Linux3 Source Code Installation

Source Code Installation: There is no dependency through Yum (installing MySQL is installing MySQLServer). RPM Update, if you do not install the software to go back to the installation. Application and system commands are placed in different directories (bin,sbin,usr/bin,usr/sbin), and if Yum cannot be found and there is no RPM package, it will need to be installed after compiling itself. Condition:1-qa | grep gcc: If you find LIBGCC, this is not a compilation environment, just a library. [Email protected]:/# apt-get install gcc2. Application source code. Open the browser to download Nginx source code (development development version is relatively new but unstable, stable is stable version, beta test version)

Pre-compilation configuration work (check work) (which directory to install, whether dependent programs are required, etc.).

After entering the nginx-1.13. 8 root directory There will be a config file, or script, the program is compiled based on config, so config is used to complete the pre-compilation configuration work.

management of users and groups:

Linux accounts are divided into 2 types of user accounts and group accounts. User account: Divided into ordinary users and super users, ordinary users can only operate in a specific folder, the Superuser can operate on all folders and control of ordinary users. Group accounts: Groups are collections of users, components are private groups and public groups, and it is recommended that a user who does not specify a group creates a private group with the same name as the user (private groups and user names with the same name and only a user), and the standard group can accommodate multiple users. [Email protected]:/etc# vim passwd: Stores the user information created by the system each row of columns (user name, login name: password, x is ciphertext: ID Number: Group identification number: Description: Log in after the directory: command interpreter, the root user login in the default to use the Bash interpreter ,/usr/sbin/Nologin is a system built-in account, some features, is not able to log on the system root:x:0:0:root:/root:/bin/bashdaemon:x:1:1:daemon:/usr/sbin:/usr/sbin/nologinbin:x:2:2:bin:/bin:/usr/sbin/nologinsys:x:3:3:sys:/dev:/usr/sbin/nologinsync:x:4:65534:sync:/bin:/bin/syncsystemd-timesync:x:100:102:systemd time synchronization,,,:/run/systemd:/bin/falsesystemd-NETWORK:X:101:103:SYSTEMD Network Management,,,:/run/systemd/netif:/bin/falsesystemd-resolve:x:102:104:systemd Resolver,,,:/run/systemd/resolve:/bin/falsesystemd-BUS-PROXY:X:103:105:SYSTEMD Bus proxy,,,:/run/systemd:/bin/falsesyslog:x:104:108::/home/syslog:/bin/false_apt:x:105:65534::/nonexistent:/bin/falsemessagebus:x:106:110::/var/run/dbus:/bin/falseuuidd:x:107:111::/run/uuidd:/bin/false
