ubuntu 20.04上搭建LNMP环境的方法步骤（ubuntu20.04安装教程）

简单说明

由于之前是用Centos7搭建的，后来使用ubuntu 20.04的系统做为个人开发环境，所以想在ubuntu上也搭建一下环境，和Centos有一些小区别所以记录一下仅供学习。

安装前准备

下载软件： php：7.3.18 nginx：1.18.0 mariadb：10.5.4

解压文件：

tar zxf php-7.3.18.tar.gz tar zxf mariadb-10.5.4.tar.gz tar zxf nginx-1.18.0.tar.gz

安装Nginx

sudo groupadd -r nginx && sudo useradd -r -g nginx -s /sbin/nologin -d /usr/local/nginx nginx sudo apt install -y libpcre3-dev zlib1g-dev cd /home/allen/下载/nginx-1.18.0 ./configure --user=nginx --group=nginx make -j 4 && sudo make install sudo /usr/local/nginx/sbin/nginx -t #nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok #nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful sudo mv /usr/local/nginx/conf/nginx.conf /usr/local/nginx/conf/nginx.conf.back sudo vim /usr/local/nginx/conf/nginx.conf user nginx; worker_processes 4; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; log_format main '$remote_addr || $remote_user || $time_local || $request || $status || $body_bytes_sent || $http_referer || $http_user_agent || $http_x_forwarded_for'; include /data/www/*/*.conf; } sudo chown -R nginx:nginx /usr/local/nginx sudo vim /lib/systemd/system/nginx.service [Unit] Description=nginx After=network.target [Service] Type=forking ExecStart=/usr/local/nginx/sbin/nginx ExecReload=/usr/local/nginx/sbin/nginx -s reload ExecStop=/usr/local/nginx/sbin/nginx -s quit PrivateTmp=true [Install] WantedBy=multi-user.target sudo systemctl enable nginx #Created symlink /etc/systemd/system/multi-user.target.wants/nginx.service → /lib/systemd/system/nginx.service. reboot

重启后看看有没有启动成功

有一个错误：

configure: error: freetype-config not found.

解决办法： 据说：https://doopsky.com/ops/981.html

这是由于在 Ubuntu 19.04 中 apt-get 安装的 libfreetype6-dev 版本为 2.9.1-3 http://changelogs.ubuntu.com/changelogs/pool/main/f/freetype/freetype_2.9.1-3/changelog 在 changelog 中写到：

The `freetype-config' script is no longer installed by default (Closes: #871470, #886461). All packages depending on libfreetype6-dev should use pkg-config to find the relevant CFLAGS and libraries. freetype-config 被替代成 pkg-config ，新版本使用 pkg-config 管理 CFLAGS 和 库。

所以解决方法如下： 主要的思路就是用pkg-config代替freetype-config。安装pkg-config，我在上面已经安装了

cat ./configure | grep "freetype-config" -n 34847: if test -f "$i/bin/freetype-config"; then 34849: FREETYPE2_CONFIG="$i/bin/freetype-config" 34855: as_fn_error $? "freetype-config not found." "$LINENO" 5 36568: if test -f "$i/bin/freetype-config"; then 36570: FREETYPE2_CONFIG="$i/bin/freetype-config" 36576: as_fn_error $? "freetype-config not found." "$LINENO" 5 sed -i "s/freetype-config/pkg-config/g" ./configure

cat ./configure | grep "FREETYPE2_CONFIG --cflags" -n 34858: FREETYPE2_CFLAGS=`$FREETYPE2_CONFIG --cflags` 36579: FREETYPE2_CFLAGS=`$FREETYPE2_CONFIG --cflags` sed -i "s/FREETYPE2_CONFIG --cflags/FREETYPE2_CONFIG freetype2 --cflags/g" ./configure

cat ./configure | grep "FREETYPE2_CONFIG --libs" -n 34859: FREETYPE2_LIBS=`$FREETYPE2_CONFIG --libs` 36580: FREETYPE2_LIBS=`$FREETYPE2_CONFIG --libs` sed -i "s/FREETYPE2_CONFIG --libs/FREETYPE2_CONFIG freetype2 --libs/g" ./configure

cat ./ext/gd/config.m4 | grep "freetype-config" -n 188: if test -f "$i/bin/freetype-config"; then 190: FREETYPE2_CONFIG="$i/bin/freetype-config" 196: AC_MSG_ERROR([freetype-config not found.]) sed -i "s/freetype-config/pkg-config/g" ./ext/gd/config.m4

重新编译安装就OK
