Centos7 搭建lnmp环境 (centos7+nginx+MySQL5.7.9+PHP7)

一、挂载数据盘

df -h

只有系统盘了，挂载上原来的数据盘

fdisk -l

看到数据盘了/dev/vdb1

挂载上这个数据盘，

mkdir /data0

mount /dev/vdb1 /data0

然后写入分区：

echo ‘/dev/vdb1 /data0 ext4 defaults 0 0’ >> /etc/fstab
不写入分区表，重启后又要挂载的。

怎么知道分区类型是ext4，用这个命令：

df -hT

好的成功了！

如果不用磁盘，不用走第一步直接走下面安装！！！

二、安装nginx

首先更新系统软件

# yum update
安装nginx

1.安装nginx源

# yum localinstall http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
2.安装nginx

# yum install nginx
3.启动nginx

# service nginx start
Redirecting to /bin/systemctl start nginx.service

4.访问http://你的ip/

如果成功安装会出来nginx默认的欢迎界面

三、安装MySQL5.7.*

1.安装mysql源

# yum localinstall http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm
2.安装mysql

# yum install mysql-community-server
3.安装mysql的开发包，以后会有用

# yum install mysql-community-devel
4.启动mysql

# service mysqld start
Redirecting to /bin/systemctl start mysqld.service

5.查看mysql启动状态

# service mysqld status
出现pid

证明启动成功

6.获取mysql默认生成的密码

# grep ‘temporary password’ /var/log/mysqld.log

选中的就是密码。

7.换成自己的密码

# mysql -uroot -p
Enter password:输入上页的密码，进入mysql

8. 更换密码

1
mysql> ALTER USER ‘root’@‘localhost’ IDENTIFIED BY ‘MyNewPasdfs4!’;
这个密码一定要足够复杂，不然会不让你改，提示密码不合法;

9.退出mysql并试用下新密码

mysql> quit;

mysql -uroot -p
确认密码正确

四、编译安装php7.0.0

1.下载php7源码包

# cd /root & wget -O php7.tar.gz http://cn2.php.net/get/php-7.0.1.tar.gz/from/this/mirror
2.解压源码包

# tar -xvf php7.tar.gz
3.进入目录

# cd php-7.0.1
4.安装php依赖包

# yum install libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel
5.编译配置，这里如果上一步的某些依赖包没有安装好，就会遇到很多configure error，我们一一解决，安装上相关软件开发包就可以
# ./configure
–prefix=/usr/local/php
–with-config-file-path=/etc
–enable-fpm
–with-fpm-user=nginx
–with-fpm-group=nginx
–enable-inline-optimization
–disable-debug
–disable-rpath
–enable-shared
–enable-soap
–with-libxml-dir
–with-xmlrpc
–with-openssl
–with-mcrypt
–with-mhash
–with-pcre-regex
–with-sqlite3
–with-zlib
–enable-bcmath
–with-iconv
–with-bz2
–enable-calendar
–with-curl
–with-cdb
–enable-dom
–enable-exif
–enable-fileinfo
–enable-filter
–with-pcre-dir
–enable-ftp
–with-gd
–with-openssl-dir
–with-jpeg-dir
–with-png-dir
–with-zlib-dir
–with-freetype-dir
–enable-gd-native-ttf
–enable-gd-jis-conv
–with-gettext
–with-gmp
–with-mhash
–enable-json
–enable-mbstring
–enable-mbregex
–enable-mbregex-backtrack
–with-libmbfl
–with-onig
–enable-pdo
–with-mysqli=mysqlnd
–with-pdo-mysql=mysqlnd
–with-zlib-dir
–with-pdo-sqlite
–with-readline
–enable-session
–enable-shmop
–enable-simplexml
–enable-sockets
–enable-sysvmsg
–enable-sysvsem
–enable-sysvshm
–enable-wddx
–with-libxml-dir
–with-xsl
–enable-zip
–enable-mysqlnd-compression-support
–with-pear
–enable-opcache

如果报错，对应解决方法如下
configure error:

1.configure: error: xml2-config not found. Please check your libxml2 installation.

