restart php-fpm
sudo systemctl restart nginx.service
sudo systemctl reload nginx.service

打开浏览器测试

http://[Your_IP_Address]:8000/info.php

然后你就可以看到目前你的PHP相关的所有配置,如果页面没有出来,或者不成功,请对照以上步骤,仔细查阅,看看哪里写的不对。

安装mcrypt库

#确认系统是否已经安装了mcrypt
yum list installed|grep mcrypt

如果没有安装,请安装。

#安装命令
yum install libmcrypt libmcrypt-devel mcrypt mhash

安装php的mcrypt扩展(动态加载编译)

下载php下的mcrypt扩展或者直接下载php的完整安装包 http://cn.php.net/releases/ 网页下找到自己服务器的php版本,下载后tar解压(本人的是php5.4.16) 进入ext/mcrypt文件夹

tar -xzvf php-5.4.16.tar.gz
[wwwroot@localhost ~]# cd php-5.4.16/ext/mcrypt/

执行phpize命令(phpize是用来扩展php扩展模块的,通过phpize可以建立php的外挂模块,如果没有?yum install php53-devel里包含了,或者其他方法)

[wwwroot@localhost mcrypt]# whereis phpize    //为了确定phpize存在
phpize: /usr/bin/phpize /usr/share/man/man1/phpize.1.gz
[wwwroot@localhost mcrypt]# phpize
Configuring for:
PHP Api Version:         20090626
Zend Module Api No:      20090626
Zend Extension Api No:   220090626

执行完后,会发现当前目录下多了一些configure文件,最后执行php-config命令就基本完成了 执行以下命令,确保你的/usr/bin/php-config是存在的

[wwwroot@localhost mcrypt]# whereis php-config
php-config: /usr/bin/php-config /usr/share/man/man1/php-config.1.gz
[wwwroot@localhost mcrypt]# ./configure --with-php-config=/usr/bin/php-config

如果遇到以下错误(configure: error: no acceptable C compiler found in $PATH),请先安装gcc,

命令yum install gcc

直到不报错,出现:config.status: creating config.h,执行以下命令

[wwwroot@localhost mcrypt]# make && make install

最后的最后,会提示你如下,说明你大功告成了

Installing shared extensions:     /usr/lib64/php/modules/

顺便检查下/usr/lib64/php/modules/里的mrcypt.so扩展是否已经创建成功 然后的事就简单了,给你的php.ini添加一条extension=mcrypt.so

extension_dir=/usr/lib64/php/modules
extension=mcrypt.so

service php-fpm restart 重启php

[wwwroot@localhost mcrypt]# cd /etc/php.d
创建一个mrcypt.ini文件就行,里面写extension=mcrypt.so

[wwwroot@localhost php.d]# vim mcrypt.ini
;Enable mcrypt extension module
extension=mcrypt.so

检测Mcrypt是否安装成功

http://192.168.10.64:8000/info.php
页面上应该显示
mcrypt support:enabled
mcrypt_filter support:enabled
