Redmine

Good evening
Help please configure redmine + ngnix + thin.
What I did:
1. Install and configure redmine in conjunction with apache + passenger. This to work, but I do not like speed. Solved all set to ng nix + Thein.
2. Install nginx, set it up and test it by running phpmyadmin. Everything works.
3. Run gem install thin. Received an answer something like:

Successfully
unable to convert "\ xC3" to UTF-8 in conversion from ASCII-8BIT to UTF-8 to US-A
SCII for CHANGELOG, skipping
1 gem installed

4. Add a line to ngnix.conf, this content:

upstream thin_cluster {
server unix:/tmp/thin.0.sock;
}
server {
listen 80;
server_name mysite.ru;
access_log /var/log/nginx/redmine-proxy-access;
error_log /var/log/nginx/redmine-proxy-error;

charset utf-8;
root /disk2/www/redmine/public;
proxy_redirect off;
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;

client_max_body_size 50m;
client_body_buffer_size 10m;

proxy_connect_timeout 90;
proxy_send_timeout 90;
proxy_read_timeout 90;

proxy_buffer_size 4k;
proxy_buffers 4 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;

location / {
try_files $uri/index.html $uri.html $uri @cluster;
}
location @cluster {
proxy_pass http://thin_cluster;
}
}

5. Create a directory and file /etc/thin/redmine.yml with the contents:
pid: tmp/pids/thin.pid
group: redmine
wait: 30
timeout: 30
log: log/thin.log
max_conns: 1024
require: []
environment: production
max_persistent_conns: 512
servers: 1
daemonize: true
user: redmine
socket: /tmp/thin.sock
chdir: /disk2/www/redmine
6. What to do next, I Do not Know. Tried to start to go at your own site, but nothing works. Tell me what I did or what I'm doing wrong.
