MariaDB安装(相似于mysql安装)

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.gzphp

  1. 解压二进制已编译包
[root@localhost src]# tar zxf mariadb-10.2.6-linux-glibc_214-x86_64.tar.gz
  1. 移动至/usr/local/下
[root@localhost src]# mv mariadb-10.2.6-linux-glibc_214-x86_64 /usr/local/mariadb
[root@localhost local]# cd mariadb/
  1. 初始化脚本，指定basedir和datadir
# 这里跟mysql安装不一样的地方是须要额外指定basedir

[root@localhost mariadb]# ./scripts/mysql_install_db --user=mysql --basedir=/usr/local/mariadb/ --datadir=/data/mariadb
Installing MariaDB/MySQL system tables in '/data/mariadb' ...
OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !
To do so, start the server, then issue the following commands:

'/usr/local/mariadb//bin/mysqladmin' -u root password 'new-password'
'/usr/local/mariadb//bin/mysqladmin' -u root -h localhost.localdomain password 'new-password'

Alternatively you can run:
'/usr/local/mariadb//bin/mysql_secure_installation'

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the MariaDB Knowledgebase at http://mariadb.com/kb or the
MySQL manual for more instructions.

You can start the MariaDB daemon with:
cd '/usr/local/mariadb/' ; /usr/local/mariadb//bin/mysqld_safe --datadir='/data/mariadb'

You can test the MariaDB daemon with mysql-test-run.pl
cd '/usr/local/mariadb//mysql-test' ; perl mysql-test-run.pl

Please report any problems at http://mariadb.org/jira

  1. 拷贝配置文件（按服务器内存选择，这里测试选择my-small.cnf
# 这里是实现mysql和mariadb同存于一个机器中的作法
# 若是你的主机内只有mariadb，那么直接复制到/etc命令下，命名为my.cnf也行；对于的basedir也一样修改便可
[root@localhost mariadb]# cp support-files/my-small.cnf /usr/local/mariadb/my.cnf
[root@localhost mariadb]# vi /usr/local/mariadb/my.cnf 
在[mysqld]下插入下面的内容
basedir=/usr/local/mariadb
datadir=/data/mariadb
  1. 拷贝启动脚本至/etc/init.d/目录下，并修改内容
[root@localhost mariadb]# cp support-files/mysql.server /etc/init.d/mariadb
[root@localhost mariadb]# vi /etc/init.d/mariadb 
修改内容
basedir=/usr/local/mariadb
datadir=/data/mariadb
confdir=$basedir/my.cnf    #新增

并在下面启动项内添加--defaults-file选项加载指定的配置文件
$bindir/mysqld_safe --defaults-file="$confdir" --datadir="$datadir" --pid-file="$mysqld_pid_file_path" "$@" &
  1. 启动脚本并验证是否成功
[root@localhost mariadb]# /etc/init.d/mariadb start
Reloading systemd:                                         [  肯定  ]
Starting mariadb (via systemctl):                          [  肯定  ]

[root@localhost mariadb]# ps aux | grep mysql
root       3466  0.5  0.1 115392  1736 ?        S    13:04   0:00 /bin/sh /usr/local/mariadb//bin/mysqld_safe --defaults-file=/usr/local/mariadb/my.cnf --datadir=/data/mariadb --pid-file=/data/mariadb/localhost.localdomain.pid
mysql      3588 12.7  5.7 1125028 57864 ?       Sl   13:04   0:00 /usr/local/mariadb/bin/mysqld --defaults-file=/usr/local/mariadb/my.cnf --basedir=/usr/local/mariadb/ --datadir=/data/mariadb/ --plugin-dir=/usr/local/mariadb/lib/plugin --user=mysql --log-error=/data/mariadb/localhost.localdomain.err --pid-file=/data/mariadb//localhost.localdomain.pid --socket=/tmp/mysql.sock --port=3306
root       3624  0.0  0.0 112676   972 pts/0    S+   13:04   0:00 grep --color=auto mysql

