Detailed description of httpd. conf files in Apache

# You can use the absolute path e: webapache
# Serverroot is used to specify the httpd running Directory of the Daemon. After httpd is started, it automatically changes the current directory of the process to this directory, therefore, if the specified file or directory is a relative path, the actual path is located under the path defined by serverroot.
Pidfile logs/httpd. pid
# The Process Number of the httpd daemon is recorded in the file specified by pidfile. Because httpd can automatically copy itself, there are multiple httpd processes in the system, but only one process is the process initially started, it is the parent process of other processes. Sending signals to this process affects all httpd processes. The process number of the httpd parent process is recorded in the file defined by pidfile.
Timeout 300
# Timeout defines the timeout interval between the client program and the server. After the timeout interval (in seconds) is exceeded, the server will be disconnected from the client.
Keepalive on
# In http 1.0, only one http request can be transmitted over one connection, while the keepalive parameter is used to support one connection and multiple transmission functions in http 1.1, in this way, multiple http requests can be transmitted in a connection. Although this function is only supported by newer browsers, this option is still enabled.
Maxkeepaliverequests 100
# Maxkeepaliverequests is the maximum number of http requests that a connection can perform. Setting this value to 0 will allow unlimited transmission requests in one connection. In fact, no client program requests too many pages in a single connection. Generally, the connection is completed if this limit is not reached.
Keepalivetimeout 15
# Keepalivetimeout: Test the time between multiple requests in a connection. If the server has completed a request but has never received the next request from the client program, after the interval exceeds the value set by this parameter, the server will be disconnected.
