一、LNMP架构介绍

       LNMP代表的就是：Linux系统下Nginx+MySQL+PHP这种网站服务器架构。Nginx中的PHP是以fastcgi的方式结合Nginx的，可以理解为Nginx代理了PHP的fastcgi。和LAMP不同的是，提供web服务的是Nginx并且php是作为一个独立服务存在的，这个服务叫做php-fpm，Nginx直接处理静态请求，动态请求会转发给php-fpm。

二、准备工作

1、将安装包传到/opt/目录下

nignx安装包：nginx-1.12.2.tar.gz

mysql安装包：mysql-boost-5.7.20.tar.gz

php安装包：php-7.1.10.tar.bz2

Discuz论坛安装包：Discuz_X3.4_SC_UTF8.zip

2、搭建本地yum仓库

mount /dev/sr0 /mnt/
  
cd /etc/yum.repos.d/
mkdir bak
mv *.repo bak
vim local.repo
[local]
name=local
baseurl=file:///mnt
gpgcheck=0
  
yum clean all && yum makecache

三、编译安装nginx服务

编译安装过程前一篇博客已详细写过，这里写一个一键安装nginx服务的脚本

vim nginx.sh

#!/bin/bash
echo "请先将软件包上传到opt目录下（nginx-1.12.2.tar.gz）"
read -p "请问安装包是否都上传到opt目录下(yes/no)" A
if [ $A == yes ]
then
echo "开始部署"
else 
echo "请将软件包先上传到opt目录下"
exit
fi
####防火墙核心防护关闭
systemctl stop firewalld 
setenforce 0
####安装依赖环境
yum -y install openssl openssl-devel gcc gcc-c++ pcre-devel zlib-devel make &> /dev/null
if [ $? -eq 0 ]
then
echo "依赖环境安装完成"
else
echo "请检查网络环境"
exit 0
fi
echo "创建运行用户、组"
useradd -M -s /sbin/nologin nginx
echo "编译安装Nginx"
cd /opt
 
tar zxvf nginx-1.12.2.tar.gz -C /opt/ &> /dev/null
echo "解压完成"
cd nginx-1.12.2/
echo "wait..."
./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module &> /dev/null
echo "编译安装时间较长，请等待。。。"
make -j2 && make install &> /dev/null
 
echo "Nginx安装完成"
echo "路径优化"
ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/
 
echo "检查配置文件"
nginx -t
 
echo "启动Nginx"
nginx
 
echo "查看版本"
nginx -V
 
 
 
echo "升级Nginx"
 
echo "请稍等"
cd /opt
tar -zxvf nginx-1.22.1.tar.gz
 
cd nginx-1.22.1/
./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module \
--with-http_ssl_module &> /dev/null
 
make -j2 
 
mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx_old
 
cp -p /opt/nginx-1.22.1/objs/* /usr/local/nginx/sbin/
 
echo "重启服务"
systemctl restart nginx
 
echo "查看版本"
nginx -V

四、编译安装mysql服务

编译安装过程之前博客已详细写过，这里写一个一键安装mysql服务的脚本

vim mysql.sh

#!/bin/bash
 
echo "安装MySQL服务"
echo "wait..."
yum -y install \
ncurses \
ncurses-devel \
bison \
cmake &> /dev/null
 
#创建运行用户
useradd -s /sbin/nologin  mysql
#编译安装
cd /opt
tar xzvf mysql-boost-5.7.20.tar.gz &> /dev/null
cd /opt/mysql-5.7.20/
echo "wait..."
cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \
-DSYSCONFDIR=/etc \
-DSYSTEMD_PID_DIR=/usr/local/mysql \

-DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DWITH_BOOST=boost \
-DWITH_SYSTEMD=1 &> /dev/null
echo "wait..."
make -j2 && make install &> /dev/null
#数据库目录进行权限调整
chown -R mysql:mysql /usr/local/mysql/
#调整配置文件
 
echo '[client]
port = 3306
default-character-set=utf8

[mysql]

