LNMP Web服务搭建
mysql与php安装
1、JAVA Web环境（企业更多）
[tomcat(jvm)]、resin、jboss、Weblogic
配合nginx proxy_pass代理功能
2、Python Web环境
配合nginx uwsgi_pass代理功能
3、PHP Web环境（也会用，二三四五线）
配合nginx fastcgi_pass代理功能
4、GO 语言环境
数据库产品：
MySQL(mariadb)、Oracle、SQL SERVER、PGSQL
单机安装LNMP
先装数据库：
1.创建用户
[root@web02 ~]# useradd mysql -s /sbin/nologin -M
[root@web02 ~]# id mysql
uid=1002(mysql) gid=1002(mysql) 组=1002(mysql)
上传mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz
解压mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz
[root@web02 /server/tools]# tar xf mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz
[root@web02 /server/tools]# mv mysql-5.7.26-linux-glibc2.12-x86_64 /application/mysql-5.7.26
创建软连接
ln -s /application/mysql-5.7.26/ /application/mysql
2.卸载依赖包
rpm -e --nodeps mariadb-libs
3.编辑配置文件/etc/my.cnf
[root@web02 /server/tools]# vim /etc/my.cnf
[mysqld]
basedir = /application/mysql/
datadir = /application/mysql/data
socket = /tmp/mysql.sock
server_id = 1
port = 3306
log_error = /application/mysql/data/oldboy_mysql.err
[mysql]
socket = /tmp/mysql.sock
prompt = oldboy [\\d]>
4.初始化数据库
[root@web02 /server/tools]# rpm -qa mariadb-libs
[root@web02 /server/tools]# yum install libaio-devel -y
创建目录并授权
mkdir -p /application/mysql/data
chown -R mysql.mysql /application/mysql/
初始化
/application/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/application/mysql/ --datadir=/application/mysql/data
====
--user=mysql #<==mysql用户。
--basedir=/application/mysql/ #<==MySQL根目录。
--datadir=/application/mysql/data #<==MySQL数据文件目录。
--initialize-insecure #<==关闭MySQL安全策略，本书选择了关闭策略。
--initialize #<==开启MySQL安全策略，高安全环境采用。
5.配置MYSQL启动服务
[root@web02 /application/mysql/support-files]# vim /etc/systemd/system/mysqld.service
[Unit]
Description=MySQL Server by oldboy
Documentation=man:mysqld(8)
Documentation=http://dev.mysql.com/doc/refman/en/using-systemd.html
After=network.target
After=syslog.target
[Install]
WantedBy=multi-user.target
[Service]
User=mysql
Group=mysql
ExecStart=/application/mysql/bin/mysqld --defaults-file=/etc/my.cnf
LimitNOFILE = 5000
启动
[root@web02 /application/mysql/support-files]# systemctl start mysqld
[root@web02 /application/mysql/support-files]# systemctl enable mysqld
[root@web02 /application/mysql/support-files]# systemctl status mysqld
查看端口
[root@web02 /application/mysql/support-files]# netstat -lntup|grep mysql
查看进程
[root@web02 /application/mysql/support-files]# ps -ef|grep mysql|grep -v grep
6.配置环境变量登录
[root@web02 /application/mysql/support-files]# echo 'export PATH=/application/mysql/bin:$PATH' >>/etc/profile
[root@web02 /application/mysql/support-files]# tail -1 /etc/profile
[root@web02 /application/mysql/support-files]# . /etc/profile
[root@web02 /application/mysql/support-files]# echo $PATH
[root@web02 /application/mysql/support-files]# mysql

oldboy [(none)]>
7.如果出错 查看错误日志
日志文件 cat /application/mysql/data/oldboy_mysql.err
8.更改密码
mysqladmin -u root password 'oldboy123'
重新登录（交互式登录）
mysql -uroot -p
oldboy123
非交互登录：
mysql -uroot -poldboy123
====================================
编译安装PHP
1.安装PHP调用的库
yum install zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel -y
yum install freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel libxslt-devel -y
检查
rpm -qa zlib-devel libxml2-devel libjpeg-turbo-devel libiconv-devel
rpm -qa freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel
安装libiconv
cd /server/tools
上传libiconv-1.16.tar.gz
tar zxf libiconv-1.16.tar.gz
