LNMP介紹：

 

MYSQL安裝：

使用二進制免編譯包（發佈前編譯後再打包）；爲安裝順利可先使用yum安裝wget，perl-Data-Dumper，libaio

 

cd /usr/local/src

wget http://mirrors.163.com/mysql/Downloads/MySQL-5.6/mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz

tar zxvf mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz

mv mysql-5.6.39-linux-glibc2.12-x86_64 /usr/local/mysql

cd /usr/local/mysql

useradd mysql

mkdir /data/

./scripts/mysql_install_db --user=mysql --datadir=/data/mysql           #初始化

#若報FATAL ERROR: please install the following Perl modules before executing ./scripts/mysql_install_db:

#Data::Dumper

#則需先 yum -y install perl-Data-Dumper

#若報Installing MySQL system tables..../bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No #such file or directory

#則需先 yum -y install libaio

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（mysql程序目錄/usr/local/mysql）和datadir(/data/mysql)

chkconfig --add mysqld    #加入系統服務

/etc/init.d/mysqld start

#/usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf --user=mysql --datadir=/data/mysql &    #命令行方式啓動

 

php安裝：

在lnmp裏面php的安裝和lamp的安裝是有差異的。lnmp架構裏php須要開啓php-fpm服務，是一個獨立的服務。

 

useradd -s /sbin/nologin php-fpm

cd /usr/local/src

wget http://cn2.php.net/distributions/php-5.6.32.tar.gz

tar zxvf php-5.6.32.tar.gz

cd php-5.6.32

#先確保已安裝：openssl-devel；libxml2-devel；bzip2-devel；libjpeg-turbo-devel；libpng-devel；freetype-devel；epel-release；php-mcrypt；libmcrypt-devel     這幾個包

./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

#若報錯：libtool: link: `ext/opcache/ZendAccelerator.lo' is not a valid libtool object；則執行make distclean   #從新初始化安裝

ls /usr/local/php-fpm/sbin/php-fpm    #檢查服務是否存在。

cp /usr/local/src/php-5.6.30/php.ini-production  /usr/local/php-fpm/etc/php.ini    

vim /usr/local/php-fpm/etc/php-fpm.conf  #建立php-fpm.conf文件並添加如下內容：

[global]
pid = /usr/local/php-fpm/var/run/php-fpm.pid
error_log = /usr/local/php-fpm/var/log/php-fpm.log
[www]
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

cp /usr/local/src/php-5.6.30/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

/usr/local/php-fpm/sbin/php-fpm -t                        #檢測php配置文件的語法是否有問題

 

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同樣，和Nginx的最大區別在於Tenging增長了一些定製化模塊，在安全限速方面表現突出，支持對js，css合併

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
