LNMP編譯安裝-week16

1、源碼編譯安裝LNMP架構環境；

系統： CentOS 7.2
IP: 172.16.0.11
版本: nginx-1.10.3 php-5.6.30 mysql-5.6.30

一.安裝開發包組

~]# yum -y groupinstall "Development Tools" "Server Platform Development"

二.編譯安裝nginx-1.10.3

(1) 安裝依賴包

~]# yum -y install openssl-devel pcre-devel zlib-devel

(2) 創建nginx用戶和組

~]# useradd -r nginx

(3) 編譯安裝

~]# tar xf nginx-1.10.3.tar.gz
~]# cd nginx-1.10.3/
]# ./configure --prefix=/usr/local/nginx --conf-path=/etc/nginx/nginx.conf --user=nginx --group=nginx --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/lock/nginx.lock --with-http_ssl_module --with-http_gzip_static_module --with-debug --with-http_stub_status_module
]# make && make install

(4) 啟動nginx

]# /usr/local/nginx/sbin/nginx

(5) 測試頁:

問題1： 重啟后執行/usr/local/nginx/sbin/nginx報錯，使用啟動腳本或者unit也無法啟動

]# /usr/local/nginx/sbin/nginx
[root@localhost ~]# nginx: [emerg] open() "/var/run/nginx/nginx.pid" failed (2: No such file or directory)

原因： 系統中沒有/var/run/nginx目錄，手動創建，即可執行成功，但/var/run/nginx下面的目錄重啟后就沒有了，所以我覺得pid目錄設置為/var/run/nginx.pid會好一些，因此上面的configure語句已經修改過并重新執行，證實該問題已經解決

(5) nginx開機啟動(啟動腳本)

]# vim /etc/rc.d/init.d/nginx
#! /bin/bash
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig:   - 85 15

    [ -x $nginx ] || exit 5
    [ -f $NGINX_CONF_FILE ] || exit 6
    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
}

    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

備注：腳本中pid文件改成如下路徑（和configure中一致），否則無法啟動服務

# pidfile:     /var/run/nginx.pid

授權

]# chmod +x /etc/rc.d/init.d/nginx

設置開機自啟動

]# chkconfig --add nginx
]# chkconfig nginx on
]# chkconfig --list nginx

三.安裝mysql-5.6.30

(1) 下載mysql

]# cd /usr/local/src
]# wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.30.tar.gz

(2) 安裝編譯源碼所需的工具和庫

]# yum -y install cmake ncurses-devel

(3) 設置MySQL用戶和組

]# useradd -r mysql

(4) 編譯安裝

]# cd /usr/local/src
]# tar xf mysql-5.6.30.tar.gz
]# cd mysql-5.6.30/
]# 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_MEMORY_STORAGE_ENGINE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DMYSQL_DATADIR=/data/mysqldb -DMYSQL_TCP_PORT=3306 -DENABLE_DOWNLOADS=1 -DEXTRA_CHARSETS=all -DENABLED_LOCAL_INFILE=1 -DWITH_READLINE=1

(注：重新運行配置，需要刪除CMakeCache.txt文件 rm CMakeCache.txt )   
]# make -j 4 && make install

(5) 初始化數據庫

]# mkdir -p /data/mysqldb      #創建數據庫數據目錄  
]# chown -R mysql.mysql /usr/local/mysql   # 給程序目錄授權,否則socket文件無法寫入到該目錄
]# chown -R mysql.mysql /data/mysqldb/   #給數據目錄授權
]# cd /usr/local/mysql/
]# ./scripts/mysql_install_db --user=mysql --datadir=/data/mysqldb   


參考: /usr/local/mysql/scripts/mysql_install_db --defaults-file=/etc/my.cnf --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql

(6) 準備mysql配置文件

]# cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf    （注：如果/etc/my.cnf文件存在，則覆蓋。）  
]# vim /etc/my.cnf
[mysqld]
...
datadir = /data/mysqldb
innodb_file_per_table = ON
skip_name_resolve = ON
...

