Centos 7.4Linux系统lamp环境安装

前端之家收集整理的这篇文章主要介绍了Centos 7.4Linux系统lamp环境安装前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

安装Apache前的依赖包的安装

编译安装apr(apr-1.5.2.tar.gz)

下载地址:https://mirrors.cnnic.cn/apache/apr/apr-1.6.3.tar.gz

[root@server1 src]# tar zxvf apr-1.6.3.tar.gz   
[root@server1 src]# cd apr-1.6.3
[root@server1 apr-1.6.3]# ./configure --prefix=/usr/local/apr
[root@server1 apr-1.6.3]# make && make install

编译安装apr-util(apr-util-1.6.1.tar.gz)

下载地址: https://mirrors.cnnic.cn/apache//apr/apr-util-1.6.1.tar.gz

[root@server1 src]# tar zxvf apr-util-1.6.1.tar.gz
[root@server1 apr-util-1.6.1]# ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr    #编译安装apr-util必须指定apr的安装位置
[root@server1 apr-util-1.5.4]# make && make install

报错:fatal error: expat.h: No such file or directory


解决方式:yum install expat-devel

后重新编译,不再报错

编译安装pcre (pcre-8.38.tar.gz) ## 此处你也可以进行本地RPM包的安装

下载地址:https://sourceforge.net/projects/pcre/files/pcre/8.38/pcre-8.38.tar.gz/download

问题:用wget下载后文件名为download

解决方法:使用mv重命名文件pcre-8.38.tar.gz

[root@server1 src]# tar zxvf pcre-8.38.tar.gz
[root@server1 src]# cd pcre-8.38
[root@server1 pcre-8.38]# ./configure --prefix=/usr/local/pcre

报错:error: You need a C++ compiler for C++ support

解决方法yum install -y gcc gcc-c++

[root@server1 src]# make && make install

编译安装Apache

下载地址http://mirrors.tuna.tsinghua.edu.cn/apache//httpd/httpd-2.4.29.tar.gz


[root@server1 src]# tar zxvf httpd-2.4.29.tar.gz
[root@server1 src]# cd httpd-2.4.29
[root@server1 httpd-2.4.29]# ./configure \
--prefix=/usr/local/apache --sysconfdir=/etc/httpd \--enable-so --enable-ssl --enable-cgi --enable-rewrite \--with-zlib --with-pcre=/usr/local/pcre \--with-apr=/usr/local/apr \--with-apr-util=/usr/local/apr-util \--enable-mods-shared=most --enable-mpms-shared=all \--with-mpm=event

错误error: mod_ssl has been requested but can not be built due to prerequisite failures


解决方法其实是没有安装OpenSSL-devel

yum install openssl-devel

[root@server1 httpd-2.4.29]# make && make install
选项解释:
--prefix=/usr/local/apache    # 指定安装目录
--sysconfdir=/etc/httpd    # 指定配置文件安装路径
--enable-so   #允许运行时加载DSO模块 
--enable-ssl  # 启动ssl加密功能
--enable-cgi # 启用cgi协议
--enable-rewrite  #启用URL重写功能 
--with-zlib --with-pcre   # 指定pcre的安装路径  --with-apr=/usr/local/apr   #指定apr的安装路径--with-apr-util=/usr/local/apr-util   # 指定apr-util的安装路径--enable-modules=most   # 启用大多数共享模块
--enable-mpms-shared=most  #启用MPM大多数参数
--with-mpm=event  #指定使用的MPM的类型

启动Apache服务并验证

[root@server1 bin]# ./apachectl start   # 找到我们编译安装时指定的安装路径下bin目录下
[root@server1 bin]# curl http://localhost   # 验证apache是否可以正常访问

修改apache配置文件并设置PidFile路径(默认在/usr/local/apache/logs/httpd.pid)

[root@server1 bin]# ./apachectl stop    # 先停止apache服务
[root@server1 bin]# vim /etc/httpd/httpd.conf   # 添加以下内容
        PidFile  "/var/run/httpd.pid"
[root@server1 bin]# ./apachectl start

编写服务脚本/etc/init.d/httpd,让其可以使用service起停,并可以加到服务列表中

[root@server1 ~]# vim /etc/init.d/httpd   #添加以下内容
#!/bin/bash
#
# httpd        Startup script for the Apache HTTP Server
#
# chkconfig: - 85 15
# description: Apache is a World Wide Web server.  It is used to serve \
#         HTML files and CGI.

