源码部署lamt架构

lamt由apache，mysql，tomcat三者组成

1.准备工作

1.1.配置yum源，关闭防火墙和selinux

[root@tomcat ~]# rm -rf /etc/yum.repos.d/*
[root@tomcat ~]# curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo% Total    % Received % Xferd  Average Speed   Time    Time     Time  CurrentDload  Upload   Total   Spent    Left  Speed
100  2495  100  2495    0     0   2231      0  0:00:01  0:00:01 --:--:--  2231
[root@tomcat ~]# cat > /etc/yum.repos.d/server.repo << eof

[root@tomcat ~]# yum clean all
Updating Subscription Management repositories.
Unable to read consumer identity
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
12 files removed
[root@tomcat ~]# yum makecache//关闭防火墙和selinux
[root@note1 ~]# systemctl disable --now firewalld.service 
Removed /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@note1 ~]# setenforce 0

1.2.拉取相应源码包

[root@tomcat ~]# yum -y install wget vim
省略 . . .
[root@tomcat ~]# wget https://downloads.apache.org/apr/apr-1.7.4.tar.gz
[root@tomcat ~]# wget https://downloads.apache.org/apr/apr-util-1.6.3.tar.gz
[root@tomcat ~]# wget https://downloads.apache.org/httpd/httpd-2.4.57.tar.gz
[root@tomcat ~]# ls
anaconda-ks.cfg  apache-tomcat-9.0.80.tar.gz  apr-1.7.4.tar.gz  apr-util-1.6.3.tar.gz  httpd-2.4.57.tar.gz

2.安装apache

//安装依赖包
[root@tomcat ~]# yum -y install gcc gcc-c++ make pcre-devel openssl openssl-devel libtool expat-devel bzip2
省略 . . . //安装开发工具包
[root@tomcat ~]# yum groups mark install 'Development Tools'//创建apache服务的用户和组
[root@tomcat ~]# groupadd -r apache
[root@tomcat ~]# useradd -r -M -s /sbin/nologin -g apache apache//解压源码包

[root@tomcat apr-1.7.4]#//编译安装apr-1.7.4、apr-util-1.6.3、httpd-2.4.57
[root@tomcat apr-1.7.4]# ./configure --prefix=/usr/local/apr

访问apache页面

3.安装mariadb

使用yum命令安装mariadb

[root@tomcat ~]# yum -y install mariadb mariadb-server
[root@tomcat ~]# systemctl enable --now mariadb
Created symlink /etc/systemd/system/mysql.service → /usr/lib/systemd/system/mariadb.service.
Created symlink /etc/systemd/system/mysqld.service → /usr/lib/systemd/system/mariadb.service.
Created symlink /etc/systemd/system/multi-user.target.wants/mariadb.service → /usr/lib/systemd/system/mariadb.service.
[root@note1 ~]# mysql -e "set password = password('12345678');"//查看端口
[root@tomcat ~]# ss -antl
State          Recv-Q         Send-Q                   Local Address:Port                   Peer Address:Port         
LISTEN         0              128                            0.0.0.0:22                          0.0.0.0:*            
LISTEN         0              128                               [::]:22                             [::]:*

LISTEN         0              128                                  *:80                                *:*

4.安装tomcat

//安装依赖包
[root@tomcat ~]# dnf -y install java-17-openjdk java-17-openjdk-devel//查看安装的版本，能够查看到版本则说明安装成功
[root@tomcat ~]# java --version
openjdk 17.0.1 2021-10-19 LTS
OpenJDK Runtime Environment 21.9 (build 17.0.1+12-LTS)
OpenJDK 64-Bit Server VM 21.9 (build 17.0.1+12-LTS, mixed mode, sharing)//解压源码包至指定目录
[root@tomcat ~]# tar xf apache-tomcat-9.0.80.tar.gz -C /usr/local/
[root@tomcat ~]# cd /usr/local/ && ls
apache                apr        apr-util        bin  games         include  lib64    sbin   src
apache-tomcat-9.0.80  apr-1.7.4  apr-util-1.6.3  etc  httpd-2.4.57  lib      libexec  share//设置tomcat软链接，方便后续如果更换tomcat版本后也能直接使用

访问tomcat的web页面

启用httpd的代理模块

[root@tomcat ~]# sed -i '/proxy_module/s/#//g' /usr/local/apache/conf/httpd.conf
[root@tomcat ~]# sed -i '/proxy_fcgi_module/s/#//g' /usr/local/apache/conf/httpd.conf
[root@tomcat ~]# sed -i '/proxy_connect_module/s/#//g' /usr/local/apache/conf/httpd.conf
[root@tomcat ~]# sed -i '/proxy_http_module/s/#//g' /usr/local/apache/conf/httpd.conf

配置虚拟主机

[root@tomcat ~]# vim /usr/local/apache/conf/httpd.conf
[root@tomcat ~]# tail -13 /usr/local/apache/conf/httpd.conf
SSLRandomSeed connect builtin
</IfModule><VirtualHost *:80>DocumentRoot "/usr/local/apache/htdocs"ProxyPass / http://192.168.195.133:8080/ProxyPassReverse / http://192.168.195.133:8080/<Directory "/usr/local/apache/htdocs">Options noneAllowOverride noneRequire all granted</Directory>
