centos7下怎麼搭建lnmp？(需使用php7)

rt，阿里雲ecs主機，鏡像是CentOS 7.0 64位，網上教程太雜，且教程里都不是php7的版本，今天折騰一天還是沒裝好，卡在php fmp上，所以小白來這裡請教了。

阿里雲 centOS 7.2 PHP7 LNMP配置

作者:thinkcmf.com
經測試 騰訊雲CentOS7.2 已成功

更新系統軟體

yum update

安裝編譯工具:

yum install gcc automake autoconf libtool gcc-c++

安裝nginx

1. 安裝nginx源

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

2. 安裝nginx

yum install nginx

3. 啟動nginx

service nginx start

成功顯示:Redirecting to /bin/systemctl start nginx.service

4. 訪問http://你的ip/

如果成功安裝會出來nginx默認的歡迎界面

安裝MySQL5.7.*

1. 安裝mysql源

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

2. 安裝mysql

yum install mysql-community-server

確認一下mysql的版本，有時可能會提示mysql5.6

3. 安裝mysql的開發包，以後會有用

yum install mysql-community-devel

4. 啟動mysql

service mysqld start

成功返回Redirecting to /bin/systemctl start mysqld.service

5. 查看mysql啟動狀態

service mysqld status

出現pid證明啟動成功

6. 獲取mysql默認生成的密碼

$ grep "temporary password" /var/log/mysqld.log

2017-02-10T14:59:42.328736Z 1 [Note] A temporary password is generated for root@localhost: s/giN9Vo&>L9h
冒號後面的都是密碼(沒有空格) 複製就好

7. 換成自己的密碼

$ mysql -uroot -p
Enter password:輸入上面複製的密碼

8. 更換密碼

mysql&> ALTER USER "root"@"localhost" IDENTIFIED BY "MyNewPass4!";

這個密碼一定要足夠複雜，不然會不讓你改，提示密碼不合法

9. 退出mysql;

mysql&> quit;

10. 用新密碼再登錄，試一下新密碼

$ mysql -uroot -p
Enter password:輸入你的新密碼

11. 確認密碼正確後，退出mysql;

mysql&> quit;

編譯安裝php7.0.0

1. 下載php7源碼包

cd /root wget -O php7.tar.gz http://cn2.php.net/get/php-7.0.1.tar.gz/from/this/mirror

2. 解壓源碼包

源碼包的位置可以使用 find / -name php7 查找 並進入所在文件夾

tar -xvf php7.tar.gz

3. 打開解壓好的包

cd php-7.0.1

4. 安裝php依賴包

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. 編譯配置

(這一步可能我們會遇到很多configure error，我們一一解決，基本都是相關軟體開發包沒有安裝導致)

./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

--enable-shared
--enable-soap
--with-libxml-dir
--with-xmlrpc
--with-openssl

如有有出現錯誤可查找一下 (沒有發生過)

configure error:

1. configure: error: xml2-config not found. Please check your libxml2 installation.
解決：
$ yum install libxml2 libxml2-devel

2. configure: error: Cannot find OpenSSL"s &
解決：
$ yum install openssl openssl-devel

3. configure: error: Please reinstall the BZip2 distribution
解決：
$ yum install bzip2 bzip2-devel

4. configure: error: Please reinstall the libcurl distribution - easy.h should be in &/include/curl/
解決：
$ yum install libcurl libcurl-devel

5. If configure fails try --with-webp-dir=& configure: error: jpeglib.h not found.
解決：
$ 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.
解決：
$ 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.
解決：
$ yum install freetype freetype-devel

8. configure: error: Unable to locate gmp.h
解決：
$ yum install gmp gmp-devel

9. configure: error: mcrypt.h not found. Please reinstall libmcrypt.
解決：
$ yum install libmcrypt libmcrypt-devel

10. configure: error: Please reinstall readline - I cannot find readline.h
解決：
$ yum install readline readline-devel

11. configure: error: xslt-config not found. Please reinstall the libxslt &>= 1.1.0 distribution
解決：
$ yum install libxslt libxslt-devel


6. 編譯與安裝

make make install

這裡要make好久，要耐心一下

7. 添加 PHP 命令到環境變數

vim /etc/profile

在末尾加入

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


要使改動立即生效執行

source /etc/profile

查看環境變數

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.啟動php-fpm

/etc/init.d/php-fpm start
