安装mariadb（二进制免编译包）

• 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/mariadb
• 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
• vi /usr/local/mariadb/my.cnf //定义basedir和datadir,如果这里不定义的话，由于以前安装过mysql，mysql服务启动就会调用/etc/my.cnf里的datadir，下面的服务数据库就会出错

  vi /usr/local/mariadb/my.cnf# The MySQL server[mysqld]basedir = /usr/local/mariadbdatadir = /data/mariadbport = 3306

  [root@akuilinux01 mariadb]# ps aux |grep mysqlroot 1838 0.2 0.0 115388 1748 ?

• cp support-files/mysql.server /etc/init.d/mariadb

• vim /etc/init.d/mariadb //定义basedir、datadir、conf以及启动参数
  如果不是同时安装mysql和mariadb，就不用定义conf

  basedir=/usr/local/mariadbdatadir=/data/mariadbconf=$basedir/my.cnf# may be overwritten at next upgrade. $bindir/mysqld_safe --defaults-file="$conf" --datadir="$datadir" --pid-file="$mysqld_pid_file_path" "$@" &

• /etc/init.d/mariadb start

安装Apache

• Apache是一个基金会的名字，httpd才是我们要安装的软件包，早期它的名字就叫apache
• Apache官网www.apache.org
• wget http://mirrors.cnnic.cn/apache/httpd/httpd-2.4.33 .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和apr-util是一个通用的函数库，它让httpd可以不关心底层的操作系统平台，可以很方便地移植（从linux移植到windows）
• tar zxvf httpd-2.4.26.tar.gz
• tar zxvf apr-util-1.5.4.tar.gz
• tar zxvf apr-1.5.2.tar.gz
• cd /usr/local/src/apr-1.5.2
• ./configure --prefix=/usr/local/apr
• make && make install
• cd /usr/local/src/apr-util-1.5.4
• ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
• make && make install
• cd /usr/local/src/httpd-2.4.27

• //enable-so支持动态扩展模块，最后一个是支持大多数动态模块 这里的反斜杠是脱义字符，加上它我们可以把一行命令写成多行

  ./configure \--prefix=/usr/local/apache2.4 \--with-apr=/usr/local/apr \--with-apr-util=/usr/local/apr-util \--enable-so \--enable-mods-shared=most\\ 指定支持大多数模块

  configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/[root@aminglinux-01 httpd-2.4.27]# yum install -y pcre-devel

• make && make install
• ls /usr/local/apache2.4/modules //动态模块目录
• /usr/local/apache2.4/bin/httpd -M //查看加载的模块 或者/usr/local/apache2.4/bin/apachectl -M
• /usr/local/apache2.4/bin/apachectl start //启动命令
• 启动错误
