本文主要介绍如何使用服务器的Linux实例手工搭建LNMP平台的web环境。
Linux实例手工部署LNMP环境具体操作步骤如下： 1.安装nginx 2.安装mysql 3.安装php 4.浏览器访问测试 操作步骤1.安装nginx
wget http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm rpm -ivh nginx-release-centos-7-0.el7.ngx.noarch.rpm yum -y install nginx systemctl start nginx systemctl enable nginx systemctl status nginx.service
使用浏览器访问 “http://服务器IP地址”，显示如下页面，说明nginx安装成功。
2.安装MySQL
wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm yum -y install mysql57-community-release-el7-10.noarch.rpm yum -y install mysql-community-server systemctl start mysqld systemctl enable mysqld systemctl status mysqld.service
执行以下命令，获取安装MySQL时自动设置的root用户密码。
grep 'temporary password' /var/log/mysqld.log
执行以下命令，并按照回显提示信息进行操作，加固MySQL。
mysql_secure_installation
Securing the MySQL server deployment. Enter password for user root: #输入上一步骤中获取的安装MySQL时自动设置的root用户密码 The existing password for the user account root has expired. Please set a new password. New password: #设置新的root用户密码 Re-enter new password: #再次输入密码 The 'validate_password' plugin is installed on the server. The subsequent steps will run with the existing configuration of the plugin. Using existing password for root. Estimated strength of the password: 100 Change the password for root ? ((Press y|Y for Yes, any other key for No) : N #是否更改root用户密码，输入N ... skipping. By default, a MySQL installation has an anonymous user, allowing anyone to log into MySQL without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? (Press y|Y for Yes, any other key for No) : Y #是否删除匿名用户，输入Y Success. Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? (Press y|Y for Yes, any other key for No) : Y #禁止root远程登录，输入Y Success. By default, MySQL comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? (Press y|Y for Yes, any other key for No) : Y #是否删除test库和对它的访问权限，输入Y - Dropping test database... Success. - Removing privileges on test database... Success. Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? (Press y|Y for Yes, any other key for No) : Y #是否重新加载授权表，输入Y Success. All done!
3.安装php
rpm -Uvh https://mirror.webtatic.com/yum/el7/epel-release.rpm rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm yum -y install php70w-tidy php70w-common php70w-devel php70w-pdo php70w-mysql php70w-gd php70w-ldap php70w-mbstring php70w-mcrypt php70w-fpm
执行以下命令，验证PHP的安装版本。
php -v
执行以下命令，启动PHP服务并设置开机自启动。
systemctl start php-fpm systemctl enable php-fpm
修改nginx配置文件以支持PHP。
vim /etc/nginx/nginx.conf
修改打开的“nginx.conf”文件。
找到server段落，修改或添加下列配置信息。
server {
listen 80;
listen [::]:80;
server_name _;
root /usr/share/nginx/html;
# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;
location / {
root /usr/share/nginx/html;
index index.php index.html index.htm; }
location ~ .php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param script_FILENAME /usr/share/nginx/html$fastcgi_script_name;
include fastcgi_params;
}
error_page 404 /404.html;
location = /404.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
执行以下命令，重新载入nginx的配置文件。
service nginx reload
浏览器访问测试。
在/usr/share/nginx/html/目录下创建“info.php”的测试页面
执行以下命令创建并打开“info.php”的测试文件
vim /usr/share/nginx/html/info.php
修改打开的“info.php”文件，将如下内容写入文件。
使用浏览器访问“http://服务器IP地址/info.php”，显示如下页面，说明环境搭建成功。