注意第4步中拷贝、重命名配置文件的过程你能够任意存储，只要在启动脚本内指定好配置文件的路径，就能够安装启动成功。html

安装apache

apache是一个基金会的名字，httpd才是要安装的软件包，其早期名字为apache。mysql

Apache官网 www.apache.orglinux

软件包下载地址

因为软件更新，下面的地址连接截止为...
到http://mirrors.cnnic.cn/apache/查看当前版本号

httpd:      http://mirrors.cnnic.cn/apache/httpd/httpd-2.4.28.tar.gz 
apr：       http://mirrors.cnnic.cn/apache/apr/apr-1.6.3.tar.gz
apr-util:   http://mirrors.cnnic.cn/apache/apr/apr-util-1.6.1.tar.gz

软件安装

apr和apr-utilc++

  1. 先安装apr
[root@localhost src]# tar -zxvf apr-1.6.3.tar.gz
[root@localhost src]# cd apr-1.6.3/
[root@localhost apr-1.6.3]# ./configure --prefix=/usr/local/apr

# 判断是否编译成功
[root@localhost src]# echo $?
0
[root@localhost src]# make && make install
  1. 安装apr-util
[root@localhost src]# tar -zxvf apr-util-1.6.1.tar.gz 
[root@localhost src]# cd apr-util-1.6.1
[root@localhost apr-util-1.6.1]# ./configure --prefix=/usr/loca/apr-util --with-apr=/usr/local/apr
[root@localhost apr-util-1.6.1]# echo $?
0
[root@localhost src]# make && make install
  1. 安装apache2.4
[root@localhost src]# tar -zxvf httpd-2.4.28.tar.gz
[root@localhost src]# cd httpd-2.4.28
[root@localhost httpd-2.4.28]# ./configure --prefix=/usr/local/apache2.4  --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --enable-so --enable-mods-shared=most
[root@localhost httpd-2.4.28]# echo $?
0
[root@localhost httpd-2.4.28]# make && make install

编译参数说明：sql

--enable-so 支持动态扩展模块
如php模块，其实质为一个.so文件，经过apache的配置文件制定php模块位置，来加载php，在apache须要php解析时才调用。
--enable-mods-shared=most 容许大多数的模块扩展到apache主进程

查看编译时的参数apache

[root@localhost ~]# cat /usr/local/apache/build/config.nice 
#! /bin/sh
#
# Created by configure

"./configure" \
"--prefix=/usr/local/apache" \
"--with-apr=/usr/local/apr" \
"--with-apr-util=/usr/local/apr-util/" \
"--enable-so" \
"--enable-mods-shared=most" \
"$@"

软件安装时可能会遇到的问题

  1. ./configure编译apr时提示（不是错误）：
[root@localhost apr-1.6.3]# ./configure --prefix=/usr/local/apr
rm: cannot remove 'libtoolT': No such file or directory
config.status: executing default commands

[root@localhost apr-1.6.3]# echo $?
0
  1. make安装apr-util时报错：
xml/apr_xml.c:35:19: 致命错误：expat.h：没有那个文件或目录
 #include <expat.h>
                   ^
编译中断。

解决：缺乏expat-devel包网络

yum install -y expat-devel
  1. ./configure httpd时报错：
configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/

解决：缺乏prce库（正则相关的库）dom

yum install -y pcre-devel
  1. make http时报错：
...
/usr/local/apr-util/lib/libaprutil-1.so: undefined reference to `XML_StopParser'
/usr/local/apr-util/lib/libaprutil-1.so: undefined reference to `XML_Parse'

make[1]: *** [all-recursive] 错误 1
make[1]: 离开目录“/usr/local/src/httpd-2.4.28/support”
make: *** [all-recursive] 错误 1

解决：安装libxml2-devel包

详细步骤参见：https://my.oschina.net/LuCastiel/blog/1590706

可能缺乏的软件包

编译安装前提

yum install -y gcc gcc-c++

安装apr/apr-util/httpd

yum install -y expat-devel pcre-devel
