linux 安装解压phpmyadmin 后，出现502错误

今天在linux安装解压phpmyadmin后,用IP访问出现502错误，查看了报错日志，显示如下：

2017/05/07 15:14:10 [crit] 29327#29327: *16 connect() to unix:/var/run/php5-fpm.sock failed (2: No such file or directory) while connecting to upstream, client: 183.7.254.***, server: 115.159.204.***, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "115.159.204.***:8080"

最后发现，是nginx的配置错误。 原来代码如下：

server {
    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;

    root /var/www/laravel/public;
    index index.php index.html index.htm;

    server_name server_domain_or_IP;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ \.php$ {
        try_files $uri /index.php =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

修改后：

server {
    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;

    root /var/www/laravel/public;
    index index.php index.html index.htm;

    server_name server_domain_or_IP;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ \.php$ {
                try_files $uri /index.php =404;
                fastcgi_split_path_info ^(.+\.php)(/.+)$;
                fastcgi_pass unix:/var/run/php7.1-fpm.sock;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                include fastcgi_params;
        }
}

原因： 我没有php5-fpm，我用的是php7.1-fpm
