FastCGIcache

WordpressでNginx(FastCGIcache)の設定

worker_rlimit_nofile

$ cat /proc/sys/fs/file-max
# 379002
# 10%前後
# 40000 etc..

worker_connections

# worker_rlimit_nofile / 4 くらい
# 2048 or 4096 etc..

$ chown -R nginx:nginx /var/lib/php/session
$ chown -R nginx:nginx /var/www/html

$ service nginx start
# Redirecting to /bin/systemctl start nginx.service

$ service php-fpm start
# Redirecting to /bin/systemctl start php-fpm.service

$ chkconfig nginx on
# systemctl enable nginx.service
$ chkconfig php-fpm on
# systemctl enable php-fpm.service

###PHP動作確認

/usr/share/nginx/html/phpinfo.php
<?php 
//ドキュメントルート適宜変更
phpinfo();

BASIC認証

$ yum install -y httpd-tools
$ cd /etc/nginx
$ htpasswd -c .htpasswd ユーザー名
/etc/nginx/nginx.conf
server {
    location / {
        auth_basic "Restricted";
        auth_basic_user_file /etc/nginx/.htpasswd;
    }
