一键脚本部署LNMP&论坛

        前一篇博客中，已有手动安装LNMP和论坛,为了更加方便快捷的安装服务，编写一键安装脚本如下：

#!/bin/bash
####关闭防火墙，关闭核心防护####
###试验环境：CentOS 7.6   Nginx 1.15   ###
echo "关闭防火墙,关闭核心防护"
systemctl stop firewalld
systemctl disable firewalld &> /dev/null
setenforce 0

###安装nginx####
nginx () {
yum install -y gcc gcc-c++ make pcre pcre-devel expat-devel perl zlib zlib-devel &> /dev/null
useradd -M -s /sbin/nologin nginx
cd /opt
tar zxvf nginx-1.15.9.tar.gz
cd nginx-1.15.9
echo " nginx正在编译安装"
./configure  --prefix=/usr/local/nginx  --user=nginx  --group=nginx  --with-http_stub_status_module &> /dev/null
make && make install  &> /dev/null
ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin

echo "

chmod 754 /lib/systemd/system/nginx.service

systemctl daemon-reload
systemctl start nginx
echo "正在启动nginx服务"
}

####安装mysql#####
mysql () {
cd /opt
yum -y install ncurses ncurses-devel bison cmake &> /dev/null
useradd -s /sbin/nologin mysql
