一、Linux安装php7.3以及相关环境配置
安装相关环境
yum install -y gcc gcc-c++ make zlib zlib-devel pcre pcre-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers
php官网,找到https://www.php.net/downloads.php
下载地址,找到php-7.3.24.tar.gz
,右键复制地址,然后用wget下载(下载有点慢,可以用浏览器下载,然后再传到服务器上解压)。
wget https://www.php.net/distributions/php-7.3.24.tar.gz
解压:
tar -xzvf php-7.3.24.tar.gz
cd php-7.3.24
php参数配置:
./configure \
--prefix=/usr/local/php \
--exec-prefix=/usr/local/php \
--bindir=/usr/local/php/bin \
--sbindir=/usr/local/php/sbin \
--includedir=/usr/local/php/include \
--libdir=/usr/local/php/lib/php \
--mandir=/usr/local/php/php/man \
--with-config-file-path=/usr/local/php/etc \
--with-openssl \
--enable-mbstring \
--with-pdo-mysql \
--enable-fpm \
--with-curl
编译:
make && make install
在之前编译的源码包中,找到 php.ini-production,复制到/usr/local/php/etc下,并改名为php.ini:
cp php.ini-production /usr/local/php/etc/php.ini
将php源码编译目录下的 sapi/fpm/init.d.php-fpm 文件拷贝到系统配置 /etc/init.d 目录下并重命名为 php-fpm
[root@localhost php-7.3.24]# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
[root@localhost php-7.3.24]# chmod +x /etc/init.d/php-fpm
添加 php-fpm 配置文件
将php安装目录下的 /usr/local/php/etc/php-fpm.conf.default 文件拷贝同目录下并重命名为 php-fpm.conf
[root@localhost php-7.3.24]# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
添加 www.conf 配置文件
将php安装目录下的 /usr/local/php/etc/php-fpm.d/www.conf.default 文件拷贝同目录下并重命名为 www.conf
[root@localhost php-7.3.24]# cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf
添加php安装目录到系统环境变量
创建并打开文件php.sh
[root@localhost php-7.3.24]# vim /etc/profile.d/php.sh
添加:export PATH=$PATH:/usr/local/php/bin/:/usr/local/php/sbin/
使用source立即生效刚刚添加的php环境变量
[root@localhost php-7.3.24]# source /etc/profile.d/php.sh
启动php
[root@localhost php-7.3.24]# service php-fpm start
Starting php-fpm done
查看端口启动:php的fastcgi端口9000
[root@localhost php-7.3.24]# netstat -tnl
Active Internet connections (only servers)

设置php开机启动
修改系统配置目录下的 php-fpm 文件可执行权限
[root@localhost php-7.3.24]# chmod +x /etc/init.d/php-fpm
> 将系统配置目录下的 `php-fpm` 添加到 `系统服务`
[root@localhost php-7.3.24]# chkconfig --add php-fpm
> 设置 `php-fpm` `系统服务` 为开机启动
[root@localhost php-7.3.24]# chkconfig php-fpm on
重启电脑后:
[root@localhost ~]# netstat -tnl

二、公众号的配置以及引入文件
首先你必须有一个认证后的微信公众号
(或者点开发者工具-公众平台测试账号-扫码申请一个有分享接口权限的测试号
),然后把你的网站ip地址输入公众号ip白名单
。
步骤一:验证文件并且绑定域名
先登录微信公众平台进入“公众号设置”的“功能设置”里填写“JS接口安全域名”,并且把下载的xxxx.txt文件放至域名根目录下,下面说的jssdk.php我们也是放在域名根目录下
。
步骤二:引入JS文件
<script src="http://res.wx.qq.com/open/js/jweixin-1.2.0.js"></script>
<script>
window.onload = function (){
var url = (window.location.href).split('#')[0]
$.ajax({
type : "get",
//我这里是放在域名根目录下,如果在域名根目录下新建文件夹,则url:"http://自己的域名/文件夹名/jssdk.php?url="+url
url : "http://自己的域名/jssdk.php?url="+encodeURIComponent(url),
dataType : "jsonp",
jsonp: "callback",
jsonpCallback:"success_jsonpCallback",
success : function(data){
wx.config({
debug: false,
appId: data.appId,
timestamp: data.timestamp,
nonceStr: data.nonceStr,
signature: data.signature,
jsApiList: [
'onMenuShareTimeline',//
'onMenuShareAppMessage',
'onMenuShareQQ',
'onMenuShareWeibo',
'onMenuShareQZone'
]
});
},
error:function(data){
alert("连接失败!");
}
});
wx.ready(function () {
var shareData = {
title: '这是是分享标题',
desc: '这是是摘要',
link: url,
imgUrl: '域名根目录下的小图标文件的地址或者oss服务器下小图标文件的地址(能在浏览器上访问到图片就ok)'
};
wx.onMenuShareAppMessage(shareData);//分享给好友
wx.onMenuShareTimeline(shareData);//分享到朋友圈
wx.onMenuShareQQ(shareData);//分享给手机QQ
wx.onMenuShareWeibo(shareData);//分享腾讯微博
wx.onMenuShareQZone(shareData);//分享到QQ空间
});
wx.error(function (res) {
//alert(res.errMsg);//错误提示
});
}
</script>
url : "http://自己的域名/jssdk.php?url="+url,
这个域名不必须是目前的域名,如果你有多个域名,可以引用同一个jssdk.php文件。
步骤三:创建PHP文件 jssdk.php(对于jssdk.php文件我们可以直接放域名根目录,也可新建文件夹,用文件的话注意文件路径!)
