Centos7+nginx1.12+mysql5.7+php7环境安装
1.?下載nginx:http://nginx.org/en/download.html
?
?
2.?在usr/local文件夾中新建一個lnmp的文件夾，下載nginx壓縮包并解壓
[root@VM_48_141_centos ~]# cd usr/local
[root@VM_48_141_centos local]# mkdir lnmp
[root@VM_48_141_centos local]# cd lnmp
[root@VM_48_141_centos lnmp]# wget http://nginx.org/download/nginx-1.12.2.tar.gz
?
?[root@VM_48_141_centos nginx-1.12.2]# ./configure --prefix=/usr/local/lnmp/nginx
出錯
?
?
原因：沒有gcc的編譯庫
解決辦法：[root@VM_48_141_centos nginx-1.12.2]# yum install gcc gcc-c++ kernel-devel
?
繼續，又出錯
?
原因：沒有正則庫
?
解決辦法：[root@VM_48_141_centos nginx-1.12.2]# yum install pcre-devel
?
繼續，又出錯
?
原因：沒有zlib庫
?
解決辦法：?[root@VM_48_141_centos nginx-1.12.2]# yum install -y zlib-devel
?
?
繼續，OK
?
?
3.編譯并安裝 [root@VM_48_141_centos nginx-1.12.2]# make && make install
?
?
?
4啟動nginx
[root@VM_48_141_centos lnmp]# cd Nginx
進入剛才自定義的安裝目錄Nginx 有4個文件愛夾
conf:配置文件 ??html:網頁文件 ????logs:日志文件 ???sbin:主要進程文件
[root@VM_48_141_centos Nginx]# ./sbin/nginx
?
?
在瀏覽器中訪問：
?
?
?
關閉Nginx：[root@VM_48_141_centos Nginx]# kill -INT 28024
查看nginx主進程號：[root@VM_48_141_centos Nginx]# ps aux|grep nginx
?
中間用到的命令
grep 'nginx' /etc/group
awk -F":" '{print $1"\t\t"$4}' /etc/passwd | grep '1000'
Nginx.Conf

????#}
?
}
?
?
?
?
?
二.?安裝mysql
[root@VM_48_141_centos logs]# yum -y install mysql-server mysql mysql-devel
?
然后花了一下午在改mysql,裝的不是mysql，而是mariadb
?
1.卸載：yum autoremove ?mysql -y
?
2.wget https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm
?
?
3.yum localinstall mysql57-community-release-el7-11.noarch.rpm
?
?4.yum repolist enabled | grep "mysql.*-community.*"
?
5.yum install mysql-community-server -y
?
6. 啟動mysql并查看其狀態
命令：systemctl start mysqld
命令：systemctl status mysqld
?
7. 設置mysql為系統服務，隨系統啟動而啟動
命令：systemctl enable mysqld
命令：systemctl daemon-reload
?
8. 查看mysql下root賬號的默認密碼
mysql5.7安裝完成之后，在/var/log/mysqld.log文件中給root生成了一個默認密碼。通過下面的方式找到root默認密碼，然后登錄mysql。
命令：grep 'temporary password' /var/log/mysqld.log
其中Jb2h<%lp9itY部分就是默認密碼
9.2. 修改my.cnf文件(/etc/my.cnf)
9.2.1. 修改密碼策略
mysql的密碼策略分為三種：
0或LOW：Length
1或MEDIUM：Length; numeric, lowercase/uppercase, and special characters
2或STRONG：Length; numeric, lowercase/uppercase, and special characters; dictionary file
?
在mysql的配置文件my.cnf文件中增加如下設置
#如果不需要密碼策略，禁用密碼策略
validate_password = off
# 密碼選擇策略 0-LOW，1-MEDIUM，2-STRONG需要提供密碼字典文件
validate_password_policy = 0
9.2.2. 修改字符編碼為utf8
在my.cnf中的[mysqld]下增加如下配置
character_set_server = utf8
init_connect = 'SET NAMES utf8'
命令：systemctl restart mysqld
10. 登錄mysql
命令：mysql -uroot -p
輸入密碼：默認為剛才查到的Jb2h<%lp9itY
11. 修改密碼
命令：ALTER USER 'root'@'localhost' IDENTIFIED BY '12345678';
或命令：set password for 'root'@'localhost'=password('12345678');
12. 添加遠程賬戶
命令：GRANT ALL PRIVILEGES ON *.* TO 'remote'@'%' IDENTIFIED BY '12345678' WITH GRANT OPTION;
命令：FLUSH PRIVILEGES; 使設置生效
?
?
?
三．安裝PHP
1.?下載地址：http://cn2.php.net/distributions/php-7.1.11.tar.gz
?
?
?
?
?
wget http://cn2.php.net/distributions/php-7.1.11.tar.gz
tar -zxvf php-7.1.11.tar.gz
?
?
..安裝php依賴包
?yum install libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel
?
./configure --prefix=/usr/local/lnmp/PHP ?\--with-config-file-path=/etc \--enable-fpm \--with-fpm-user=nginx ?\--with-fpm-group=nginx \--enable-inline-optimization \--disable-debug \--disable-rpath \--enable-shared ?\--enable-soap \--with-libxml-dir \--with-xmlrpc \--with-openssl \--with-mcrypt \--with-mhash \--with-pcre-regex \--with-sqlite3 \--with-zlib \--enable-bcmath \--with-iconv \--with-bz2 \--enable-calendar \--with-curl \--with-cdb \--enable-dom \--enable-exif \--enable-fileinfo \--enable-filter \--with-pcre-dir \--enable-ftp \--with-gd \--with-openssl-dir \--with-jpeg-dir \--with-png-dir \--with-zlib-dir ?\--with-freetype-dir \--enable-gd-native-ttf \--enable-gd-jis-conv \--with-gettext \--with-gmp \--with-mhash \--enable-json \--enable-mbstring \--enable-mbregex \--enable-mbregex-backtrack \--with-libmbfl \--with-onig \--enable-pdo \--with-mysqli=mysqlnd \--with-pdo-mysql=mysqlnd \--with-zlib-dir \--with-pdo-sqlite \--with-readline \--enable-session \--enable-shmop \--enable-simplexml \--enable-sockets ?\--enable-sysvmsg \--enable-sysvsem \--enable-sysvshm \--enable-wddx \--with-libxml-dir \--with-xsl \--enable-zip \--enable-mysqlnd-compression-support \--with-pear \--enable-opcache
?
?
?
?
.編譯與安裝
# make && make install
這里要make好久，要耐心一下
?.添加 PHP命令到環境變量
# vim /etc/profile
在末尾加入
PATH=$PATH:/usr/local/php/bin
export PATH
要使改動立即生效執行
# source /etc/profile
查看環境變量
# echo $PATH
查看php版本
# php -v
配置php-fpm
# cp php.ini-production /etc/php.ini
# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
?
# cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf
# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
# chmod +x /etc/init.d/php-fpm
啟動php-fpm
# /etc/init.d/php-fpm start
?
.重啟nginx
# service nginx reload
<?php
phpinfo();
可以查看到如下信息
?
