本文详细介绍了LAMP（Linux, Apache, MySQL, PHP）环境的安装过程，包括MySQL的安装、Apache的编译与安装以及PHP的配置。在MySQL安装中，涉及了数据目录的设置和权限配置；在Apache部分，提到了编译安装过程中可能遇到的问题及解决办法；在PHP配置中，重点讲解了如何使Apache支持PHP并验证安装是否成功。" 119518282,10638140,力扣链表专题 - 设计链表解析与实现,"['链表', '数据结构', '算法', 'Java', 'JavaScript']

MYSQl安装

为了方便管理把软件包放到此目录下

[root@jing ~]# cd /usr/local/src
[root@jing src]# ls
apr-1.6.5.tar.gz       httpd-2.4.46.tar.gz                         php-7.4.19.tar.gz
apr-util-1.6.1.tar.gz  mysql-5.6.43-linux-glibc2.12-x86_64.tar.gz

解压mysql软件包

[root@jing src]# ls -la |grep mysql
-rw-r--r--.  1 root root 661214270 Jan 26 17:27 mysql-5.7.32-linux-glibc2.12-x86_64.tar.gz
[root@jing src]# tar -zxvf mysql-5.6.43-linux-glibc2.12-x86_64.tar.gz

把 mysql 安装包移动到 /usr/local/mysql 下

[root@jing src]# mv mysql-5.6.43-linux-glibc2.12-x86_64.tar.gz /usr/local/mysql/
[root@jing src]# cd /usr/local/mysql
[root@jing mysql]# pwd
/usr/local/mysql
[root@jing mysql]# ls
bin  docs  include  lib  LICENSE  man  README  share  support-files

建立 mysql 的用户

[root@jing mysql]# useradd -s /sbin/nologin mysql

建立存放数据的目录（用户组和用户设置为mysql）

[root@jing mysql]# mkdir -p /data/mysql ; chown -R mysql:mysql  /data/mysql
[root@jing mysql]# 
[root@jing mysql]# ls -la /data/mysql/
total 0
drwxr-xr-x. 2 mysql mysql  6 May 23 09:35 .
drwxr-xr-x. 3 root  root  19 May 23 09:35 ..

执行脚本（user=定义所属组，datadir=定义安装位置）

[root@jing mysql]# ./scripts/mysql_install_db --user=mysql --datadir=/data/mysql

-bash: ./scripts/mysql_install_db: No such file or directory
[root@jing mysql]# yum list |grep perl
下载Module模块
[root@jing mysql]# yum install -y perl-Module-Install

运行成功（出现两个OK）

[root@jing mysql]# ./scripts/mysql_install_db --user=mysql --datadir=/data/mysql     运行成功（出现两个OK）

修改配置文件

[root@jing mysql]# pwd
/usr/local/mysql
[root@jing mysql]# ls
bin      data  include  man     mysql-test  scripts  sql-bench
COPYING  docs  lib      my.cnf  README      share    support-files
[root@jing mysql]# cp support-files/
binary-configure     my-default.cnf       mysql-log-rotate     
magic                mysqld_multi.server  mysql.server         
[root@jing mysql]# cp support-files/my-default.cnf  /etc/my.cnf       拷贝配置文件
cp: overwrite ‘/etc/my.cnf’? y
[root@jing mysql]# vim  /etc/my.cnf   修改配置文件
 basedir = /usr/local/mysql   安装目录
 datadir = /data/mysql    存放数据的目录
 port = 3306     mysql默认端口
 server_id = 192.168.200。40     默认写为IP后三位/主机地址
 socket = /tmp/mysql.sock

拷贝启动脚本，修改启动脚本

[root@jing mysql]# cp support-files/mysql.server /etc/init.d/mysqld
basedir=/usr/local/mysql      和mysql配置文件对应
datadir=/data/mysql
[root@jing mysql]# chkconfig --add mysqld
[root@jing mysql]# chkconfig mysqld on
查看是否启动成功
[root@jing mysql]# service mysqld start
查看进程\端口
Starting MySQL.Logging to '/data/mysql/jing.err'.

[root@jing mysql]# ps -ef|grep mysqld

Apache安装

解压，切换目录，进行编译，make安装

[root@jing apr-1.6.5]# make && make install

报错

[root@jing apr-1.6.5]# ./configure --prefix=/usr/local/apr
1、configure: error: no acceptable C compiler found in $PATH错误主要是没有C编译器.
2、config.status: executing libtool commands    缺少libtool包，安装libtool 
rm: cannot remove 'libtoolT': No such file or directory     （此句可忽略）       
config.status: executing default commands

解决方法：
[root@jing apr-1.6.5]# cat config.log （可以不执行，自己感兴趣可以看一下）
[root@jing apr-1.6.5]# yum install -y gcc
[root@jing apr-1.6.5]# yum install -y libtool*
