LNMP安裝：centos7 + nginx + php7 + mysql5.6

1、nginx安裝

一、下載nginx並安裝依賴

nginx官網下載最新穩定版本（Stable version），http://nginx.org/en/download.html 。
cd /usr/local/src
wget http://nginx.org/download/nginx-1.12.1.tar.gz
tar -zxvf nginx-1.12.1.tar.gz

安裝依賴
yum -y install pcre-devel  openssl openssl-devel gcc gcc-c++ ncurses-devel perl

二、編譯安裝

cd /usr/local/src/nginx-1.12.1
./configure --prefix=/usr/local/nginx 
make && make install
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

開啓 nginx
/usr/local/nginx/sbin/nginx

2、php7安裝

一、安裝依賴包

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 epel-release autoconf m4

二、下載php源碼

php源碼下載地址：http://php.net/downloads.php
cd /usr/local/src
wget http://cn2.php.net/distributions/php-7.1.7.tar.gz
tar zxvf php-7.1.7.tar.gz
cd php-7.1.7

若服務器無nginx用戶與組，則添加 useradd nginx

三、編譯安裝

./configure \
--prefix=/usr/local/php \
--with-config-file-path=/etc \
--enable-fpm \
--with-fpm-user=nginx \
--with-fpm-group=nginx \
--enable-inline-optimization \

--enable-wddx \
--with-libxml-dir \
--with-xsl \
--enable-zip \
--enable-mysqlnd-compression-support \
--with-pear \
--enable-opcache

make && make install

編譯說明：--enable-gd-jis-conv \ 這個參數儘可能不要添加，否則gd生成圖片沒法插入中文。中文會被認爲是日文。詳見php官方bug https://bugs.php.net/bug.php?id=42218

四、配置

添加環境變量

vim /etc/profile 在末尾加入 
        PATH=$PATH:/usr/local/php/bin
        export PATH
執行 source /etc/profile  
這時候便可查看php版本  php -v

配置php-fpm(php版本爲7.x)

cd /usr/local/src/php-7.1.7
    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

配置php-fpm(php版本爲5.x)

cp /usr/local/src/php-5.6.29/php.ini-development /usr/local/php/lib/php.ini
cp  /usr/local/src/php-5.6.29/php.ini-production  /etc/php.ini
cp /usr/local/php/etc/php-fpm.conf.default  /usr/local/php/etc/php-fpm.conf
/usr/local/php/sbin/php-fpm

啓動php-fpm(php版本5.x 在前文中已經啓動，因此不須要再啓動)

/etc/init.d/php-fpm start

相關優化

查找php.ini位置   php -i |grep php.ini
一、修改 /etc/php.ini 的默認時間區域爲 date.timezone = PRC

修改參數後，記得重啓php-fpm

五、配置nginx與php

cd /usr/local/nginx/conf
vim nginx.conf
把php相關的註釋去掉
location ~ \.php$ {
            root           html;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
        }

重啓nginx
/usr/local/nginx/sbin/nginx -s reload

3、mysql5.6安裝

一、先檢查有無mariadb的包 #若爲centos7如下版本，則檢查mysql

rpm -qa|grep mariadb  
#若爲centos7如下版本 則rpm -qa|grep mysql
如有，則刪掉包及依賴 rpm -e  --nodeps mysql-libs-5.1.61-4.el6.x86_64

二、下載 解壓mysql

cd /usr/local/src
wget   http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.33-linux-glibc2.5-x86_64.tar.gz
tar zxvf mysql-5.6.33-linux-glibc2.5-x86_64
mv mysql-5.6.33-linux-glibc2.5-x86_64 ../mysql

三、在mysql目錄更改組和用戶，data目錄初始化

cd /usr/local/mysql
groupadd mysql
useradd -r -g mysql mysql
chown -R mysql:mysql ./

yum install -y perl-Module-Install.noarch  libaio*  #centos7如下版本，不需執行這一行命令

/usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
chown -R root ./
chown -R mysql data

四、複製配置文件

cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf

五、將mysqld服務加入開機自啓動項

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
經過chkconfig命令將mysqld服務加入到自啓動服務項中  chkconfig --add mysqld
檢查是否添加成功  chkconfig --list mysqld

六、開啓mysql

service mysqld start

七、鏈接mysql

/usr/local/mysql/bin/mysql

八、將mysql加入環境變量

vi /etc/profile
在文件最後加上2行代碼
MYSQL_HOME=/usr/local/mysql
export PATH=$PATH:$MYSQL_HOME/bin
再執行命令讓其生效  source /etc/profile
試試 mysql ，則能夠鏈接上數據庫

九、修改mysql密碼，並設置其可遠程鏈接數據庫

use mysql;
update user set Password=password('123456') where Host='localhost' and User='root';
delete from user where Password='';

設置用戶爲root密碼爲123456 的用戶，能夠遠程鏈接mysql
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
flush privileges;
