Detailed description of httpd. conf files in apache

ServerRoot/Apache # The Path e: webapache # ServerRoot can be used to specify the httpd running Directory for the daemon process. after httpd is started, it will take the initiative to change the current directory in the process to this directory, therefore, if the specified file or directory is ServerRoot/Apache
# You can use the path e: webapache
# ServerRoot is used to specify the httpd running Directory for the daemon process. after httpd is started, it will automatically change 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 process is recorded in the file specified by PidFile. because httpd can actively copy itself, there are multiple httpd processes in the system, but only one process is the initial process, 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, a single connection can only be used to transmit an HTTP request once, while the KeepAlive parameter is used to support one connection in HTTP 1.1 and multiple transmission functions, in this way, multiple HTTP requests can be transmitted in one connection. Although only a newer browser can support this function, you can still open the application option.
MaxKeepAliveRequests 100
# MaxKeepAliveRequests is the maximum number of requests for an HTTP request that can be performed by a connection. Setting this value to 0 will support infinite transmission requests in one connection. In fact, no client program begged too many pages in a connection, and the connection is usually completed if the upper 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.
