Nginx一键部署安装脚本

因为海天有个服务器只需要nginx做大理，就不需要使用lnmp安装一整套内容了，于是网上找到了这个nginx的一键安装脚本，可完成Nginx的全自动编译安装。

#!/bin/bash
ck_ok()
{
if [ $? -ne 0 ]
then
echo "$1 error."
exit 1
fi
}

download_ng()
{
cd /usr/local/src
if [ -f nginx-1.23.0.tar.gz ]
then
echo "当前目录已经存在nginx-1.23.0.tar.gz"
echo "检测md5"
ng_md5=`md5sum nginx-1.23.0.tar.gz|awk '{print $1}'`
if [ ${ng_md5} == 'e8768e388f26fb3d56a3c88055345219' ]
then
return 0
else
sudo /bin/mv nginx-1.23.0.tar.gz nginx-1.23.0.tar.gz.old
fi
fi

sudo curl -O http://nginx.org/download/nginx-1.23.0.tar.gz
ck_ok "下载Nginx"
}
install_ng()
{
cd /usr/local/src
echo "解压Nginx"
sudo tar zxf nginx-1.23.0.tar.gz
ck_ok "解压Nginx"
cd nginx-1.23.0

echo "安装依赖"
if which yum >/dev/null 2>&1
then
## RHEL/Rocky
for pkg in gcc make pcre-devel zlib-devel openssl-devel
do
if ! rpm -q $pkg >/dev/null 2>&1
then
sudo yum install -y $pkg
ck_ok "yum 安装$pkg"
else
echo "$pkg已经安装"
fi
done
fi

if which apt >/dev/null 2>&1
then
##ubuntu
for pkg in make libpcre++-dev libssl-dev zlib1g-dev
do
if ! dpkg -l $pkg >/dev/null 2>&1
then
sudo apt install -y $pkg
ck_ok "apt 安装$pkg"
else
echo "$pkg已经安装"
fi
done
fi

echo "configure Nginx"
sudo ./configure --prefix=/usr/local/nginx --with-http_ssl_module
ck_ok "Configure Nginx"

echo "编译和安装"
sudo make && sudo make install
ck_ok "编译和安装"

echo "编辑systemd服务管理脚本"

echo "加载服务"
sudo systemctl unmask nginx.service
sudo systemctl daemon-reload
sudo systemctl enable nginx
echo "启动Nginx"
sudo systemctl start nginx
ck_ok "启动Nginx"
}

download_ng
install_ng

将脚本保存为nginx_install.sh，执行以下命令：

chmod +x nginx_install.sh && ./nginx_install.sh

即完成nginx的安装部署。

常用nginx命令：

# 启动nginx
service nginx start
# 停止nginx
service nginx stop
# 设置开机启动
service nginx enable
# 取消开机启动
service nginx disable