<1> 给脚本添加执行权限

[root@server1 ~]# chmod +x /etc/init.d/httpd
[root@server1 ~]# service httpd start

[root@server1 ~]# service httpd status


<2> 将httpd服务加到服务列表中,并设置在235级别开机启动

[root@server1 ~]# chkconfig --add httpd
[root@server1 ~]# chkconfig httpd --level 235 on
[root@server1 ~]# chkconfig --list httpd
httpd        0:off   1:off   2:on    3:on    4:off   5:on    6:off

/usr/local/apache/bin加入到PATH路径中去,让其中的命令可以进行全局执行

[root@server1 ~]# vim /etc/profile.d/apache.sh    # 脚本的名字必须要以.sh命名
export PATH=$PATH:/usr/local/apache/bin

编译安装MysqL前预准备

编译安装cmake工具(cmake-3.5.2.tar.gz)

下载地址:https://cmake.org/files/v3.5/cmake-3.5.2.tar.gz

[root@server1 src]# tar zxvf cmake-3.5.2.tar.gz
[root@server1 src]# cd cmake-3.5.2
[root@server1 cmake-3.5.2]# ./bootstrap --prefix=/usr/local/cmake
[root@server1 cmake-3.5.2]# gmake & gmake install   #默认安装到/usr/local/bin/cmake
[root@server1 ~]# vim /etc/profile.d/cmake.sh  # 将/usr/local/bin加到PATH中
export PATH=$PATH:/usr/local/cmake/bin

通过yum安装MysqL编译需要的依赖包

[root@server1 src]# yum install gcc gcc-c++ perl

下载MysqL5.6安装包,MysqL5.6安装包下载地址

https://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.36.tar.gz

添加MysqL用户组和用户,以及MysqL的安装目录

[root@server1 src]# groupadd MysqL
[root@server1 src]# useradd -g MysqL -s /sbin/nologin -M MysqL
[root@server1 src]# mkdir /usr/local/MysqL
[root@server1 src]# id MysqL
uid=501(MysqL) gid=501(MysqL) groups=501(MysqL)

MysqL的安装目录授权

[root@server1 src]# chown -R MysqL.MysqL /usr/local/MysqL
[root@server1 src]# ll /usr/local

添加MysqL环境变量

[root@server1 MysqL]# vim /etc/profile.d/MysqL.sh
export PATH=$PATH:/usr/local/MysqL/bin

安装依赖

yum -y install ncurses-devel

开始安装

解压缩之后进入,MysqL5.6起都是通过cmake的方式进行配置的,可以直接采用默认的方式cmake .就能直接进入配置,也可以自己指定配置,下面自己执行配置,修改一些常规的MysqL配置井号#后面是注释

[root@server1 MysqL-5.6.36]# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/MysqL -DMysqL_UNIX_ADDR=/usr/local/MysqL/MysqL.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DMysqL_DATADIR=/usr/local/MysqL/data -DMysqL_TCP_PORT=3306 -DENABLE_DOWNLOADS=1
参数介绍:

-DCMAKE_INSTALL_PREFIX=/usr/local/MysqL \   #指定安装目录> 
-DMysqL_UNIX_ADDR=/usr/local/MysqL/MysqL.sock \#指定MysqL.sock地址> 
-DDEFAULT_CHARSET=utf8 \#指定默认的字符集>
 -DDEFAULT_COLLATION=utf8_general_ci \#指定默认的排序字符集> 
-DWITH_INNOBASE_STORAGE_ENGINE=1 \#安装innodb存储引擎> 
-DWITH_MYISAM_STORAGE_ENGINE=1 \安装myisam存储引擎> 
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \安装archive存储引擎> 
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \安装blackhole存储引擎> 
-DMysqL_DATADIR=/usr/local/MysqL/data \#MysqL数据文件存放目录> 
-DMysqL_TCP_PORT=3306 \#端口> 
-DENABLE_DOWNLOADS=1