解决：

1
# yum install libxml2 libxml2-devel

2.configure: error: Cannot find OpenSSL’s

解决：

1
# yum install openssl openssl-devel

3.configure: error: Please reinstall the BZip2 distribution

解决：

1
# yum install bzip2 bzip2-devel

4.configure: error: Please reinstall the libcurl distribution - easy.h should be in /include/curl/

解决：

1
# yum install libcurl libcurl-devel

5.If configure fails try --with-webp-dir=

configure: error: jpeglib.h not found.

解决：

1
# yum install libjpeg libjpeg-devel
6.If configure fails try --with-webp-dir=

checking for jpeg_read_header in -ljpeg… yes

configure: error: png.h not found.

解决：

1
# yum install libpng libpng-devel

7.If configure fails try --with-webp-dir=

checking for jpeg_read_header in -ljpeg… yes

checking for png_write_image in -lpng… yes

If configure fails try --with-xpm-dir=

configure: error: freetype-config not found.

解决：

1
# yum install freetype freetype-devel
8.configure: error: Unable to locate gmp.h

解决：

1
# yum install gmp gmp-devel
9.configure: error: mcrypt.h not found. Please reinstall libmcrypt.

解决：

# yum install libmcrypt libmcrypt-devel

10.configure: error: Please reinstall readline - I cannot find readline.h

解决：

1
# yum install readline readline-devel
11.configure: error: xslt-config not found. Please reinstall the libxslt >= 1.1.0 distribution

解决：

1
# yum install libxslt libxslt-devel
6.编译与安装

# make && make install
这里要make好久，要耐心一下

7.添加 PHP 命令到环境变量

# vim /etc/profile
在末尾加入

PATH=$PATH:/usr/local/php/bin

export PATH

要使改动立即生效执行

# source /etc/profile
查看环境变量

# echo $PATH
查看php版本

# php -v
8.配置php-fpm

# cp php.ini-production /etc/php.ini

# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf

# cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf

# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm

# chmod +x /etc/init.d/php-fpm
9.启动php-fpm

# /etc/init.d/php-fpm start
五、配置nginx虚拟机,绑定域名

# vim /etc/nginx/conf.d/php7.aaa.com.conf
这里可以把php7.aaa.com.conf改成自己的域名
把下面的内容复制到php7.aaa.com.conf里

复制代码
server{
listen 80;
server_name php7.aaa.com;
root /var/www/html/php7.aaa.com; # 该项要修改为你准备存放相关网页的路径
location / {
index index.php index.html index.htm;
#如果请求既不是一个文件，也不是一个目录，则执行一下重写规则
if (!-e KaTeX parse error: Expected '}', got '#' at position 42: … { #̲地址作为将参数rewrite到… /index.php/KaTeX parse error: Expected 'EOF', got '#' at position 16: 1; #̲若是子目录则使用下面这句，将s… /subdir/index.php/$1;
}
}
#proxy the php scripts to php-fpm
location ~ .php {
include fastcgi_params;
##pathinfo支持start
#定义变量 $path_info ，用于存放pathinfo信息
set $path_info “”;
#定义变量 $real_script_name，用于存放真实地址
set $real_script_name KaTeX parse error: Expected 'EOF', got '#' at position 34: …e; #̲如果地址与引号内的正则表达式匹…fastcgi_script_name ~ “^(.+?.php)(/.+)$”) {
#将文件地址赋值给变量 $real_script_name
set $real_script_name $1;
#将文件地址后的参数赋值给变量 $path_info
set $path_info $2;
}
#配置fastcgi的一些参数
fastcgi_param SCRIPT_FILENAME $documen{t}_{r}oot$real_script_name;
fastcgi_param SCRIPT_NAME $real_script_name;
fastcgi_param PATH_INFO $path_info;
###pathinfo支持end
fastcgi_intercept_errors on;
fastcgi_pass 127.0.0.1:9000;
}

location ^~ /data/runtime {
return 404;
}

location ^~ /application {
return 404;
}

location ^~ /simplewind {
return 404;
}

}

2.重启nginx

# service nginx reload
3.

# vim /var/www/html/php7.aaa.com/index.php
把下面的代码复制到这个文件 里
