Two MARIADB installation

The installation is basically consistent with the previous MySQL installation, just to differentiate the installed MYQSL we have redefined the configuration file/usr/local/mariadb/my.cnf/etc/my.cnf is the system default profile
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.gzmv mariadb-10.2.6-linux-glibc_214-x86_64 /usr/local/mariadbcd /usr/local/mariadb./scripts/mysql_install_db --user=mysql --basedir=/usr/local/mariadb/ --datadir=/data/mariadbcp support-files/my-small.cnf /usr/local/mariadb/my.cnfvi /usr/local/mariadb/my.cnf //定义basedir和datadir 可以省略cp support-files/mysql.server /etc/init.d/mariadbvim /etc/init.d/mariadb //定义basedir、datadir、conf以及启动XCV参数

There is a warning that you can follow the prompts to execute Systemctl daemon-reload

Three Apache Installation

httpd we use the source package installation, to pre-install two library files Apr and apr-util, these two files are also source package installation, are used trilogy installation method./configure make made Install
Apache is the name of a foundation, HTTPD is the package that we want to install, earlier its name is Apache
Apache official website www.apache.org
wget http://mirrors.cnnic.cn/apache/httpd/httpd-2.4.27.tar.gz
wget http://mirrors.hust.edu.cn/apache/apr/apr-1.5.2.tar.gz
wget http://mirrors.hust.edu.cn/apache/apr/apr-util-1.5.4.tar.gz
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 OS platform

tar zxvf httpd-2.4.27.tar.gztar zxvf apr-util-1.5.4.tar.gztar zxvf apr-1.5.2.tar.gzcd /usr/local/src/apr-1.5.2./configure --prefix=/usr/local/apr

Configure:error:no acceptable C compiler found in $PATH
Yum install-y gcc
/configure found at the end of the cannot remove Libtoot Note this no tube because we echo $? Prompt for no errors. Continue down to

 make && make install cd /usr/local/src/apr-util-1.5.4./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/aprmake && make install

Compile apr-util times wrong

The backslash here is the caret, plus it allows us to write a line of commands into multiple lines

yum provides pcre-configyum install -y pcre-develmake && make installls /usr/local/apache2.4/modules/usr/local/apache2.4/bin/httpd -M //查看加载的模块

/usr/local/apache2.4/bin/apachectl startps aux |grep httpd
