12.2 MySQL 安裝
《 MySQL 安裝》
(1)下載 Mysql，解壓，挪動，
移除之前的LAMP的mysql
rm -rf /usr/local/mysql
rm -rf /etc/init.d/mysqld
cd /usr/local/src
wget http://mirrors.sohu.com/mysql/MySQL-5.6/mysql-5.6.36-linux-glibc2.5-x86_64.tar.gz
tar zxvf mysql-5.6.36-linux-glibc2.5-x86_64.tar.gz
mv mysql-5.6.36-linux-glibc2.5-x86_64 /usr/local/mysql
useradd mysql
mkdir /data/
./scripts/mysql_install_db --user=mysql --datadir=/data/mysql
cp support-files/my-default.cnf? /etc/my.cnf
cp support-files/mysql.server /etc/init.d/mysqld
vim /etc/init.d/mysqld
定義basedir和datadir
basedir= /usr/local/mysql
datadir=/data/mysql
啟動mysql
/etc/init.d/mysqld start
加入開機系統服務
chkconfig?--add?mysqld?
chkconfig??mysqld? on
service mysqld start
service mysqld stop
12.3 PHP 安裝(上)
12.4 PHP 安裝(下)
和LAMP安裝PHP方法有差別，需要開啟php-fpm服務
cd /usr/local/src/
wget http://cn2.php.net/distributions/php-5.6.30.tar.gz
tar zxf php-5.6.30.tar.gz
useradd -s /sbin/nologin php-fpm 添加用戶
cd php-5.6.30
make clean 清掉之前的配置
yum install -y libcurl-devel 安裝包
./configure --prefix=/usr/local/php-fpm --with-config-file-path=/usr/local/php-fpm/etc --enable-fpm --with-fpm-user=php-fpm --with-fpm-group=php-fpm --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-pdo-mysql=/usr/local/mysql --with-mysql-sock=/tmp/mysql.sock --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-ftp --enable-mbstring --enable-exif --with-pear --with-curl? --with-openssl
make && make install
cp php.ini-production /usr/local/php-fpm/etc/php.ini
cd /usr/local/php-fpm/etc/
vim /usr/local/php-fpm/etc/php-fpm.conf //寫入如下內容，（參考https://coding.net/u/aminglinux/p/aminglinux-book/git/blob/master/D15Z/php-fpm.conf）
[global]
pid = /usr/local/php-fpm/var/run/php-fpm.pid
error_log = /usr/local/php-fpm/var/log/php-fpm.log
[www] #模塊c池子名字
listen = /tmp/php-fcgi.sock
listen.mode = 666
user = php-fpm
group = php-fpm
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024
拷貝啟動腳本
cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
chmod 755 /etc/init.d/php-fpm
chkconfig --add php-fpm
chkconfig php-fpm on
service php-fpm start
ps aux |grep php-fpm
12.5 Nginx 介紹
Nginx官網 nginx.org，最新版1.13，最新穩定版1.12
Nginx應用場景：web服務、反向代理、負載均衡
Nginx著名分支，淘寶基於Nginx開發的Tengine，使用上和Nginx一致，服務名，配置文件名都一樣，和Nginx的最大區別在於Tenging增加了一些定制化模塊，在安全限速方面表現突出，另外它支持對js，css合並
Nginx核心+lua相關的組件和模塊組成了一個支持lua的高性能web容器openresty，參考http://jinnianshilongnian.iteye.com/blog/2280928
12.6 Nginx 安裝
cd /usr/local/src
wget http://nginx.org/download/nginx-1.12.1.tar.gz
tar zxf nginx-1.12.1.tar.gz
cd /usr/local/src/nginx-1.12.1
./configure --prefix=/usr/local/nginx
make && ?make install
vim /etc/init.d/nginx //復制如下內容（參考https://coding.net/u/aminglinux/p/aminglinux-book/git/blob/master/D15Z/etc_init.d_nginx ）

curl localhost #默認虛擬主機
測試php解析
vim /usr/local/nginx/html/1.php
寫入 <?php
