安装nginx
yum install nginx
账号统一使用nginx
配置nginx
/etc/nginx/conf.d/ssl.afonddream.com.conf
/etc/nginx/cert #ssl 证书位置
user nginx;
http
#使用sock与php-fpm链接
# Upstream to abstract backend connection(s) for php
upstream php {
server unix:/dev/shm/php-cgi.sock;
# server 127.0.0.1:9000;
}
server {
listen 443;
server_name afonddream.com www.afonddream.com
##nginx日志不转化成ascii编码
log_escape_non_ascii off;
ssl on;
ssl_certificate cert/www.afonddream.com.pem;
ssl_certificate_key cert/www.afonddream.com.key;
ssl_session_timeout 5m;
ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_prefer_server_ciphers on;
root /www/wordpress-blog;
## This should be in your http block and if it is, it’s not needed here.
index index.php;
location = /favicon.ico {
log_not_found off;
access_log off;
}
location = /robots.txt {
allow all;
log_not_found off;
access_log off;
}
location / {
# This is cool because no php is touched for static content.
# include the “?$args” part so non-default permalinks doesn’t break when using query string
try_files $uri $uri/ /index.php?$args;
}
location ~ \.php$ {
#NOTE: You should have “cgi.fix_pathinfo = 0;” in php.ini
include fastcgi.conf;
fastcgi_intercept_errors on;
fastcgi_pass php;
}
location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
expires max;
log_not_found off;
}
}
配置php-fpm
/etc/php-fpm.d/www.conf
; RPM: apache Choosed to be able to access some dir as httpd
user = nginx
; RPM: Keep a group allowed to write in log dir.
group = nginx
;use socket instead of tcp
;listen = 127.0.0.1:9000
listen = /dev/shm/php-cgi.sock
listen.owner = nginx
listen.group = nginx
修改nginx 默认上传大小，默认是1M：
http{} 添加 client_max_body_size 20m 代表最大限制20M
修改php默认的文件上传大小，默认是是2M
; Maximum size of POST data that PHP will accept.
post_max_size = 20M
; Maximum allowed size for uploaded files.
; http://php.net/upload-max-filesize
upload_max_filesize = 20M
直接在服务器上修改wp-config.php ，填上你的数据库信息。确保防火墙和阿里云安全组已经开放相应的端口。http 80 https 443 .
然后浏览器访问：wp-admin/install.php 以便启动安装程序.
注意：
1使用相同的账号，避免权限问题,这里都是使用nginx
2低版本的php-pfm，可能不支持socket形式，与nginx连接
