LNMP介绍-MYSQL安装-php安装-nginx介绍

LNMP介绍：

 

MYSQL安装：

使用二进制免编译包（发布前编译后再打包）；为安装顺利可先使用yum安装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

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

#Data::Dumper

#则需先 yum -y install perl-Data-Dumper

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

#则需先 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 ; 定义basedir（mysql程序目录/usr/local/mysql）和datadir(/data/mysql)

chkconfig --add mysqld    #加入系统服务

/etc/init.d/mysqld start

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

 

php安装：

在lnmp里面php的安装和lamp的安装是有差异的。lnmp架构里php须要开启php-fpm服务，是一个独立的服务。

 

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

#先确保已安装：openssl-devel；libxml2-devel；bzip2-devel；libjpeg-turbo-devel；libpng-devel；freetype-devel；epel-release；php-mcrypt；libmcrypt-devel     这几个包

./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

#若报错：libtool: link: `ext/opcache/ZendAccelerator.lo' is not a valid libtool object；则执行make distclean   #从新初始化安装

ls /usr/local/php-fpm/sbin/php-fpm    #检查服务是否存在。

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文件并添加如下内容：

[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                        #检测php配置文件的语法是否有问题

 

Nginx介绍：

Nginx官网 nginx.org，最新版1.13，最新稳定版1.12

Nginx应用场景：web服务、反向代理、负载均衡

Nginx著名分支：淘宝基于Nginx开发的Tengine，使用上和Nginx同样，和Nginx的最大区别在于Tenging增长了一些定制化模块，在安全限速方面表现突出，支持对js，css合并

Nginx核心+lua相关的组件和模块组成了一个支持lua的高性能web容器openresty
