11.6 MARIADB Installation

• The MARIADB installation process is similar to MySQL, but the difference is that because we have both MARIADB and MySQL installed on the same machine, we need to tweak the configuration files and startup scripts to avoid conflicts.

Brief steps to install MARIADB:

• Cd/usr/local/src
• wget https://downloads.mariadb.com/MariaDB/mariadb-10.2.6/bintar-linux-glibc_214-x86_64/ Mariadb-10.2.6-linux-glibc_214-x86_64.tar.gz
• Tar zxvf mariadb-10.2.6-linux-glibc_214-x86_64.tar.gz
• MV Mariadb-10.2.6-linux-glibc_214-x86_64/usr/local/maridb
• Cd/usr/local/mariadb
• ./scripts/mysql_install_db--user=mysql--basedir=/usr/local/mariadb/--datadir=/data/mariadb/
• CP support-files/my-small.cnf/usr/local/mariadb/my.cnf #拷贝配置文件
• VI/USR/LOCAL/MARIADB/MY.CNF #定义basedir和datadir
  Basedir=/usr/local/mariadb
  Datadir=/data/mariadb
• CP support-files/mysql.server/etc/init.d/mariadb #拷贝启动脚本
• Vim/etc/init.d/mariadb #定义basedir, datadir,conf and startup parameters
  Basedir=/usr/local/mariadb
  Datadir=/data/mariadb
  conf= $basedir/my.cnf
  Then add the following statement to the START Command statement ()
  --defaults-file= "$conf"
  
• /ETC/INIT.D/MARIADB Start #启动mariadbl服务

11.7/8/9 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. Apache official website www.apache.org
• Apr and Apr-util are a common library of functions that allow httpd to be easily ported (from Linux to Windows) without caring for the underlying operating system platform, so installing HTTPD requires installing APR and Apr-util first.

Download httpd, Apr and Apr-util and unzip:
wget http://mirrors.cnnic.cn/apache/httpd/httpd-2.4.29.tar.gz
wget http://mirrors.hust.edu.cn/apache/apr/apr-1.6.3.tar.gz
wget http://archive.apache.org/dist/apr/apr-util-1.5.4.tar.gz
Tar zxvf httpd-2.4.29.tar.gz
Tar zxvf apr-1.6.3.tar.gz
Tar zxvf apr-util-1.5.4.tar.gz

Install apr-1.6.3:

cd/usr/local/src/apr-1.6.3
./configure--PREFIX=/USR/LOCAL/APR
Make && make install

Install apr-util-1.5.4:

cd/usr/local/src/apr-util-1.5.4
./configure--prefix=/usr/local/apr-util--WITH-APR=/USR/LOCAL/APR
Make && make install

Install httpd-2.4.29:
cd/usr/local/src/httpd-2.4.29
./configure \//The backslash here is a caret, plus it allows us to write a line of commands into multiple lines
--prefix=/usr/local/apache2.4\
--with-apr=/usr/local/apr\
--with-apr-util=/usr/local/apr-util\
--enable-so\//indicates support for dynamic expansion modules
--enable-mods-shared=most
Make & make Install

• Ls/usr/local/apache2.4/modules #查看可用的扩展模块
  
• /usr/local/apache2.4/bin/httpd-m #查看加载的模块
  
• /usr/local/apache2.4/bin/apachectl Start #启动httpd服务
• PS Aux|grep httpd #查看httpd进程
• NETSTAT-LNTP #查看httpd监听的端口
  

Problems encountered during installation:

• Question 1:
  Issues encountered installing apr-util-1.6.1:
• Workaround: Missing Expat-devel Package
  Yum Install Expat-devel
  
• Question 2:
  Issues encountered installing HTTPD:
• Workaround: The problem is found online because Apr-util with the latest version 1.6, changed back to 1.5.4 version, problem solved.