(7) 復制mysql啟動腳本

]# cp support-files/mysql.server /etc/rc.d/init.d/mysqld
]# sed  -i 's@^basedir=@basedir=/usr/local/mysql@' /etc/init.d/mysqld
]# sed  -i 's@^datadir=@datadir=/data/mysqldb@' /etc/init.d/mysqld

(8) 啟動mysql服務并設置開機自啟動

]# service mysqld start
Starting MySQL... SUCCESS!
]# chkconfig --add mysqld
]# chkconfig --level 35 mysqld on

查看是否啟動

[root@localhost mysqldb]# ss -tnlp | grep 3306
LISTEN     0      80          :::3306                    :::*                   users:(("mysqld",pid=2812,fd=10))

檢查開機啟動

]# ss -tnlp | grep 3306
LISTEN     0      80          :::3306                    :::*                   users:(("mysqld",pid=1028,fd=10))

(9) 設置環境變量

]# echo "export PATH=/usr/local/mysql/bin:$PATH" > /etc/profile.d/mysql.sh
[root@localhost ~]# source /etc/profile.d/mysql.sh

(10) 測試登錄,默認是沒有密碼,直接回車就可進入

]# mysql -uroot -p
Enter password:

mysql>

(11) 修改MySQL用戶root的密碼,此時使用安全加固方法

]# mysql_secure_installation



NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MySQL to secure it, we'll need the current
password for the root user.  If you've just installed MySQL, 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 MySQL
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 MySQL installation has an anonymous user, allowing anyone
to log into MySQL 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] n
 ... skipping.

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] n
 ... skipping.

By default, MySQL 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!




All done!  If you've completed all of the above steps, your MySQL
installation should now be secure.

Thanks for using MySQL!


Cleaning up...

方法一：mysql -u root -p
use mysql
update user set password=password(‘123456’) where user=’root’
flush privileges(刷新權限)
方法二：/usr/local/mysql/bin/mysql_secure_installation
（修改MySQL用戶root的密碼，同時可禁止root遠程連接，移除test數據庫和匿名用戶。）
方法三: /usr/local/mysql/bin/mysqladmin -uroot -p password ‘你的密碼’

(12) 輸出mysql的頭文件至系統頭文件路徑/usr/include(非必須)

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

(13) 輸出mysql的庫文件給系統庫查找路徑(非必須)

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

問題2:啟動服務報錯

]# service mysqld start
Starting MySQL.... ERROR! The server quit without updating PID file (/data/mysqldb/localhost.localdomain.pid).

]# vim localhost.localdomain.err
2017-05-07 23:29:40 2496 [ERROR] Can't start server : Bind on unix socket: Permission denied
2017-05-07 23:29:40 2496 [ERROR] Do you already have another mysqld server running on socket: /usr/local/mysql/mysql.sock ?
2017-05-07 23:29:40 2496 [ERROR] Aborting  

找到原因: 因為mysql帳號對/usr/local/mysql沒有寫權限,無法創建socket文件  

解決方法: 
]# chown -R mysql.mysql /usr/local/mysql
[root@localhost mysqldb]# service mysqld start
Starting MySQL... SUCCESS!

四. php安裝

(1) PHP添加libmcrypt拓展

[root@localhost ~]# tar xf libmcrypt-2.5.8.tar.bz2
[root@localhost ~]# cd libmcrypt-2.5.8/
[root@localhost libmcrypt-2.5.8]# ./configure --prefix=/usr/local/libmcrypt
[root@localhost ~]# make && make install && cd
[root@localhost ~]# sed -i '1a/usr/local/libmcrypt/lib' /etc/ld.so.conf

(2) 解決依賴

[root@localhost ~]# yum -y install php-pear
[root@localhost ~]# yum -y install libxml2-devel libcurl-devel libjpeg-devel libpng-devel freetype freetype-devel

(3) 編譯安裝php-5.6

[root@localhost ~]# tar xf php-5.6.30.tar.bz2 
[root@localhost ~]# cd php-5.6.30/
[root@localhost php-5.6.30]# ./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php  --with-mysql=mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-iconv-dir --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-fpm --enable-mbstring --with-gd --enable-gd-native-ttf --with-mhash  --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --with-mcrypt=/usr/local/libmcrypt/ --with-gettext
[root@localhost php-5.6.30]# make && make install

(4) 復制php配置文件

[root@localhost php-5.6.30]# cp php.ini-production /usr/local/php/etc/php.ini

(5) 復制php-fpm配置文件

[root@localhost php-5.6.30]# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf

(6) 復制php-fpm啟動腳本到init.d,設置開機啟動

[root@localhost php-5.6.30]# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
[root@localhost php-5.6.30]# cd
[root@localhost ~]# chmod +x /etc/rc.d/init.d/php-fpm 
[root@localhost ~]# chkconfig --add php-fpm
[root@localhost ~]# chkconfig php-fpm on

(7) 立即啟動php-fpm

[root@localhost php]# service php-fpm start

(8) 修改nginx配置文件使之支持php

[root@localhost ~]# vim /etc/nginx/nginx.conf
修改
        #location ~ \.php$ {
        #    root           html;
        #    fastcgi_pass   127.0.0.1:9000;
        #    fastcgi_index  index.php;
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        #    include        fastcgi_params;
        #}
為
location ~ \.php$ {
    root           html;
    fastcgi_pass   127.0.0.1:9000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  /usr/local/nginx/html$fastcgi_script_name;
    include        fastcgi_params;
}

