源码包安装LNMP

 21.由于初始化数据库没有设置密码，所以root密码为空，不安全，不推荐，设置一下密码

设置密码（推荐），注意此方法必须使用flush privileges拿令刷新一下权限才能生效

三、安装Nginx

1.创建运行nginx服务的用户 

[root@localhost ~]# useradd  --system -M -s /sbin/nologin  nginx

 2.解压pcre

[root@localhost src]# tar -zxvf pcre-8.41.tar.gz

3.配置pcre

[root@localhost pcre-8.41]# ./configure --prefix=/usr/local/pcre

4.编译并安装pcre

[root@localhost pcre-8.41]# make && make install

5.查看pcre版本

[root@localhost pcre-8.41]# pcre-config --version

8.41

6.安装nginx依赖包（Nginx依赖于pcre、zlib、openssl,在编译前配置时如果有问题
可以使用yum方式安装三个包pcre-devel、zlib-devel、openssl-devel）

[root@localhost src]# yum install -y pcre-devel zlib-devel openssl-devel

7.解压nginx

[root@localhost src]# tar -zxvf nginx-1.14.1.tar.gz

8.配置nginx编译环境

[root@localhost src]# cd nginx-1.14.1/

[root@localhost nginx-1.14.1]# ./configure --prefix=/usr/local/nginx --with-http_ssl_module

 编译环境配置完成如下图所示

9.编译安装nginx

[root@localhost nginx-1.14.1]# make&&make install

编译安装完成如下图所示

 10.修改nginx安装目录权限所有者

[root@localhost local]# chown -R nginx:nginx /usr/local/nginx/

 11.查看nginx安装目录结构

[root@localhost src]# cd nginx-1.14.1/
[root@localhost nginx-1.14.1]# cd /usr/local/nginx/
[root@localhost nginx]# tree

如下图所示

12.编辑nginx服务配置文件/usr/local/nginx/conf/nginx.conf ,修改nginx服务启动的默认用户为nginx

[root@localhost nginx]# vi /usr/local/nginx/conf/nginx.conf
#user nobody;
user nginx nginx;
worker_processes 1;

13.启动nginx

[root@localhost nginx]# /usr/local/nginx/sbin/nginx

14.查看nginx是否启动成功

[root@localhost nginx]# ps aux|grep nginx

15.查看nginx端口占用情况

[root@localhost nginx]# netstat -tlnp|grep nginx

16.防火墙放行80端口

[root@localhost nginx]# firewall-cmd --permanent --add-port=80/tcp
success
[root@localhost nginx]# firewall-cmd --reload

success

17.客户端浏览器访问服务器地址出现下图所示，表示己经安装成功了

 18.将nginx命令添加到环境变量，修改/etc/profile文件

export PATH=$PATH:/usr/local/mysql/bin:/usr/local/mysql/lib:/usr/local/nginx/sbin

更新配置文件：source /etc/profile

[root@localhost nginx]#source  /etc/profile

19.通过命令关闭 启动nginx

 a.启动nginx服务

[root@localhost nginx]# nginx

b.立刻停止nginx服务

[root@localhost nginx]# nginx -s stop

c.完成当前任务后停止nginx服务

[root@localhost nginx]# nginx -s quit

20.把nginx命令添加到系统服务

创建并编辑文件/etc/rc.d/init.d/nginx

[root@localhost nginx]# vim /etc/rc.d/init.d/nginx

#!/bin/bash
# nginx - this script starts and stops the nginx daemon
# chkconfig: - 85 15
# description: Nginx is an HTTP(S) server, HTTP(S) reverse
# proxy and IMAP/POP3 proxy server
# processname: nginx
# config: /etc/nginx/nginx.conf
# config: /usr/local/nginx/conf/nginx.conf
# pidfile: /usr/local/nginx/logs/nginx.pid
# Source function library.

# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0
nginx="/usr/local/nginx/sbin/nginx"
prog=$(basename $nginx)
NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf"
[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx
lockfile=/var/lock/subsys/nginx
make_dirs() {
# make required directories
user=`$nginx -V 2>&1 | grep "configure arguments:" | sed 's/[^*]*--user=([^ ]*).*/1/g' -`
if [ -z "`grep $user /etc/passwd`" ]; then
useradd -M -s /bin/nologin $user
fi
options=`$nginx -V 2>&1 | grep 'configure arguments:'`
for opt in $options; do
if [ `echo $opt | grep '.*-temp-path'` ]; then
value=`echo $opt | cut -d "=" -f 2`
if [ ! -d "$value" ]; then
# echo "creating" $value
mkdir -p $value && chown -R $user $value
fi
fi
done
}
start() {
[ -x $nginx ] || exit 5
[ -f $NGINX_CONF_FILE ] || exit 6
make_dirs
echo -n $"Starting $prog: "
daemon $nginx -c $NGINX_CONF_FILE

retval=$?
echo
[ $retval -eq 0 ] && touch $lockfile
return $retval
}
stop() {
echo -n $"Stopping $prog: "
killproc $prog -QUIT
retval=$?
echo
[ $retval -eq 0 ] && rm -f $lockfile
return $retval
}
restart() {
#configtest || return $?
stop
sleep 1
start
}
reload() {
#configtest || return $?
echo -n $"Reloading $prog: "
killproc $nginx -HUP
RETVAL=$?
echo
}
force_reload() {
restart
}
configtest() {
$nginx -t -c $NGINX_CONF_FILE
}
rh_status() {
status $prog
}
rh_status_q() {
rh_status >/dev/null 2>&1
}
case "$1" in
start)
rh_status_q && exit 0
$1
;;

stop)
rh_status_q || exit 0
$1
;;
restart|configtest)
$1
;;
reload)
rh_status_q || exit 7
$1

condrestart|try-restart)
rh_status_q || exit 0
;;
*)
echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
exit 2
esac

20.保存脚本并增加执行权限

[root@localhost nginx]# vim /etc/rc.d/init.d/nginx
[root@localhost nginx]# chmod 755 /etc/rc.d/init.d/nginx

21.通过系统服务命令管理nginx服务

[root@localhost nginx]# systemctl restart nginx

四、安装PHP服务

A、编译安装PHP依赖包libiconv

1.解压libiconv

[root@localhost src]# tar -zxvf libiconv-1.14.tar.gz

2.配置libiconv编译环境

[root@localhost src]# cd libiconv-1.14/
[root@localhost libiconv-1.14]# ./configure --prefix=/usr/local/libiconv

3.编译安装libiconv

[root@localhost libiconv-1.14]# make&&make install

编译过程中出现报错如下图

解决方法：编辑/usr/local/src/libiconv-1.14/srclib/stdio.h

将1010行的内容   _GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");

如下图所示

修改为：

#if defined(__GLIBC__)&&!defined(__UCLIBC__)&&!__GLIBC_PREREQ(2,16)
_GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");
#endif

如下图所示

 重新编译安装，安装成功如下图所示

 B、编译安装PHP依赖包libmcrypt

1、解压libmcrypt

[root@localhost src]# tar -zxvf libmcrypt-2.5.8.tar.gz

2、配置编译环境

[root@localhost src]# cd libmcrypt-2.5.8/
[root@localhost libmcrypt-2.5.8]# ./configure --prefix=/usr/local/libmcrypt

3、编译安装

[root@localhost libmcrypt-2.5.8]# make&&make install

安装完成，如下图所示

C、编译安装PHP依赖包mhash

mhash 是基于离散数学原理的不可逆向的 PHP 加密方式扩展库。mhash 可以用于创建校验数值，消息摘要，消息认证码，以及无须原文的关键信息保存（如密码）等。

[root@localhost src]# tar -zxvf mhash-0.9.9.9.tar.gz

配置mhash编译环境

[root@localhost mhash-0.9.9.9]# ./configure --prefix=/usr/local/mhash

编译安装
[root@localhost mhash-0.9.9.9]# make&&make install

安装完成如下图所示

D、编译安装PHP依赖包mcrypt

 mcryp是 PHP 里面重要的加密支持扩展库。mcrypt 库支持 20 多种加密算法和 8 种加密模式。mcrypt 要比 libmcrypt 功能更强大，在很多项目中必须使用 mcrypt 加密方式。在安装 mcrypt 之前，必须先正确安装 libmcrypt 和 mhash。

