N25-第16周博客作業

1、源碼編譯安裝LNMP架構環境；

    安裝nginx：

     1）安裝依賴包

]# yum groupinstall "Development Tools" "Development Libraries" -y
]# yum install wget openssl-devel ncurses-devel cmake pcre-devel libxml2-devel bzip2-devel libcurl-devel libmcrypt-devel -y

     2）關閉防火墻和selinux

]# iptables -F
]# systemctl stop firewalld.service
]# systemctl disable firewalld.service
]# setenforce 0
]# sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/selinux/config

     3）創建nginx用戶和組

]# groupadd -r nginx
]# useradd -r -g nginx nginx

     4）編譯安裝nginx

]# tar xf nginx-1.6.1.tar.gz
]# cd nginx-1.6.1
]# ./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
]# make && make install

     5）啟動nginx

]# mkdir /var/tmp/nginx/client -p
]# echo "export PATH=/usr/local/nginx/sbin:$PATH" >/etc/profile.d/nginx.sh
]# source /etc/profile
]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
]# nginx

     安裝mysql：

    6）創建mysql用戶和組

]# groupadd -r mysql
]# useradd -g mysql -r -s /sbin/nologin -M -d /mydata/data mysql

     7）二進制方式安裝mysql

]# tar xf mysql-5.5.32.tar.gz
]# cd mysql-5.5.32
]# cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/mydata/data \
-DSYSCONFDIR=/etc \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock \
-DMYSQL_TCP_PORT=3306 \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DEXTRA_CHARSETS=all \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DMYSQL_USER=mysql \
-DWITH_DEBUG=0 \
-DWITH_SSL=system

     8）初始化數據庫

]# mkdir /mydata/data
]# chown -R mysql.mysql /mydata/data
]# cd /usr/local/mysql
]# scripts/mysql_install_db --user=mysql --datadir=/mydata/data/

     9）創建mysql參數文件

]# cp support-files/my-large.cnf /etc/my.cnf
]# vim /etc/my.cnf
[mysqld]
...
datadir= /mydata/data
innodb_file_per_table= ON
skip_name_resolve= ON
...

     10）創建啟動腳本

]# cp support-files/mysql.server /etc/rc.d/init.d/mysqld

     11）輸出mysql的頭文件至系統頭文件路徑/usr/include

]# ln -s /usr/local/mysql/include/ /usr/include/mysql

     12）輸出mysql的庫文件給系統庫查找路徑

]# echo "/usr/local/mysql/lib/" >/etc/ld.so.conf.d/mysql.conf
]# ldconfig 

    13）啟動mysql

]# echo "export PATH=/usr/local/mysql/bin:$PATH" >/etc/profile.d/mysql.sh
]# source /etc/profile
]# /etc/init.d/mysqld start

     安裝php：

    14）打補丁

]# tar xf php-5.4.4.tar.bz2
]# cd php-5.4.4
]# curl -o php-5.x.x.patch https://mail.gnome.org/archives/xml/2012-August/txtbgxGXAvz4N.txt
]# patch -p0 -b < ./php-5.x.x.patch

    15）編譯安裝php

./configure --prefix=/usr/local/php \
--with-mysql=/usr/local/mysql \
--with-openssl \
--enable-fpm \
--enable-sockets \
--enable-sysvshm \ 
--with-mysqli=/usr/local/mysql/bin/mysql_config \
--enable-mbstring \
--with-freetype-dir \
--with-jpeg-dir \
--with-png-dir \
--with-zlib-dir \
--with-libxml-dir=/usr \
--enable-xml \
--with-mhash \
--with-mcrypt \
--with-config-file-path=/etc \
--with-config-file-scan-dir=/etc/php.d \
--with-bz2 \
--with-curl 
]# make && make install

     16）創建php-fpm啟動腳本

]# cp sapi/fpm/init.d.php-fpm /etc/rc.d/init.d/php-fpm 
]# chmod +x /etc/rc.d/init.d/php-fpm 
]# chkconfig --add php-fpm
]# chkconfig php-fpm on
]# /etc/init.d/php-fpm start

     17）創建并修改php配置文件

]# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
]# vim /usr/local/php/etc/php-fpm.conf
pm.max_children = 150
pm.start_servers = 8
pm.min_spare_servers = 5
pm.max_spare_servers = 10
pid = /usr/local/php/var/run/php-fpm.pid

]# echo "fastcgi_param  SCRIPT_FILENAME    \$document_root\$fastcgi_script_name;" >> /etc/nginx/fastcgi_params

]# vim /etc/nginx/nginx.conf
location / {
            root   html;
            index  index.php index.html index.htm;
        } location ~ \.php$ {
            root           html;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
            include        fastcgi_params;
        }
]# nginx -s reload

     測試：

    18）測試nginx與php的聯動

]# cat > /usr/local/nginx/html/index.php << EOF
<?php
phpinfo();
?>
EOF

    19）測試php與mysql的聯動

]# cat >/usr/local/nginx/html/index.php <<EOF
<?php
    \$conn = mysql_connect('127.0.0.1','root','');
    if (\$conn)
        echo "OK";
    else
        echo "Failure";
?>
EOF

2、編寫一個腳本完成以下功能：
   (1)、一鍵搭建LNMP源碼編譯環境；

   (2)、可通過在腳本后面跟上一些參數來自定義安裝目錄等其他選項。

腳本執行前提：

1）操作系統版本為centos7

2）部署環境能夠訪問外網

3）源碼安裝包應提前準備好并與該腳本放在同一目錄下

#!/bin/bash
lnmp() {
echo "安裝前環境準備..."
sleep 3
yum remove nginx mysql mariadb php -y
rpm -ivh http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
yum groupinstall "Development Tools" "Development Libraries" -y
yum install openssl-devel \
ncurses-devel \
cmake \
pcre-devel \
libxml2-devel \
bzip2-devel \
libcurl-devel \
libmcrypt-devel -y

iptables -F
systemctl stop firewalld.service
systemctl disable firewalld.service
setenforce 0
sed -i '/^SELINUX\>/d' /etc/selinux/config
echo "SELINUX=disabled" >>/etc/selinux/config

echo "開始安裝nginx..."
sleep 3