備注: #取消FastCGI server部分location的注釋,并要注意fastcgi_param行的參數,改為$document_root$fastcgi_script_name,或者使用絕對路徑  

測試一下是否有錯：
/usr/local/nginx/sbin/nginx -t
平滑重啟nginx
[root@localhost ~]# systemctl reload nginx
或 
[root@localhost ~]# /usr/local/nginx/sbin/nginx -s reload

五. 測試php和nginx和mysql

(1) 測試nginx和php的聯動

[root@localhost ~]# cat > /usr/local/nginx/html/index.php << EOF
<?php
    phpinfo()
?>
EOF

(2) 測試php與mysql的聯動

[root@localhost ~]# cat > /usr/local/nginx/html/index.php <<EOF
<?php
    \$conn = mysql_connect('127.0.0.1','root','123456');
    if (\$conn)
       echo "OK";
    else
       echo "Failure";
?>
EOF

問題3: 測試php和mysql聯動是有警告mysql_connect(): Headers and client library minor version mismatch ,該文檔已經修改過,無此錯誤
之前的錯誤圖片:

[root@localhost ~]# /usr/local/php/bin/php -i|grep Client
Client API version => 5.5.44-MariaDB
Client API library version => 5.5.44-MariaDB
Client API header version => 5.6.30
Soap Client => enabled

原因: 版本不兼容導致上述警告, 唉,新版本總會有各種各樣的問題!!!
new MySQL 5.6 family you need to install PHP with php5-mysqlnd, not php5-mysql
解決方法: 重新編譯

./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php  --with-mysql=mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-iconv-dir --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-fpm --enable-mbstring --with-gd --enable-gd-native-ttf --with-mhash  --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --with-mcrypt=/usr/local/libmcrypt/ --with-gettext

用
--with-mysql=mysqlnd 
--with-mysqli=mysqlnd 
--with-pdo-mysql=mysqlnd
替換掉原來的
--with-mysql=/usr/local/mysql
--with-mysqli=/usr/local/mysql/bin/mysql_config

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。

系統: centos7.2
(1) 準備程序

[root@localhost src]# pwd
/usr/local/src
[root@localhost src]# ls
libmcrypt-2.5.8.tar.bz2  lnmp_source.sh  nginx  nginx-1.10.3.tar.gz  php-5.6.30.tar.bz2

(2) 執行腳本

[root@localhost src]# chmod +x lnmp_source.sh
[root@localhost src]# ./lnmp_source.sh 2>&1 | tee lnmp_install.log
#安裝記錄輸出到文件,供分析錯誤用

(3) 腳本內容

]# cat lnmp_source.sh
#!/bin/bash
# lnmp 源碼安裝
# han
system_ready() {
        echo "安裝前環境準備..."
        sleep 3
        iptables -F
        systemctl stop firewalld.service
        systemctl disable firewalld.service
        setenforce 0 &> /dev/null
        sed -i -r 's/(SELINUX=).*/\1disabled/' /etc/selinux/config
        yum -y groupinstall "Development Tools" "Server Platform Development"
#返回一個值,判斷是否安裝成功
        [ $? -eq 0 ]  && return 2
}
nginx_install() {
        echo "開始安裝nginx"
        sleep 3
#編譯安裝
        yum -y install openssl-devel pcre-devel zlib-devel
        useradd -r nginx
        cd $tools
        tar xf nginx-1.10.3.tar.gz
        cd nginx-1.10.3/
        ./configure --prefix=$install/nginx --conf-path=/etc/nginx/nginx.conf --user=nginx --group=nginx --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/lock/nginx.lock --with-http_ssl_module --with-http_gzip_static_module --with-debug --with-http_stub_status_module
        make && make install
#設置開機自啟動
        cp $tools/nginx /etc/rc.d/init.d/nginx
        chmod +x /etc/rc.d/init.d/nginx
        chkconfig --add nginx
        chkconfig nginx on

#啟動ngnix
        /etc/init.d/nginx start

問題4: 腳本中無法使用service nginx start啟動服務
修改為/etc/init.d/nginx start
如果修改為/usr/local/nginx/sbin/nginx,后面systemctl reload nginx同樣出錯

問題5: sed腳本出錯,導致mysql安裝失敗

sed  -i 's#^basedir=#basedir=$install/mysql#' /etc/init.d/mysqld

解決方法: 把腳本中的單引號改成雙引號
備注: sed中可以使用變量,但記得使用雙引號
