N26-博客作业-week16

1、源码编译安装LNMP架构环境

IP:192.168.12.137
Nginx:1.8.1
MariaDB:5.5.57
PHP:5.6.31

安装开发环境包组
    yum groupinstall "Development Tools" "Server Platform Development" -y
安装开发程序包
    yum install pcre-devel -y

(1)安装nginx
# yum -y install openssl-devel zlib-devel

安装nginx
添加用户nginx,实现以之运行nginx服务进程:
# groupadd -r nginx
# useradd -r -g nginx nginx

# tar xf nginx-1.8.1.tar.gz
# cd nginx-1.8.1/
# ./configure \
  --prefix=/usr/local/nginx \
  --sbin-path=/usr/local/nginx/sbin/nginx \
  --conf-path=/etc/nginx/nginx.conf \
  --error-log-path=/var/log/nginx/error.log \
  --http-log-path=/var/log/nginx/access.log \
  --pid-path=/var/run/nginx/nginx.pid  \
  --lock-path=/var/lock/nginx.lock \
  --user=nginx \
  --group=nginx \
  --with-http_ssl_module \
  --with-http_flv_module \
  --with-http_stub_status_module \
  --with-http_gzip_static_module \
  --http-client-body-temp-path=/var/tmp/nginx/client/ \
  --http-proxy-temp-path=/var/tmp/nginx/proxy/ \
  --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ \
  --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi \
  --http-scgi-temp-path=/var/tmp/nginx/scgi \
  --with-pcre

为nginx提供SysV init脚本
#vim /etc/rc.d/init.d/nginx

#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig:   - 85 15 
# description:  Nginx is an HTTP(S) server, HTTP(S) reverse \
#               proxy and IMAP/POP3 proxy server
# processname: nginx
# config:      /etc/nginx/nginx.conf
# config:      /etc/sysconfig/nginx
# pidfile:     /var/run/nginx/nginx.pid
 
# Source function library.
. /etc/rc.d/init.d/functions
 
# Source networking configuration.
. /etc/sysconfig/network
 
# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0
 
nginx="/usr/local/nginx/sbin/nginx"
prog=$(basename $nginx)
 
NGINX_CONF_FILE="/etc/nginx/nginx.conf"
 
[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx
 
lockfile=/var/lock/subsys/nginx
 
make_dirs() {
   # make required directories
   user=`nginx -V 2>&1 | grep "configure arguments:" | sed 's/[^*]*--user=\([^ ]*\).*/\1/g' -`
   options=`$nginx -V 2>&1 | grep 'configure arguments:'`
   for opt in $options; do
       if [ `echo $opt | grep '.*-temp-path'` ]; then
           value=`echo $opt | cut -d "=" -f 2`
           if [ ! -d "$value" ]; then
               # echo "creating" $value
               mkdir -p $value && chown -R $user $value
           fi
       fi
   done
}
 
start() {
    [ -x $nginx ] || exit 5
    [ -f $NGINX_CONF_FILE ] || exit 6
    make_dirs
    echo -n $"Starting $prog: "
    daemon $nginx -c $NGINX_CONF_FILE
    retval=$?
    echo
    [ $retval -eq 0 ] && touch $lockfile
    return $retval
}
 
stop() {
    echo -n $"Stopping $prog: "
    killproc $prog -QUIT
    retval=$?
    echo
    [ $retval -eq 0 ] && rm -f $lockfile
    return $retval
}
 
restart() {
    configtest || return $?
    stop
    sleep 1
    start
}
 
reload() {
    configtest || return $?
    echo -n $"Reloading $prog: "
    killproc $nginx -HUP
    RETVAL=$?
    echo
}
 
force_reload() {
    restart
}
 
configtest() {
  $nginx -t -c $NGINX_CONF_FILE
}
 
rh_status() {
    status $prog
}
 
rh_status_q() {
    rh_status >/dev/null 2>&1
}
 
case "$1" in
    start)
        rh_status_q && exit 0
        $1
        ;;
    stop)
        rh_status_q || exit 0
        $1
        ;;
    restart|configtest)
        $1
        ;;
    reload)
        rh_status_q || exit 7
        $1
        ;;
    force-reload)
        force_reload
        ;;
    status)
        rh_status
        ;;
    condrestart|try-restart)
        rh_status_q || exit 0
            ;;
    *)
        echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
        exit 2
esac

为此脚本赋予执行权限:
# chmod +x /etc/rc.d/init.d/nginx

把Nginx加入系统变量
# cd /etc/profile.d/
# vim nginx.sh
# . nginx.sh 

添加至服务管理列表,并让其开机自动启动:
# chkconfig --add nginx
# chkconfig nginx on    

(1)安装MariaDB
# yum -y install ncurses-devel

安装cmake
# tar xf cmake-3.8.1.tar.gz 
# cd cmake-3.8.1/ 
# ./configure
# make -j 8 && make install

安装MariaDB
添加mysql运行组及用户、创建数据库数据文件文件夹并授予合适权限
# groupadd -r mysql
# useradd -r -g mysql mysql
# mkdir -p /data/mysql
# chown -R mysql:mysql /data/mysql

# tar xf mariadb-5.5.57.tar.gz
# cd mariadb-5.5.57/
# cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/data/mysql -DSYSCONFDIR=/etc
# make -j 8 && make install

备份原有mariadb配置文件
# mv /etc/my.cnf /etc/my.cnf.bak

初始化数据库,配置启动脚本
# cd /usr/local/mysql
# ./scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql
# ln -s /usr/local/mysql/my.cnf /etc/my.cnf
# cp ./support-files/mysql.server /etc/rc.d/init.d/mysqld
# vim /etc/rc.d/init.d/mysqld
basedir=/usr/local/mysql
datadir=/data/mysql
# chmod +x /etc/rc.d/init.d/mysqld
# chkconfig mysqld on
# service mysqld start

把MariaDB加入系统环境变量
# cd /etc/profile.d 
# vim mysql.sh
export PATH=/usr/local/mysql/bin:$PATH
# . mysql.sh

把MariaDB的库文件链接到系统默认的位置,在编译PHP等软件时可以不用指定其库文件地址
# ln -s /usr/local/mysql/lib/mysql /usr/lib/mysql
# ln -s /usr/local/mysql/include/mysql/ /usr/include/mysql
# mkdir /var/lib/mysql
# ln -s /tmp/mysql.sock /var/lib/mysql/mysql.sock

交互式设置数据库
# mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!
 
In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
 
Enter current password for root (enter for none):
OK, successfully used password, moving on...
 
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
 
Set root password? [Y/n] Y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
 ... Success!
 
 
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.
 
Remove anonymous users? [Y/n] Y
 ... Success!
 
Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.
 
Disallow root login remotely? [Y/n] Y
 ... Success!
 
By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.
 
Remove test database and access to it? [Y/n] Y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!
 
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
 
Reload privilege tables now? [Y/n] Y
 ... Success!
 
Cleaning up...
 
All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.
 
Thanks for using MariaDB!

(3)安装php
安装libmcrypt
# tar xf libmcrypt-2.5.7.tar.gz
# cd libmcrypt-2.5.7/
# ./configure
# make -j 8 && make install

include fastcgi_params;
}

测试php

# service nginx restart
# service php-fpm start
# cd /usr/local/nginx/html/
# vim index.php
<?php phpinfo(); ?>

2、编写一个脚本完成以下功能:
   (1)、一键搭建LNMP源码编译环境;
   (2)、可通过在脚本后面跟上一些参数来自定义安装目录等其他选项。