问题:command not found

原因:设置系统环境变量未成功

解决方法需要在终端执行 命令:

export PATH=$PATH:/usr/local/cmake/bin

再执行cmake软件编译就没有错误提示

make && make install

安装数据文件

MysqL安装完成之后需要安装文件,在MysqL的安装目录下的scripts文件夹里可以看到MysqL_install_db,用来安装MysqL数据文件,指定MysqL用户

[root@server1 MysqL]# ls /usr/local/MysqL/scripts/
MysqL_install_db
[root@server1 MysqL]# cd /usr/local/MysqL/scripts/
[root@server1 MysqL]# ./MysqL_install_db --user=MysqL --basedir=/usr/local/MysqL --datadir=/usr/local/MysqL/data

问题:-bash: ./MysqL_install_db: Permission denied

解决方法:命令:chmod +x MysqL_install_db

问题:FATAL ERROR: please install the following Perl modules before executing ./MysqL_install_db:

解决方法安装autoconf库

命令:

yum -y install autoconf  //此包安装时会安装Data:Dumper模块

加入服务列表并设置为开机自启

[root@server1 ~]# cd /usr/local/MysqL/support-files/
[root@server1 support-files]# cp MysqL.server  /etc/init.d/MysqLd
[root@server1 support-files]# chmod +x /etc/init.d/MysqLd   # 添加一个执行权限
[root@server1 support-files]# chkconfig MysqLd on
[root@server1 support-files]# chkconfig MysqLd --level 2345 on
[root@server1 support-files]# chkconfig --list MysqLd
MysqLd          0:off   1:off   2:on    3:on    4:on    5:on    6:off

修改MysqL配置文件,以下内容为自选

[root@server1 ~]# vim /etc/my.cnf
[client]port = 3306socket = /tmp/MysqL.sock
default-character-set = utf8mb4

[MysqLd]

初始化MysqL自身的数据库

##“-–initialize”生成一个随机密码(~/.MysqL_secret),而”–initialize-insecure”不会生成密码 ##user表示指定用户 ##basedir表示MysqL的安装路径,# datadir表示数据库文件存放路径

问题:-bash: MysqLd: command not found

解决方法

命令:

export PATH=$PATH:/usr/local/MysqL/bin
[root@server1 ~]# MysqLd --initialize-insecure --user=MysqL --basedir=/usr/local/MysqL --datadir=/usr/local/MysqL/data/

注意:需要创建log目录及两个log

[root@server1 ~]# mkdir /usr/local/MysqL/data/log
[root@server1 ~]# vim /usr/local/MysqL/data/log/MysqL-slow.log
[root@server1 ~]# vim /usr/local/MysqL/data/log/MysqL-error.log

启动MysqL数据库

[root@server1 ~]# MysqLd_safe –user=MysqL –datadir=/usr/local/MysqL/data/ ## datadir指定数据目录 
[root@server1 ~]# service MysqLd start

查看MysqL服务的进程和端口

[root@server1 ~]# ps -ef | grep MysqLd

[root@server1~]#netstat-anp|grep3306


登录MysqL 设置密码


注:刚安装完成的MysqL是没有密码的,输入密码时直接敲回车即可

输入update MysqL.user set password=password('111111') where user='root';

刷新权限:

flush privileges;

完成MysqL安装。


编译安装PHP前预准备


如果想让编译的PHP支持mcrypt扩展,还需要下载的PHP扩展包(mcrypt-2.6.8.tar.gzlibmcrypt-2.5.8.tar.gzmhash-0.9.9.9.tar.gz)

