Use in production for WordPress

[binaryfire]

Hi all

Has anyone been using Unit for production WordPress sites? I haven't been able to find any info on stability, conflicts, edge cases etc. I'm keen to migrate but I want to make sure it's as rock solid as FPM before I do.

Thanks!

@binaryfire yes it is stable and works good
but you need to plan good if you have multisite wp too

[johnnypea]

@yosefy any recommendations how to setup it with WP Multisite? Thank you.

@johnnypea in the end i use it only for single site and single site subdir
building conf json with templating. works great

[johnnypea]

@yosefy would you mind sharing example of a config for this case? Thanks.

if you interested i create template with cuelang
and run /usr/sbin/cue export /etc/unit/unit__conf1.cue
this way you only need to add new site line in #sites to create new application and route

import "strings"

#sites: [
  { host: "test1.com", php_ver: "7.4", sub_dir: ""},
  { host: "test2.com", php_ver: "8.3", sub_dir: "/ru"},
]



access_log: {
    path:   "/var/log/unit/access.log"
    format: "{\"source\":\"nginx\", \"host\":\"$host\", \"remote_addr\":\"$remote_addr\", \"time_local\":\"$time_local\", \"request\":\"$request_line\", \"status\":\"$status\", \"bytes_sent\":\"$body_bytes_sent\", \"referer\": \"$header_referer\", \"user_agent\": \"$header_user_agent\"}"
}

    http: {
        log_route: false
    }

    "*:80": {
        pass: "routes"

            recursive: true
            source: ["10.0.0.0/8","127.0.0.1"]
        }
    }
}
routes: [
for _, site in #sites {
    {
      match: {
        host: "\(site.host)"
        uri: [
          "\(site.sub_dir)/*.php",
          "\(site.sub_dir)/*.php/*",
          "\(site.sub_dir)/wp-admin/"
        ]
      }
      action: {
        rewrite: "`${ uri.replace('\(site.sub_dir)', '') }`"
        pass: "applications/\(site.host + strings.Replace(site.sub_dir, "/", "--", -1))/direct"
      }
    }
}
for _, site in #sites {
    {
      match: {
        host: "\(site.host)"
        uri: ["\(site.sub_dir)*"]
      }
      action: {
        share: "`/sites/\(site.host + strings.Replace(site.sub_dir, "/", "--", -1))${ uri.replace('\(site.sub_dir)', '') }`"

        }

    }
}

      stdout: "/var/log/unit/sites/\(site.host + strings.Replace(site.sub_dir, "/", "--", -1))_access.log"

@yosefy genius, thank you.

Hi, how do we handle permalinks to avoid the index.php in them?

i got this config:

{
  "listeners": {
    "*:8080": {
      "pass": "routes/wordpress"
    }
  },

      {

          "share": "/var/apphome$uri",
          "fallback": {
            "pass": "applications/wordpress/index"
          }

      }
    ]

}

Any ideas?