1解压安装包
[root@localhost src]# tar -zxvf mcrypt-2.6.8.tar.gz

2.配置编译环境

[root@localhost mcrypt-2.6.8]# ./configure --with-libmcrypt-prefix=/usr/local/libmcrypt --prefix=/usr/local/mcrypt

出现报错：You need at least libmhash 0.8.15,如下图所示

 解决方法如下：

[root@localhost mcrypt-2.6.8]# export LD_LIBRARY_PATH=/usr/local/libmcrypt/lib:/usr/local/mhash/lib
[root@localhost mcrypt-2.6.8]# export LDFLAGS="-L/usr/local/mhash/lib/ -I/usr/local/mhash/include/"
[root@localhost mcrypt-2.6.8]# export CFLAGS="-I/usr/local/mhash/include/"

 打开/etc/ld.so.conf，在文件之后，添加一行：/usr/local/lib，执行 ldconfig  ，重新编译即可

[root@localhost mcrypt-2.6.8]# vi /etc/ld.so.conf
[root@localhost mcrypt-2.6.8]# ldconfig

 3.编译安装

[root@localhost mcrypt-2.6.8]# make&&make install

五、配置PHP

1、安装PHP依赖包

[root@localhost src]# yum install -y php-mcrypt libmcrypt libmcrypt-devel php-pear libxml2 libxml2-devel curl curl-devel libjpeg libjpeg-devel libpng libpng-devel freetype-devel

2.解压php

[root@localhost src]# tar -zxvf php-7.1.24.tar.gz

3.配置php编译环境

[root@localhost src]# cd php-7.1.24/

[root@localhost php-7.1.24]# ./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --enable-fpm --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-iconv-dir --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-mbstring --with-mcrypt --enable-ftp --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --without-pear --with-gettext --disable-fileinfo --enable-maintainer-zts

4.编译安装php

[root@localhost php-7.1.24]# make&&make install

 5.配置php配置文件

[root@localhost php-7.1.24]# cp php.ini-production /usr/local/php/etc/php.ini

[root@localhost php-7.1.24]#ln -s /usr/local/php/etc/php.ini /etc/php.ini
[root@localhost php-7.1.24]# cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.conf

修改php服务启动的用户为nginx

[root@localhost php-7.1.24]# vi /usr/local/php/etc/php-fpm.conf

23 user = nginx
24 group = nginx

复制php启动脚本到/etc/init.d/

[root@localhost php-7.1.24]# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm

添加执行权限，将php服务加入到开机启动项

[root@localhost php-7.1.24]# chmod a+x /etc/init.d/php-fpm
[root@localhost php-7.1.24]# chkconfig --add php-fpm
[root@localhost php-7.1.24]# chkconfig php-fpm on

启动php服务

[root@localhost php-7.1.24]# service php-fpm start
Starting php-fpm done

查看php服务是否启动成功

[root@localhost php-7.1.24]# ps aux|grep php-fpm

 [root@localhost php-7.1.24]# netstat -tlnp|grep php-fpm

 编辑nginx配置文件，增加对index.php的支持

[root@localhost php-7.1.24]# vim /usr/local/nginx/conf/nginx.conf

44 location / {
45 root html;
46 index index.php index.html index.htm;
47 }

重启nginx服务

[root@localhost php-7.1.24]# service nginx restart
Restarting nginx (via systemctl): [ OK ]

编写php探测文件,查询nginx是否支持php

[root@localhost php-7.1.24]# echo "<?php phpinfo(); ?>" > /usr/local/nginx/html/index.php

客户端浏览器，访问服务端index.php报错，查看日志文件/usr/local/nginx/logs/error.log，报错如下

2020/07/01 11:00:54 [error] 95280#0: *7 open() "/usr/local/nginx/html/favicon.ico" failed (2: No such file or directory),

解决方法：

编辑nginx配置文件，去掉65~72行前面的注释，并修改70行脚本文件路径

[root@localhost logs]# vim /usr/local/nginx/conf/nginx.conf

66 location ~ .php$ {
67 root html;
68 fastcgi_pass 127.0.0.1:9000;
69 fastcgi_index index.php;
70 fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_na me;
71 include fastcgi_params;
72 }

重启nginx服务

[root@localhost nginx]# service nginx restart

再次通过客户端浏览器，访问服务端index.php页面正常如下图所示

 至此LNMP整个环境就搭建完成了