下载地址:
http://downloads.sourceforge.net/mcrypt/mcrypt-2.6.8.tar.gz
http://downloads.sourceforge.net/mcrypt/libmcrypt-2.5.8.tar.gz
http://downloads.sourceforge.net/mhash/mhash-0.9.9.9.tar.gz

安装顺序( libmcrypt –> mhash –> mcrypt )

编译安装libmcrypt(libmcrypt-2.5.8.tar.gz)

[root@server1 src]# tar zxvf libmcrypt-2.5.8.tar.gz
[root@server1 src]# cd libmcrypt-2.5.8
[root@server1 libmcrypt-2.5.8]# ./configure --prefix=/usr/local/libmcrypt
[root@server1 libmcrypt-2.5.8]# make && make install 
[root@server1 libmcrypt-2.5.8]# vim /etc/ld.so.conf.d/libmcrypt.conf  # 此选项为将libmcrypt的库文件能让系统找到,不然后面编译安装mcrypt会报错
/usr/local/libmcrypt/lib
[root@server1 libmcrypt-2.5.8]# ldconfig -v # 重新加载库文件

编译安装mhash(mhash-0.9.9.9.tar.gz)

[root@server1 src]# tar -zxvf mhash-0.9.9.9.tar.gz
[root@server1 src]# cd mhash-0.9.9.9
[root@server1 mhash-0.9.9.9]# ./configure
[root@server1 mhash-0.9.9.9]# make && make install
[root@server1 mhash-0.9.9.9]# vim /etc/ld.so.conf.d/mhash.conf  # 做添加mhash的库文件让系统找到,不然后面编译安装mcrypt会报错
/usr/local/mhash/lib
[root@server1 mhash-0.9.9.9]# ldconfig -v # 重新加载库文件

编译安装mcrypy(mcrypt-2.6.8.tar.gz)

[root@server1 src]# tar zxvf mcrypt-2.6.8.tar.gz
[root@server1 src]# cd mcrypt-2.6.8
[root@server1 mcrypt-2.6.8]# ./configure --with-libmcrypt-prefix=/usr/local/libmcrypt/
[root@server1 mcrypt-2.6.8]# make && make install

问题:configure: error: "You need at least libmhash 0.8.15 to compile this program

解决方法打开/etc/ld.so.conf,在文件之后,添加一行:

/usr/local/lib

然后,执行 ldconfig-v,重新编译即可。

编译安装PHP

下载地址:http://cn2.php.net/distributions/php-7.0.2.tar.gz

[root@server1 src]# tar -zxvf PHP-7.0.2.tar.gz
[root@server1 PHP-7.0.2]#
./configure --prefix=/usr/local/PHP --with-pdo-MysqL=MysqLnd --with-openssl --with-MysqLi=MysqLnd --enable-mbstring --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml  --enable-sockets --with-apxs2=/usr/local/apache/bin/apxs --with-mcrypt  --with-config-file-path=/etc --with-config-file-scan-dir=/etc/PHP.d --with-bz2  --enable-maintainer-zts
问题:error: xml2-config not found. Please check your libxml2 installation

解决方法

检查是否安装了libxm包

rpm -qa |grep libxml2
重新安装libxml2和libxml2-devel包
yum install libxml2
yum install libxml2-devel -y
问题:Please reinstall the BZip2 distribution
解决:yuminstallbzip2bzip2-devel
问题:mcrypt.h not found. Please reinstall libmcrypt
解决:yum install libmcrypt libmcrypt-devel
[root@server1 PHP-7.0.2]#
./configure --prefix=/usr/local/PHP --with-pdo-MysqL=MysqLnd --with-openssl --with-MysqLi=MysqLnd --enable-mbstring --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml  --enable-sockets --with-apxs2=/usr/local/apache/bin/apxs --with-mcrypt  --with-config-file-path=/etc --with-config-file-scan-dir=/etc/PHP.d --with-bz2  --enable-maintainer-zts

