MARIADB and Apache Installation

11.6 MARIADB Installation

Preparatory work

Because the MARIADB binary package image source is in a foreign address, the package is pre-downloaded to the local physical machine, and the package is uploaded to the virtual machine/USR/LOCAL/SRC directory for installation using the Lrzsz tool.

Install the Lrzsz tool First:
[email protected] src]# Yum install-y lrzsz

To upload a local package to a virtual terminal:
[Email protected] ~]# CD/USR/LOCAL/SRC
[[email protected] src]# ls
Mysql-5.6.35-linux-glibc2.5-x86_64.tar.gz
[Email protected] src]# RZ

[[email protected] src]# ls
Mariadb-10.2.6-linux-glibc_214-x86_64.tar.gz mysql-5.6.35-linux-glibc2.5-x86_64.tar.gz
Installing MARIADB

Initialization

Unpack the package:
[Email protected] mariadb]# tar zxvf mariadb-10.2.6-linux-glibc_214-x86_64.tar.gz

[Email protected] src]# MV MARIADB-10.2.6-LINUX-GLIBC_214-X86_64/USR/LOCAL/MARIADB
[Email protected] src]# cd/usr/local/mariadb

Initialization
[Email protected] mariadb]#/scripts/mysql_install_db--user=mysql--datadir=/data/mariadb
Configure MARIADB

[email protected] mariadb]# CP support-files/my-small.cnf/usr/local/mariadb/my.cnf

[email protected] mariadb]# CP support-files/mysql.server/etc/init.d/mariadb
To configure the startup script:

[Email protected] mariadb]# vim/etc/init.d/mariadb
Basedir=/usr/local/mariadb
Datadir=/data/mariadb
conf= $basedir/my.cnf
Mark

Start the MARIADB service

To detect if the MySQL service is running:
[[Email protected] mariadb]# PS aux |grep mysql
Root 1326 0.0 0.0 115376 612? S 16:42 0:00/bin/sh/usr/local/mysql/b
MySQL 1848 0.1 44.9 981244 453044? Sl 16:42 0:19/usr/local/mysql/bin/mysqlysql--log-error=/data/mysql/centos-01.err--pid-file=/data/mysql/ Centos-01.pid--socket=/t
Root 2780 0.0 0.0 112664 972 pts/1 r+ 21:48 0:00 grep--color=auto MySQL

Because MySQL and mariadb listen to the same port, in order to avoid conflict, it is necessary to close the MySQL service first:
[[email protected] mariadb]# systemctl stop MySQL

To start the MARIADB service:
[[email protected] mariadb]#/etc/init.d/mariadb start
Reloading systemd: [OK]
Starting mariadb (via Systemctl): [OK]
Note: If only one of the services in MySQL and mariadb is installed on the system, you can put the startup script directly in the/etc/file to set the boot up.

11.7-11.9 Apache Installation

Apache is the name of a foundation, HTTPD is the package we want to install, the early name of it is called Apache. HTTPD uses a common function library Apr and Apr-util, which allows httpd to be easily ported (from Linux to Windows) without caring for the underlying operating system platform.
Apache official website www.apache.org.

The APR libraries used by httpd2.2 and httpd2.4 are different, and the APR that comes with the CENTOS7 system does not match, so you need to install the APR library file using Yum.

Preparatory work

Download the required Packages

Apache Pack:
[Email protected] src]# wget http://mirrors.cnnic.cn/apache/httpd/httpd-2.4.27.tar.gz

Apr Pack:
[Email protected] src]# wget http://mirrors.hust.edu.cn/apache/apr/apr-1.5.2.tar.gz

Apr-util Package:
[Email protected] src]# wget http://mirrors.hust.edu.cn/apache/apr/apr-util-1.5.4.tar.gz
Unpack the Package

[Email protected] src]# tar zxvf httpd-2.4.27.tar.gz

[Email protected] src]# tar zxvf apr-1.5.2.tar.gz

[Email protected] src]# tar zxvf apr-util-1.5.4.tar.gz
Install Apr Package

[Email protected] src]# CD apr-1.5.2
Configuration:
[Email protected] apr-1.5.2]#/configure--PREFIX=/USR/LOCAL/APR

Error:
Configure:error:in /usr/local/src/apr-1.5.2‘:<br/>configure: error: no acceptable C compiler found in $PATH<br/>See config.log ' for more details
Description: A C language-related compiler was missing.

Workaround:
[email protected] apr-1.5.2]# Yum install-y gcc*
Install the GCC compiler.

[Email protected] apr-1.5.2]#/configure--PREFIX=/USR/LOCAL/APR

Configuration is successful!

Compile and install:
[[email protected] apr-1.5.2]# make

Note: APR 1.6.2 has been changed, the encryption settings are made, and the following commands are required for compiling (otherwise, the library file cannot be called when Apache is installed):

[Email protected] httpd-2.4.27]# cc= "gcc-m64"./configure--prefix=/usr/local/apr
