wdcp安装常见问题

步骤

方法

修改 root 密码 执行命令sudo passwd root
输入密码 可以和 ubuntu 密码一致，也可以修改 (密码会让你输入两次)
修改 ssh 配置 执行命令sudo vi /etc/ssh/sshd_config
修 改 PermitRootLogin

进入 ssh 配置界面后找到PermitRootLogin，将它后面改为yes，保存

(按i进入编辑模式，编辑完esc退出，:w保存当前文件，:q退出)

重启 ssh 服务

执行命令sudo service ssh restart

ubuntu安装mysql报错，然后安装nginx报错，然后安装php报错，因为安装得是集成环境，LANMP。

报错如下：

configure in progress …
lib/mysql.sh: line 13: cmake: command not found

x86_64
—-Install Error: mysql configure err ———–

以下是所有报错的正确修复方案：

安装cmake：apt install cmake

切换到mysql目录下：cd /root/src/mysql-5.5.62/

删除文件：rm -f CMakeCache.txt

apt install libncurses5-dev

apt-get install libssl-dev

apt-get install libxml2

apt-get install libxml2-dev

apt-get install curl
apt-get install libcurl4-gnutls-dev

apt-get install libpng

apt-get install libpng-devel

apt-get install libjpeg-dev

apt-get install libpng-dev

apt-get install libxpm-dev

apt-get install libfreetype6-dev

apt-get install libt1-dev

apt-get install libmcrypt-dev

apt-get install libmysql++-dev

apt-get install libxslt1-dev

apt-get install autoconf

apt-get install gcc build-essential

继续执行：sh lanmp.sh

正确解决方案如上，而不是网上说的那一堆乱七八糟的，并不适用于ubuntu，反而会爆出更多的错误，linux各版本之间存在很多不一样的地方，不能一概而论的说是linux报错解决方案，只有对应系统的解决方案才是有用的。

sudo dpkg-reconfigure dash
　　运行后 选择no。
　　sudo sh lanmp.sh即可安装

安装nginx的时候出现

./configure: error: SSL modules require the OpenSSL library.
解决方法:
Centos需要安装openssl-devel
Ubuntu则需要安装:sudo apt-get install libssl-dev

Ubuntu
sudo apt-get install zlib1g-dev

+ ngx_http_echo_module was configured

checking for PCRE library … found

checking for PCRE JIT support … not found

checking for OpenSSL library … not found

./configure: error: SSL modules require the OpenSSL library.

You can either do not enable the modules, or install the OpenSSL library

into the system, or build the OpenSSL library statically from the source

with nginx by using –with-openssl= option.

解决办法：

sudo apt-get install openssl libssl-dev

cmake错误
安装g++和gcc 试试

在使用luarocks安装luasoap时，出现了expat.h: No such file or directory……的问题

在安装了libexpat1-dev之后解决

apt-get install libexpat1-dev
