lnmp安装

下载安装包：
nginx: wget https://nginx.org/download/nginx-1.9.9.tar.gz
php: wget https://www.php.net/distributions/php-7.4.16.tar.gz
mysql: wget https://downloads.mysql.com/archives/get/p/23/file/mysql-5.7.33.tar.gz
升级apt库: apt-get update
nginx安装：
1、解压安装包　tar -xzvf nginx-1.9.9.tar.gz 　＆　 cd nginx-1.9.9
２、./configure --prefix=/usr/local/nginx
３、make

可能出现的错误
./configure: error: C compiler cc is not found

解决方案：
sudo apt install build-essential  该命令将安装包括gcc，g ++和make。gcc --version 验证是否安装成功

./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.

解决方案：sudo apt install  libpcre3 libpcre3-dev

./configure: error: the HTTP gzip module requires the zlib library.
You can either disable the module by using --without-http_gzip_module
option, or install the zlib library into the system, or build the zlib library
statically from the source with nginx by using --with-zlib=<path> option.

 解决方案：
        wget http://www.zlib.net/zlib-1.2.11.tar.gz 
        tar -xzvf zlib-1.2.11.tar.gz
        cd zlib-1.2.11
        ./configure
        make && make install

make[1]: 离开目录“/home/yinhuakai/soft/nginx-1.9.9”
make: *** [Makefile:8：build] 错误 2

解决方案：vim objs/Makefile，去掉CFLAGS中的-Werror，再重新make。(Werror 要求gcc将所有的警告当成错误进行处理)
解决方案２：vim src/os/unix/ngx_user.c　注释该代码片段/* cd.current_salt[0] = ~salt[0];*/

4、make install

cd nginx(cd /usr/local/nginx/sbin )命令：
./nginx 启动
./nginx -s stop 关闭
./nginx -s quit 优雅不安比
./nginx -s reload　重新加载配置文件
./nginx -s reopen　　　重新打开日志
./nginx -t　　检查nginx配置文件是否报错
在/etc/init.d/中创建nginx脚本（代码如下）　使用sysv-rc-conf --add nginx （添加到服务列表）;sysv-rc-conf nginx on;（开启自动启动）

sysv-rc-conf　命令安装：
１、如果sysv-rc-conf安装失败，则 vim /etc/apt/sources.list 在文件末尾添加：deb http://archive.ubuntu.com/ubuntu/ trusty main universe restricted multiverse
２、apt-get update
３、apt-get install sysv-rc-conf

５、sysv-rc-conf nginx　将nginx 加入到服务列表
６、sysv-rc-conf on nginx 　　设置nginx开机启动
mysql安装：

安装前准备
apt install cmake
wget http://www.sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz
tar -xzvf boost_1_59_0.tar.gz
mkdir -p /usr/local/boost

注：
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql 设置安装目录
-DMYSQL_DATADIR=/home/mysqlData 设置数据库存放目录
-DMYSQL_UNIX_ADDR=/home/mysqlData/mysql.sock 设置UNIX socket 目录
-DMYSQL_USER=mysql 设置运行用户
-DDEFAULT_CHARSET=utf8 设置默认字符集，默认latin1
-DEFAULT_COLLATION=utf8_general_ci 设置默认校对规则，默认latin1_general_ci
-DWITH_INNOBASE_STORAGE_ENGINE=1 添加InnoDB引擎支持

-DMYSQL_TCP_PORT=3306 设置服务器监听端口，默认3306
-DSYSCONFDIR=/etc/mysql/conf 设置my.cnf所在目录，默认为安装目录

4、make && make install
5、 groupadd mysql　创建用户组
6、 useradd -r -g mysql -s /bin/false mysql　创建用户　且设置为非登录用户
７、初始化数据库
/usr/local/mysql/bin/mysqld --initialize --user=mysql
/usr/local/mysql/bin/mysql_ssl_rsa_setup
８、cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

vim mysqld
basedir=/usr/local/mysql
datadir=/home/mysqlData

9、sysv-rc-conf 　mysqld 添加到服务列表
10、sysv-rc-conf mysqld on 开启启动

添加到环境变量
vim /etc/profile.d/mysql.sh 写入：export PATH=$PATH:/usr/local/mysql/bin
source /etc/profile 是环境变量生效

PHP安装：

安装前准备
groupadd www
useradd -r -g www -s /bin/false www

　　 cd /usr/local/php74/etc/
　　cp php-fpm.conf.default php-fpm.conf
　　cd php-fpm.d/
　　cp www.conf.default www.conf

vim php-fpm.conf
去掉　pid = run/php-fpm.pid　之前的分好

5、vim /lib/systemd/system/php-fpm74.service 放入一下代码：

    *)
        echo "Usage: $0 {start|stop|force-quit|restart|reload|status|configtest}"
        exit 1
    ;;
 
esac

7、重载进程　systemctl daemon-reload

８、加到服务列表且设置开启自启　：sysv-rc-conf php-fpm74 　＆　 sysv-rc-conf php-fpm74 on
９、设置环境变量

添加到环境变量
vim /etc/profile.d/php.sh 写入：export PATH=$PATH:/usr/local/php74/bin
source /etc/profile 是环境变量生效
