Nextcloud update index, pseudo-static, performance optimization

1. After directly uploading or synchronizing files to the server, update the file index

#Scan all files for all users and update the index.

sudo -u www php occ files:scan --all

Pay attention to the PHP and OCC file paths, you can also write the absolute path directly:

sudo -u www /usr/local/php8.0/bin/php /home/wwwroot/www.example.com/occ files:scan --all

#Only scan the specified user or specified folder and update the index.

List all users:

sudo -u www php occ user:list

Only scan files of test user:

sudo -u www php occ files:scan test

Scan the user's specified directory:

sudo -u www php occ files:scan --path="/test/files/download"

2. Nextcloud pseudo-static rules

Three: Solving 423 locked

#Temporary solution

Enter maintenance mode:

sudo -u www php occ maintenance:mode --on

Clear the oc_file_locks table:

delete * from oc_file_locks; or truncate table oc_file_locks;

Exit maintenance mode:

sudo -u www php occ maintenance:mode --off

#Complete solution

Refer to the official website: https ://docs.nextcloud.com/server/latest/admin_manual/configuration_server/caching_configuration.html?highlight=cache

Configure Redis cache for Nextcloud, add the following configuration in the config/config.php file:

'memcache.locking' => '\OC\Memcache\Redis', 'redis' => [ 'host' => '127.0.0.1', 'port' => 6379, 'user' => 'Redis username', 'password' => 'Redis password', 'dbindex' => 0, 'timeout' => 1.5, 'read_timeout' => 1.5, ]

Four: Performance Optimization

#Memory cache optimization

APCu (official recommendation):

Install the APCu extension for PHP and add the following configuration in the config/config.php file:

'memcache.local' => '\OC\Memcache\APCu',

Redis (officially said that multiple servers may cause problems, and the single-machine speed is not as good as APCu):

'memcache.local' => '\OC\Memcache\Redis', 'memcache.distributed' => '\OC\Memcache\Redis', 'memcache.locking' => '\OC\Memcache\Redis', 'redis' => [ 'host' => '127.0.0.1', 'port' => 6379, 'user' => 'Redis username', 'password' => 'Redis password', 'dbindex' => 0, 'timeout' => 1.5, 'read_timeout' => 1.5, ]

#PHP optimization

upload_max_filesize 5G post_max_size 5G max_input_time 3600 max_execution_time 3600 memory_limit = 512M output_buffering = 0 upload_tmp_dir = /dev/shm/client_body_temp

#NGINXOptimization

client_max_body_size 5G fastcgi_read_timeout 3600 client_body_temp_path /dev/shm/client_body_temp

When the temporary file directory is set to memory, a large memory server is recommended and SWAP must be configured.

#If Nextcloud is behind a CDN or load balancing

With front-end permissions: It is recommended to turn off proxy_buffering or increase the value of proxy_max_temp_file_size.

No front-end permission: add_header X-Accel-Buffering no;

#Improve upload performance in high upload bandwidth environment, adjust the block size on Nextcloud side (default is 10M)

sudo -u www php occ config:app:set files max_chunk_size --value 20971520