' > /etc/my.cnf
 
chown mysql:mysql /etc/my.cnf
#设置环境变量

cp usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/
 
#数据库开启
systemctl start mysqld
systemctl enable mysqld
netstat -anpt | grep 3306
 
yum -y install expect &> /dev/null
source /etc/profile
#设置Mysql密码
/usr/bin/expect <<-EOF
spawn mysqladmin -u root -p password  
expect {
"Enter password"
{send "\r";exp_continue}
"New password"
{send "abc123\r";exp_continue}
"Confirm new password"
{send "abc123\r"}
}
expect eof
EOF

五、编译安装 PHP 解析环境

编译安装过程之前博客已详细写过，这里写一个一键安装PHP解析的脚本

vim php.sh

#!/bin/bash
 
yum -y install \
gd \
libjpeg libjpeg-devel \
libpng libpng-devel \
freetype freetype-devel \
libxml2 libxml2-devel \
zlib zlib-devel \
curl curl-devel \
openssl openssl-devel
 
cd /opt
tar jxvf php-7.1.10.tar.bz2
cd /opt/php-7.1.10/
 
./configure \
--prefix=/usr/local/php7 \
--with-apxs2=/usr/local/httpd/bin/apxs \
--with-mysql-sock=/usr/local/mysql/mysql.sock \
--with-config-file-path=/usr/local/php7 \
--with-mysqli \
--with-zlib \
--with-curl \
--with-gd \
--with-jpeg-dir \
--with-png-dir \
--with-freetype-dir \
--with-openssl \
--enable-mbstring \
--enable-xml \
--enable-session \
--enable-ftp \
--enable-pdo \
--enable-tokenizer \
--enable-zip
 
 
make -j 4 && make install
 
cp /opt/php-7.1.10/php.ini-development /usr/local/php7/php.ini
#在测试环境时使用php.ini-development文件，而在生产环境时使用php.ini-production文件
 
sed -i.bak -e "1170 s|.*|mysqli.default_socket = /usr/local/mysql/mysql.sock|" -e "939 s|.*|date.timezone = Asia/Shanghai|" /usr/local/php7/php.ini
 
ln -s /usr/local/php7/bin/* /usr/local/bin/
 
sed -i.bak -e "255 s/.*/DirectoryIndex index.html index.php/" -e "393c AddType application/x-httpd-php .php\nAddType application/x-httpd-php-source .phps" /etc/httpd.conf
 
rm -rf /usr/local/httpd/htdocs/index.html
echo "
phpinfo();
?>" > /usr/local/httpd/htdocs/index.php
 
systemctl restart httpd.service
 
/usr/bin/expect <<EOF
spawn mysql -u root -p
 
expect "Enter password" {send "abc123\r"}
expect "mysql" {send "CREATE DATABASE bbs;\r"}
expect "mysql" {send "GRANT all ON bbs.* TO 'bbsuser'@'%' IDENTIFIED BY 'admin123';\r"}
expect "mysql" {send "flush privileges;\r"}
expect "mysql" {send "quit\r"}
 
expect eof
EOF
 
unzip /opt/Discuz_X3.4_SC_UTF8.zip -d /opt/dis
cd /opt/dis/dir_SC_UTF8/
cp -r upload/ /usr/local/httpd/htdocs/bbs
cd /usr/local/httpd/htdocs/bbs
chown -R daemon ./config
chown -R daemon ./data
chown -R daemon ./uc_client
chown -R daemon ./uc_server/data

六、 部署Discuz社区论坛

写一个一键部署Discuz社区论坛的脚本：

vim discuz.sh

#!/bin/bash
 
cd /opt
unzip Discuz_X3.4_SC_UTF8.zip  -d /tmp 
cd /tmp/dir_SC_UTF8/
cp -r upload/ /usr/local/nginx/html/bbs/
cd /usr/local/nginx/html/bbs/
chown -R root:nginx ./config/
chown -R root:nginx ./data/
chown -R root:nginx ./uc_client/
chown -R root:nginx ./uc_server/
 
chmod -R 777 ./config/
chmod -R 777 ./data/
chmod -R 777 ./uc_client/
chmod -R 777 ./uc_server/

七、装完后使用浏览器访问