cd libiconv-1.16
./configure --prefix=/application/libiconv
make
make install
cd ../
yum install libmcrypt-devel -y
yum install mhash -y
yum install mcrypt -y
2.安装PHP
cd /server/tools
上传 php-7.3.5.tar.gz
tar xf php-7.3.5.tar.gz
cd php-7.3.5/
编译
./configure \
--prefix=/application/php-7.3.5 \
--enable-mysqlnd \
--with-mysqli=mysqlnd \
--with-pdo-mysql=mysqlnd \
--with-iconv-dir=/application/libiconv \
--with-freetype-dir \
--with-jpeg-dir \
--with-png-dir \
--with-zlib \
--with-libxml-dir=/usr \
--enable-xml \
--disable-rpath \
--enable-bcmath \
--enable-shmop \
--enable-sysvsem \
--enable-inline-optimization \
--with-curl \
--enable-mbregex \
--enable-fpm \
--enable-mbstring \
--with-gd \
--with-openssl \
--with-mhash \
--enable-pcntl \
--enable-sockets \
--with-xmlrpc \
--enable-soap \
--enable-short-tags \
--enable-static \
--with-xsl \
--with-fpm-user=nginx \
--with-fpm-group=nginx \
--enable-ftp \
--enable-opcache=no
检查
echo $? 为0
安装
make && make install
将nginx的用户和PHP的用户统一：nginx
[root@web02 /server/tools/php-7.3.5]# useradd nginx -u 1111 -s /sbin/nologin -M
[root@web02 /server/tools/php-7.3.5]# id nginx
uid=1111(nginx) gid=1111(nginx) 组=1111(nginx)
[root@web02 /server/tools/php-7.3.5]# vim /application/nginx/conf/nginx.conf
worker_processes 1;
user nginx nginx;
（编译的时候就改用nginx）
[root@web02 ~]# ln -s /application/php-7.3.5/ /application/php
3.配置php.ixi(PHP解析器配置文件)
[root@web02 ~]# cd /server/tools/php-7.3.5/
[root@web02 /server/tools/php-7.3.5]# ls php.ini-*
php.ini-development php.ini-production
[root@web02 /server/tools/php-7.3.5]# cp php.ini-development /application/php/lib/php.ini
4.配置php fpm
[root@web02 /server/tools/php-7.3.5]# cd /application/php/etc/
[root@web02 /application/php/etc]# ls
pear.conf php-fpm.conf.default php-fpm.d
[root@web02 /application/php/etc]# cp php-fpm.conf.default php-fpm.conf
[root@web02 /application/php/etc]# cd php-fpm.d/
[root@web02 /application/php/etc/php-fpm.d]# ls
www.conf.default
[root@web02 /application/php/etc/php-fpm.d]# cp www.conf.default www.conf
5.启动并检查端口
[root@web02 /application/php/etc/php-fpm.d]# /application/php/sbin/php-fpm
[root@web02 /application/php/etc/php-fpm.d]# netstat -lntup|grep php
tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 11257/php-fpm: mast
6.加入开机自启vim /etc/rc.local
/application/nginx/sbin/nginx
/application/php/sbin/php-fpm
7.配置nginx转发PHP请求
[root@web02 /application/nginx/conf]# vim extra/03_blog.conf
server {
listen 80;
server_name blog.etiantian.org;
location / {
root html/blog;
index index.html index.htm;
}
location ~ .*\.(php|php5)?$ {
root html/blog;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
}
编写测试文件
[root@web02 /application/nginx/conf]# echo "" > ../html/blog/test_info.php
[root@web02 /application/nginx/conf]# cat ../html/blog/test_info.php
[root@web02 /application/nginx/conf]# /application/php/bin/php
[root@web02 /application/nginx/conf]# nginx -t
[root@web02 /application/nginx/conf]# nginx -s reload
8、测试PHP连接mysql
[root@web02 /application/nginx/html/blog]# vim /application/nginx/html/blog/test_mysql.php
//$link_id=mysqli_connect('主机名','用户','密码');
$link_id=mysqli_connect('localhost','root','oldboy123') or mysql_error();
if($link_id){
echo "mysql successful by oldboy.\n";
}else{
echo mysql_error();
}
?>
[root@web02 /application/nginx/html/blog]# /application/php/bin/php /application/nginx/html/blog/test_mysql.php
mysql successful by oldboy.
LNMP环境搭建成功。