[root@server1 PHP-7.0.2]# make && make install
参数解释:
--prefix=/usr/local/PHP  # 指定PHP安装的路径
--with-pdo-MysqL=MysqLnd # 指定MysqL的安装目录 
--with-openssl #支持ssl功能
--with-MysqLi=MysqLnd # 可以让MysqLPHP结合的接口
--enable-mbstring --with-freetype-dir  # 指定可以支持中文非一个字节能表示语言  # 加载freetype的头文件,可以支持不同字体
--with-jpeg-dir --with-png-dir # 支持jpep格式图片 #支持pnp格式图片
--with-zlib --with-libxml-dir=/usr # 支持压缩库  # 指定xml的库路径
--enable-xml  --enable-sockets  #支持扩展标记语言  # 支持套接字的通信功能
--with-mcrypt  --with-config-file-path=/etc  # 支持额外的加密功能的库  # 指定PHP配置文件的路径(/etc/PHP.ini)
--with-config-file-scan-dir=/etc/PHP.d  # 支持PHP文件的附件配置文件(/etc/PHP.d/*.ini)
--with-bz2  --enable-maintainer-zts #支持bz2的压缩库  # 此选项是否安装取决于你的Apache工作的mpm模式
说明:
这里为了支持apache的worker或event这两个MPM,编译时使用了–enable-maintainer-zts选项。【prefork不需要加载】【event或work 
mpm工作模式必须要加此选项】 验证Apache mpm工作模式命令:httpd -M 
2、如果使用PHP5.3以上版本,为了链接MysqL数据库,可以指定MysqLnd,这样在本机就不需要先安装MysqLMysqL开发包了。MysqLnd从PHP5.3开始可用,可以编译时绑定到它(而不用和具体的MysqL客户端库绑定形成依赖),但从PHP 5.4开始它就是默认设置了。 ./configure –with-MysqL=MysqLnd –with-pdo-MysqL=MysqLnd 
–with-MysqLi=MysqLnd

PHP提供配置文件

[root@server1 PHP-5.5.36]# cp PHP.ini-production /etc/PHP.ini

编辑apache配置文件httpd.conf,以apache支持PHP

[root@server1 ~]# vim /etc/httpd/httpd.conf

<1> 添加如下二行

AddType application/x-httpd-PHP  .PHP
AddType application/x-httpd-PHP-source  .PHPs

<2> 定位至DirectoryIndex index.html

修改为:

DirectoryIndex  index.PHP  index.html

重启apache服务

[root@server1 ~]# service httpd restart
Stopping httpd:                                            [  OK  ]
Starting httpd:                                            [  OK  ]
[root@server1 ~]# netstat -an | grep :80   # apache已启动,并监听80端口
tcp        0      0 :::80       :::*         LISTEN

编辑Apache的网页测试是否支持PHP

[root@server1 ~]# cd /usr/local/apache/htdocs/
[root@server1 htdocs]# vim index.PHP
    <?PHP
    PHPinfo();
    ?>

问题:外网无法80端口

解决关闭默认防火墙 使用iptables

systemctl stop firewald.service

禁止开机自启:

systemctl disable firewalld

安装iptables

yum install iptables-services iptables-devel

启用并启动iptables

systemctl enable iptables.service && systemctl start iptables.service

查看iptables配置文件并开放803306端口

vim /etc/sysconfig/iptables

在里面添加两行:

-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT

重启防火墙

systemctl  restart  iptables

设置iptables防火墙为开机启动项

systemctl enable iptables

关闭SELINUX

vi /etc/selinux/config
#注释以下配置 
SELINUX=enforcing 
SELINUXTYPE=targeted 
  
#增加以下配置 
SELINUX=disabled 
  
#使配置立即生效 
setenforce 0


编辑Apache的网页测试PHP是否可以连接MysqL

[root@server1 htdocs]# vim index.PHP
<?PHP
  $conn=MysqLi_connect('127.0.0.1','root','111111');   
  if ($conn)
        echo "Success...";
  else
        echo "Failure...";
?>

完成!!!