<?php
$url = $_GET['url'];
class JSSDK {
private $appId;
private $appSecret;
private $url;
public function __construct($appId, $appSecret,$url) {
$this->appId = $appId;
$this->appSecret = $appSecret;
$this->url = $url;
}
public function getSignPackage() {
$jsapiTicket = $this->getJsApiTicket();
$protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://";
// $url = "$protocol$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
$url =$this->url;
$timestamp = time();
$nonceStr = $this->createNonceStr();
// 这里参数的顺序要按照 key 值 ASCII 码升序排序
$string = "jsapi_ticket=$jsapiTicket&noncestr=$nonceStr×tamp=$timestamp&url=$url";
$signature = sha1($string);
$signPackage = array(
"appId" => $this->appId,
"nonceStr" => $nonceStr,
"timestamp" => $timestamp,
"url" => $url,
"signature" => $signature,
"rawString" => $string
);
return $signPackage;
}
private function createNonceStr($length = 16) {
$chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
$str = "";
for ($i = 0; $i < $length; $i++) {
$str .= substr($chars, mt_rand(0, strlen($chars) - 1), 1);
}
return $str;
}
private function getJsApiTicket() {
// jsapi_ticket 应该全局存储与更新,以下代码以写入到文件中做示例
$data = json_decode(file_get_contents("jsapi_ticket.json"));
if ($data->expire_time < time()) {
$accessToken = $this->getAccessToken();
// 如果是企业号用以下 URL 获取 ticket
// $url = "https://qyapi.weixin.qq.com/cgi-bin/get_jsapi_ticket?access_token=$accessToken";
$url = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?type=jsapi&access_token=$accessToken";
$res = json_decode($this->httpGet($url));
$ticket = $res->ticket;
if ($ticket) {
$data->expire_time = time() + 7000;
$data->jsapi_ticket = $ticket;
$fp = fopen("jsapi_ticket.json", "w");
fwrite($fp, json_encode($data));
fclose($fp);
}
} else {
$ticket = $data->jsapi_ticket;
}
return $ticket;
}
private function getAccessToken() {
// access_token 应该全局存储与更新,以下代码以写入到文件中做示例
$data = json_decode(file_get_contents("access_token.json"));
if ($data->expire_time < time()) {
// 如果是企业号用以下URL获取access_token
// $url = "https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=$this->appId&corpsecret=$this->appSecret";
$url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$this->appId&secret=$this->appSecret";
$res = json_decode($this->httpGet($url));
$access_token = $res->access_token;
if ($access_token) {
$data->expire_time = time() + 7000;
$data->access_token = $access_token;
$fp = fopen("access_token.json", "w");
fwrite($fp, json_encode($data));
fclose($fp);
}
} else {
$access_token = $data->access_token;
}
return $access_token;
}
private function httpGet($url) {
$curl = curl_init();
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_TIMEOUT, 500);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, true);
curl_setopt($curl, CURLOPT_URL, $url);
$res = curl_exec($curl);
curl_close($curl);
return $res;
}
}
$jssdk = new JSSDK("wx********************a", "*************************",$url);
$signPackage = $jssdk->GetSignPackage();
$tmp=json_encode(array ('appId'=>$signPackage["appId"],'timestamp'=>$signPackage["timestamp"],'nonceStr'=>$signPackage["nonceStr"],'signature'=>$signPackage["signature"],'url'=>$signPackage["url"]));
$callback = $_GET['callback'];
echo $callback.'('.$tmp.')';
exit;
?>
只要改一下这一行为你自己的:
$jssdk = new JSSDK("wx********************", "*************************",$url);
最后,别忘了存放这个PHP的文件夹权限为可写(如果放在域名根目录则将access_token.json、jsapi_ticket.json、MP_verify_xxxxxxxx.txt权限为可写)。
这里我用的是
chmod -R 777 access_token.json
chmod -R 777 jsapi_ticket.json
chmod -R 777 MP_verify_xxxxxxxx.txt
(PS:微信对分享内容大小有限制,如果自定义图标文件过大,不然会导致描述不显示,图片最好控制在30Kb左右,图片比例5:4)
三、nginx配置-php文件的解析
server {
listen 80;
listen 443 ssl;
server_name xxxxx; #域名
ssl_certificate xxx/xxxxxxxxxx.pem;
ssl_certificate_key xxx/xxxxxxxxxx.key;
root /xxx/xxx;
location / {
index index.html index.htl index.php;
try_files $uri $uri/ /index.php?$args;
}
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /xxx/xxx$fastcgi_script_name;#这里的/xxx/xxx写root路径
include fastcgi_params;
}
location ^~ /assets/ {
gzip_static on;
expires max;
add_header Cache-Control public;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
四、遇到的问题
(1) 报500
php环境引起问题,没有在
php参数配置
的时候加配置--with-curl
(2)jssdk config:invalid url domain
切记一定要在自己申请的测试公众号添加安全域名
(3)调用ACCESS_TOKEN失败,直接在容器中CRUL这个接口会有41002的错误
curl 把url用双引号包住就可以了
(3)jssdk config:invalid signature
1.确认签名算法正确
微信 JS 接口签名校验工具
微信公众平台接口调试工具
与.php打印出来的日志相比较,确认signature是否一致,切记将下图中的url中的反斜杠给去掉,不然总会得出签名算法不正确,切记切记!!!
5.确保一定缓存access_token和jsapi_ticket
域名根目录下创建access_token.json、jsapi_ticket.json,并且设置权限:
chmod -R 777 access_token.json
chmod -R 777 jsapi_ticket.json
