Configure Nginx under Mac

Nginx is a high-performance HTTP and reverse proxy server, but also a IMAP/POP3/SMTP server, let us understand the use of nginx.

Installing Nginx

Using Brew to install Nginx

install nginx

Wait for the installation of Nginx, we can do the Nginx configuration after installation.

Configure Nginx

The configuration files for Mac Nginx are:

/usr/local/etc/nginx/nginx.conf

Open the nginx.conf, you can do the relevant configuration.
Nginx Configuration Detailed:

#define Nginx running users and user groups to specify NGINX worker process running user and user group, by default run by nobody accountUser * * *;#the number of nginx processes, the recommended setting is equal to the total CPU core number. Worker_processes 4;#Global error log definition type, [Debug | info | notice | warn | error | crit], where the debug output log is most verbose and crit output log is minimalError_logLogs/error.Loginfo;#a process file that specifies the location of the storage file for the process IDPID Logs/nginx.pid;#a Nginx process opens the maximum number of file descriptors, the theoretical value should be the maximum number of open files (System value ulimit-n) and the number of nginx process, but the Nginx allocation request is not uniform, so we recommend that the value of ulimit-n consistent, you can use the command " Ulimit-n 65535 "to set other values. Worker_rlimit_nofile 4864;#Maximum number of operating modes and connectionsEvents {#Reference event model, use [kqueue | rtsig | epoll |/dev/poll | select | poll]; EPOLL model is a high-performance network I/O model in Linux version 2.6 and above, and if it runs on FreeBSD, it Use the Kqueue model.

The maximum number of client connections is determined by worker_processes and Worker_connections, which is max_clients=worker_processes*worker_connections, when acting as a reverse proxy, Max_ Clients changed to: max_clients = worker_processes * WORKER_CONNECTIONS/4. The maximum number of connections for a process is limited by the maximum number of open files for the Linux system process, and the worker_connections settings are not valid until the operating system command "Ulimit-n 65536" is executedWorker_connections 1024;}#setting up an HTTP serverhttp {#to use the MIME type of the set file, type the Mime.type file definition in the profile directory to tell Nginx to identify the file type.     includeMime.types; Default_type Application/octet-stream;#Default File Type    #charset utf-8; #默认编码    #used to set the format of the log, and what parameters to record, which is set to main, just for Access_log to record this type    #Log_format main ' $remote _addr-$remote _user [$time _local] "$request" '    #' $status $body _bytes_sent ' $http _referer '    #' "$http _user_agent" "$http _x_forwarded_for";Sendfile on;#Open the efficient file transfer mode, the sendfile instruction specifies whether Nginx calls the Sendfile function to output the file, for the normal application is set to ON, if used for downloading and other applications such as disk IO heavy load application, can be set to off to balance disk and network I/O processing speed, Reduce the load on the system.

Later, add nginx load balancer and reverse proxy.
